SU20887A1 - Manual lubricating press with screw piston rod - Google Patents

Description

When using a conventional screw-type manual lubricating press, after using and subsequently reloading the press with lubricant, re-screw the piston in the opposite direction. D. To install it in the lid in the working position, the time is non-condensing. To eliminate this drawback and speed up the readiness of the press for work, the piston rod is supplied with two pistons located at its ends, and the lid with two threaded nozzles, which should make it possible, after emptying and then filling the press with a new lubricant charge, turning the screw rod and screwing the cover onto the press cylinder with its other branch pipe.

In FIG. 1 shows a press cylinder cover in a vertical section; ig. 2-screw rod with two pistons 3 longitudinal section; FIG. 3-longitudinal section of the stem handle.

The rod 2 with a screw thread is attached at its ends to two pistons 3–3 connected together and

screwed into the sleeve 5, mounted in the middle of the lid 1, provided with two end connections with cuts, through which the lid is to be screwed onto the press cylinder. or the other end. The handle 4 is put on one end of another or the other end of the rod 2 and fastened with it by means of projections on the surface of the conical recess, which coincides with the corresponding recesses, on the conical surfaces of both ends of the piece; ka 2.

- .P.: After using the press and its emptying from lubrication, one piston 3 is located near the exit end of the cylinder, whereas the other enters the outer connection of the cover 1. When the cylinder is recharged, the handle is removed, the cover 1 is removed and cylinder, the rod turns over to the other endorl and the cap is screwed onto the cylinder with a branch pipe that previously remained outside the cylinder, and the handle is put on the other end of the rod from the side of that piston 3 that remains outside the cylinder during press operation.

The subject of the patent.

A manual lubricating press with a screw piston rod, characterized in that, in order to eliminate the need for unscrewing the rod for reverse

moving the piston after squeezing the grease off, the rod 2 is provided with pistons at both ends, whereby the cover 1 has connections on both sides for fixing it on the cylinder of the press.
