Abstract

2611. Liebau, R. April 12, 1913, [Convention date]. Single-acting bucket pumps.-Relates to fluidpressure cushioning - devices of the kind described in Specifications 21,558/10 and 29,449/12 in which a packed piston moves into and out of a cylinder partly containing liquid above which is air under pressure, a pump, operated by the relative movement of the piston, being employed to return the liquid which leaks past the piston packing to the pressure side of the packing. The present invention consists in providing a heavy pump plunger so that its inertia will effect the action of the pump. In the arrangement shown, any liquid which leaks past the packing 24 passes into the annular space between the parts 7, 9 of the piston. This liquid is returned by way of a passage 11 to the other side of the packing through the hollow pump plunger 13 which has a heavy top portion 16 acted upon by a spring 18, and is provided with ball valves 15, 22. The reciprocation of the pump plunger is effected by the inertia of its top portion acting in conjunction with the spring 18, the shock at the bottom of the stroke being cushioned by a buffer 17.
