VENTING DEVICE FOR USE WITH A LIQUID CONTAINER Filed Feb. 12, 1965 United States Patent VENTING DEVICE FOR USE WITH A LIQUID CONTAINER Richard William Ride], Acton, London, England, assignor to C.A.V. Limited, London, England Filed Feb. 12, 1965, Ser. No. 432,304 Claims priority, application Great Britain, Feb. 28, 1964, 8,338/64 1 Claim. (Cl. 137-525) ABSTRACT OF THE DISCLGSURE A venting device for a liquid container comprising a member defining an annular step mounted on the upper wall of the container with the step disposed in the container. The member having a circular plate secured to the lower end thereof and an annular flexible diaphragm secured at its outer periphery to the plate and having its inner peripheral surface overlapping the step. The member also having a passage through which a space defined between the diaphragm and the plate communicates with the exterior of the chamber.
This invention relates to a venting device for use with a liquid container and has for its object to provide such a device in a simple and convenient form.
A device in accordance with the invention comprises, in combination, a stepped member the narrower portion of which is adapted to be mounted in the upper wall of the container or a closure member thereof, so that the wider portion of the stepped member lies within the container, a plate secured to the Wider end of the stepped member, a flexible annular diaphragm having its outer marginal edges secured to the plate and arranged so that the inner marginal edges thereof bear against the step, and a passage within the stepped member for placing the space defined between the diaphragm and the plate in communication with the exterior of the container, the arrangement being such that when liquid is withdrawn from the container the diaphragm will be moved to allow air to enter the container.
The accompanying drawing shows a sectional side elevation of one example of a venting device in accordance with the invention together with a diagrammatic representation of one example of a fuel supply system for an internal combustion engine with which it can be associated.
Referring to the drawing there is provided a main fuel tank 1 for liquid fuel, the tank having a closable filling opening 2. Fuel is drawn from the tank 1 by an engine driven fuel pump 3 and is passed to a filter 4 of any convenient form. The filter is provided with two outlet pipes one of which communicates with a fuel injection pump 5 for supplying fuel under pressure to the engine, and the other pipe 6 communicates with a reservoir tank 7. Also associated with the filter 4 is a return pipe for returning excess fuel from the injection pump to the filter.
The reservoir tank is disposed at the highest point of the system and is provided with an overflow pipe which leads from the side of the tank at a level at which it is 3,361,159 Patented Jan. 2, 1968 desired the liquid fuel in the tank should attain, furthermore, the pipe 8 communicates with the main tank 1, and
the arrangement is such that when the pump 3 is operating i.e. when the engine is running the level of fuel in the 5 tank will be maintained substantially constant.
From the base of the tank extends: an outlet pipe 9 which communicates with an electric starting aid 10 disposed so that, when operated, it permits liquid fuel to flow from the tank and discharges it into the inlet manifold 11 of the engine to assist the starting of the engine. The starting aid incorporates a valve so that when the aid is out of use fuel is not delivered to the manifold. In order to permit fuel to flow by gravity to the aid air must be allowed to enter the tank '7 however, because the system may be mounted on a vehicle the tank must be closed to prevent the fuel in the tank splashing and for this purpose the tank is closed by a cap 12 and is provided with a vent.
The vent takes the form of a stepped cylindrical member 13 the narrower portion of which is screw threaded for engagement with a complementary thread in the cap. Secured to the end of the wider portion of the member is a dished plate 14 and which at its marginal edge is secured to the outer marginal edge of a flexible annular diaphragm 15. The diaphragm is shaped so that its inner marginal edge overlies the wider portion of the member 13 to constitute a flap valve. Furthermore the member 13 is provided with a bore 16 which, thuou-gh a groove 17 in the wider end of the member, communicates with a space defined between the diaphragm and the plate. In use, when the valve in the aid is operated the diaphragm is lifted off the member to allow air to enter the tank and thus permits fuel to leave the tank via the outlet pipe 9. However, when the aid is not being used the vent is closed and so external splashing of the fuel is prevented.
Having thus described by invention what I claim as new and desire to secure by Letters Patent is:
1. A venting device for a liquid container comprising in combination, a stepped member having a narrower and a wider portion which define an annular step, the member in use, being mounted on the upper wall of the container with the step being disposed within the container, a circular plate secured to the wider end of the member, a flexible annular diaphragm disposed above said plate and having its outer marginal edge secured in sealing relation- 45 ship to the periphery of the plate, the inner marginal edge of the diaphragm overlapping and forming a seal with said step, and a passage within the stepped member and through which the underside of the diaphragm is exposed to the pressure exterior of the container.
