Hydraulic motor-pump system

摘要

The hydraulic motor pump system has a housing (G). The housing contains an open electro-motor (M) and at least one pump element (P) driven by the motor shaft. The housing (G) forms an oil container. The housing (G) includes an upper cover (1), a main housing part (2), a housing cross-art (3) and a lower cover (4). The housing main part (2) contains the electro-motor (M). The cross-part (3) provides an open oil passage and contains a main bearing for the motor shaft. Each pump element (P) is fixed between the lower cover (4) and the housing cross-part (3). The latter part (3) is formed in one piece in the housing main part (2) which is formed as a moulded part.
