| 摘要 |
The invention relates to a pump assembly (10) for the synchronous pressurization of two fluid circuits, comprising two internal gear pumps (11, 11') disposed together in a pump housing (12) and rotationally driven by the drive shafts (16) thereof, the pinions (19, 19') of said pumps being located in the associated pump chamber and engaging in the internal gear (21, 21') thereof. The pump chambers of the internal gear pumps (11, 11') are separated from each other by a common separating wall (15), which is designed as a separate housing part and engages in a hollow cross-section of a housing part (13) forming the circumferential wall of one of the internal gear pumps (11, 11'). Suction channels (24, 24') and pressure channels (25, 25') associated with the internal gear pumps (1, 11') transition into a radially extending longitudinal section in the pump housing (12) following an axial longitudinal section in the lateral boundary wall of the associated pump chamber. According to the invention, the suction channel (24, 24') and the pressure channel (25, 25') of one of the internal gear pumps (11, 11') are integrated in the separating wall (15). |
