Abstract
A reservoir apparatus for an electronically controlled electric pump includes a pump housing (22), constructed of thermally conductive material, the pump housing having a cup-shaped reservoir portion (160) adapted to surround a pump assembly (164) to maintain the pump assembly submerged in hydraulic fluid (162). The pump housing also includes a fluid inlet (166) and a fluid outlet (168) for communicating fluid from the pump assembly to a hydraulically actuated device, such as a steering gear. The pump housing (22) also includes a first module member portion (20) adapted to seal with a second module member (24) so as to form a control module. The first module member portion (20) being operative to transmit thermal energy from electronic components into the pump housing and the hydraulic fluid.
