Title:
2つの流体回路に同期的に圧力供給するポンプアセンブリ
Document Type and Number:
Japanese Patent JP2011503428
Kind Code:
A
Abstract:
The invention relates to a pump assembly for the synchronous pressurization of two fluid circuits. Two internal gear pumps are disposed together in a pump housing and rotationally driven by drive shafts thereof. Pinions of the pumps are located in an associated pump chamber and engage in an internal gear thereof. The pump chambers of the internal gear pumps are separated from each other by a common separating wall or partition, which is designed as a separate housing part and engages in a hollow cross-section of a housing part forming the circumferential wall of one of the internal gear pumps. Suction channels and pressure channels associated with the internal gear pumps transition into a radially extending longitudinal section in the pump housing following an axial longitudinal section in the lateral boundary wall of the associated pump chamber. According to the invention, a suction channel and a pressure channel of one of the internal gear pumps are integrated in the separating wall.
