Abstract
CHARGE AND RELIEF VALVE
ABSTRACT OF THE DISCLOSURE
A dual valve assembly having a charge and relief valve, comprising a unitary valve structure including a thick central body section and, extending therefrom, a pair of elongated hollow cylindrical valve members. A valve core is threaded into the bore of each valve member and a conventional valve cap is screwed onto the free end of one member, which end is adapted to be connected to an air source. A spring-biased plunger-cap or assembly is threaded onto the free end of the other valve member, the plunger being operable to engage the pin of the valve core at that end so as selectively to relieve the pressure. A passageway in the central section communicates with both of the bores and by a hose connection, with a pneumatic device whose operation is to be controlled.

Description
~95~ 3 ~ le preC;ent invention pc~rta:ins to a unitary valve struc--ture, and more particular.l.y, to a dua:l. valve assembly which uniquely incorporates the functions of a charcJe and relief valve in con trolli~ pressure to and rom devices operable by means of air pressure .
.In order to provide some backgroun~ for the present in-vention, reference may be made to multiple or dual valvé assemblies or like structures, as, for example, that disclosed in U. S. Paten-t 10 1,484,342, which assembly involves an adapter for pump couplings : including multiple valve cores.
Although there is provision in the valve assembly dis- .
, closed in U. S. Patent 1,484,342 for the utilization of two standard .. i . valve cores within bores in a valve body, nevertheless the whole purpose therein is directed to an operation involving the use of a pressure gauge, therefore necessarily involvlng the actuation or manipulation of two valve stems and accordingly, requiring that both of the valve cores be actuated in order to pass air into a utilization dev:ice such as a tire. Such an arrangernent is anti-thetical to the purpose and function of the present invention.
:' l : Instead of the above-described prior art arrangement, the present invention envisions the simple and ready adjustability, :` by means of a plunger cap, having a suitable vent hole, of the pressure which is being supplied to a vehicle seat ~r like devi.ce which is operable by means of air pressure~
Accor~incJly, it is a primary object of the present inven-tion to make Eeasible and convenient the connection to pre~sure lines in order to furnish pressure to a device such as a seat mechanism, and yet to permit easy adjustabllity and con-venience in regula-ting the pressure to suit, for example, a driver's comfort in respect to posi-tion and height in the use of the pneumatically operated vehicle seat.
Another and more specific object is to permit ready access in furnishing pressure to a vehicle seat or the like from a position on one side, for example, of a bulkhead such as be-tween a truck cab and an engine compartment. To this end the dual valve assembly is so arranged that one end of the assembly with its valve means i5 available to project into the aforesaid engine compartment or the like and the other end, furnished with a similar or corresponding valve means, is readily accessible within the truck cab for the driver's convenience in adjusting the air-controlled seat.
It will be appreciated that although reference has been made hereinabove to the specific example of the operation of a vehicle seat, the dual valve assembly of the present inven-tion is just as easily utilizable in other controls involving the general use of air bags, air springs, or other devices that employ air pressure and in which the same desirable ends are to be realized or achieved.
~ hese objects and advantages are satisfied by the pre-sent invention which specifically provides a dual valve assembly for enabling ready access in relieving air pressure from a util-ization device located on one side of a wall, and in furnishing air pressure to said utilization device from a source located on the opposite side of the wall, comprising (a) a unitary valve structure including a central body section and first and second integrally formed valves, each valve comprising ~,~

Although there is provision in the valve assembly dis- .

Such an arrangernent is anti-thetical to the purpose and function of the present invention.

' Referring now to Figs. 1 and 2, the unitary or dual valve assembly 10 of the present invention is illustrated. Normally the left s:ide o.r left end o~ the assen~ly is capped with a regular or standard valve cap 12 and -this end of the assembly typically would extend from one side of a bulkhead or wall 13 into, for example, an engine compartment 14. The valve cap 12 would be removed when it is desired that air be furnished to a.device 16, such as a :. vehicle seat, in the cab 18. The supply o~ air would come from a compressor 20 or other source by way of a hose 22 connected to the assembly by means o~ connector 24, and would be controlled by a ' separate valve 25.
The dual valve assembly 10 of the invention includes, in :' a unitary valve structure, two independently operable valves; that is, a charye valve'26 and a relief valve 28. '_'he uni-tary valve struc-ture includes a thick central body section 30, pre:Eerably hexagonal in outer con~igurat:ion and, extending t'herefrom, a pair of elonga-ted hollow valve cylinders 32 and 34.
, ; For convenience and low cost manufacture, it will be seen in the preferred embodiment that the hollow cylindrical members 32 and 34 are formed on a common axis from ei~her side of the thick body section 30 so that the bores 36 and 38 )f the respective valve :- :
1~5;~ 13 members can be formecl i n a s~ gle operat:ion as exlensions oE cach other Oll tllat axi5.
Valve core~s 40 and 42 are -threadedly enyaged with the internal thre~ds withi.n the respective bores 36 and 38.. These bores are appropriately stepped or cha~lpered so as to provide yood internal sealing and each of the valve cores includes a stem or pin 39 ~aving a cap at i-ts innex end which normally covers an out-let from the flow passage through the valve core.
The right~hand end o:~ the vaIve assembly 10 is capped or terminated with a cap 44 including a spring biased plunger 46 and fur-ther including an aperture or vent hole 48. The plunger 46 is operable, by reason of contacting pin 39, to cause deflation or release of pressure when desired. The cap 44 is engaged with the external threads 50 on valve member or cylinder 34.
It will be seen in Fig. 1 that fastening means, in the foxm of suitable hex nuts 52, are provided so that they may be .engaged, preferahly with external threads 54 on valve cylinder 32 so that the valve assembly 10 can be suitably attached o.r affixed to th.e bulkhead 13. If preferred, the valve assembly can be ;~ 20 attached or mounted to a bracket or the like, wherever conveni.ent~
, . . .
. ~ recess or bore 60 extends from another hexagonal face ~ of the body section 30 of the valve assembly 10 and terminates in a narrow passageway 62 which communicates with the bores 36 and 38 of the valve members. Accordingly, it will be understood that valves 26 and 28 are independently operable, v~lve 26 acting to .~ - 5 -105;~113 permi~ ~ fl()w of air to be furJli.sh~d to a utiliz~tion device and servi nCJ as a check val.ve at othe.r times; particularly when the other va.Lve 2~ is Eunct:iollincJ as a bleedinc3 or release valve by dint of operation of th~ plunger 46 on cap 44 whereby the stem or pin 39 o~ valve core 42 is en~acJed and air can then readily flow out by way of vent hoIe 48 in the cap.
When air is being supplied from compressor 20, theYe will be flow through the bore 60, thence to a hose 70 sui.tably connected to that bore and ultimately to an air bag 72 forming part of the vehicle seat 16. Accordihgly, sufficient air can be supplied to the air bag to provide a comfortable level for the driver of the vehicle or the like. However, in the event that that driver, or another driver subsequent].y operating the vehicle, decides to de-crease the pressure in the air bag, the plunger 46 on the cap 44 is pushed inwardly with consequent release oE pressure. such that the vehicle seat will be lowered.
While there has been shown and descr:i~ed what is con-sidered at present to be the preferred embodiment o~ the present invention, it will be appreciated by those skillecl in the a.rt that modifications of such embodîment may be made. It is therefore desired that the invention not be limited to this embodiment, and it is intended to cover in the appended claims all such modifica-tions as fall within the true spi~i.t and scope of th~ invention.
