Abstract (en)
The body (2) of the hydraulic pump which contains the movable gearing (3) between bearings (4,5) is supported by a base plate (1). The pump body is connected to an auxiliary pump body (11) by bolts. The auxiliary pump does not have any gearing and the gear pump outlet pipe (8) discharges into the auxiliary pump cavity (12). The outlet pipe is connected to the cavity by a calibrated tube (18). The gear pump is separated from the auxiliary pump by a closing plate (10). The two pump bodies are connected by bolts (15). The auxiliary pump is closed by a cover (14).
