Hydraulic system for providing an auxiliary force for a motor vehicle device

摘要

A hydraulic system for providing an auxiliary force for a motor vehicle device has a fluid circulation system. The fluid circulation system includes a pump ( 14 ), an electromotor ( 16 ) and a reservoir ( 12 ). The pump ( 14 ) delivers fluid from the reservoir ( 12 ). The electromotor ( 16 ) drives the pump ( 14 ). The electromotor ( 16 ) is provided with a cooling jacket ( 28 ), which defines a cooling chamber ( 30 ). Fluid of the fluid circulation system flows through the cooling chamber ( 30 ).
