SU51145A1 - Central lubrication device - Google Patents

Description

It is proposed in the known devices for central lubrication with the use of separate lubricators combined with a common oil supply and feeding a fairy tale under the pressure of compressed air in them, to use a special valve at the intersection of the supply and exhaust oil lines of each lubricator; This valve, through a radial channel arranged in it, connects the reservoir of the oil can either to the oil outlet or to the feed, depending on the pressure in the oil feed.

In FIG. Figure 1 shows a longitudinal section of an oil can at its connection with the feed and discharge oil lines; Fig. 2 shows the arrangement of the lubricators and the location of the discharge and safety valve.

The proposed device for central lubrication consists of attached to the feed oil pipe / oilers 2, made in the form of a tank 3 with a ball air valve 4 and a slide valve 5, located at the intersection of the oil pipeline /

and a diverter S, provided with a radial channel b and a spring-loaded helical spring a.

Oil under pressure enters through valve 6, fills the oil pipe /, opens the spool valve 5, moving it to the right (according to the drawing), and enters the reservoir 5; when the oil level in tank 5 rises to the valve, the latter, closing, stops access to the outside air tank, and as the oil enters the tank 3, the air there is compressed, forming an air liner.

The flow of oil through the valve 5 occurs at a set pressure; By filling all tanks with oil, the oil pressure in the system rises, as a result of which the safety valve 7 opens, releasing excess oil. At this moment, the oil supply through the oil pipe} stops and the valve 5 under the action of the spring and moves to the left, the channel b is connected to the channel in the tank and the oil outlet pipe 8, and the oil under pressure of air in the tank 5 is supplied to the destination. Pre-supply of oil to reservoir 3, i.e., it is charged by a manual pump.

The device is designed to lubricate a variety of mechanisms.

The subject matter of the invention.

A device for central lubrication using separate lubricators connected by a common oil supplying them and supplying oil

under pressure of compressed air, characterized by the use of a spring-loaded valve 5, placed at the intersection of the supply and discharge oil lines near each lubricator and provided with a radial channel b in its body to connect the lubricator container 3 or with the exhaust oil line or supply, depending on pressure in the supply oil pipe. copyright certificate G.
