摘要： An integrated in-line electric motor/hydraulic pump that includes a pump housing having a pair of end members mounted at opposed ends of the housing. An electric motor includes a rotor on a shaft journalled between the end members and a stator surrounding the rotor within the housing. A pump inlet opens into the interior of the housing. First and second vane pump cartridges are integrated into one of the end members. Each vane pump cartridge includes a rotor coupled to the shaft, and a plurality of vane carried by the rotor to engage a vane cam ring that surrounds the rotor, which defines at least one pumping cavity between the cam ring and the rotor. A vane pump inlet passage within the one end member extends between and operatively couples the housing interior to the pumping cavities of both the first and second vane pump cartridges for feeding fluid from the housing interior to both cartridges in parallel. A vane pump discharge is also carried by the one end member and operatively coupled to both of the pumping cavities in parallel.
