APPARATUS FOR FILLING THE SUCTION CHAMBER OF A PUMP AT HIGH-PUMP SPEEDS

摘要

An apparatus including a valve for connecting the pressure discharge conduit of a pump with the suction conduit only at high-pump speeds so that the machine driven by the pump is partly bypassed. The pressure medium is accelerated in the suction conduit and applies suction to the outlet conduit of a container for the medium, which is connected by a filling conduit and by a single groove in the valve piston, with the suction conduit so that the suction chamber of the pump is completely filled.
