ELECTRIC MOTOR DRIVEN HYDRAULIC APPARATUS WITH AN INTEGRATED PUMP Abstract of the Disclosure An electric motor driven inline hydraulic apparatus comprising a housing having end members closing said housing, an electric motor stator mounted in said housing, an electric motor rotor, a shaft on which the rotor is mounted is journalled in the housing and a pump is integrally formed on one or both of the end members. The shaft extends through an opening in the end member and is connected to the rotating group of the pump. Hydraulic fluid is supplied to the interior of the electric motor housing and flows through passages in the housing to the intake of the pump integral with the end member. The end member associated with the pump is formed with an enlarged chamber adjacent the inlet of the pump which functions to reduce the flow velocity and separate the contained air from the hydraulic fluid thereby reducing the operating sound level of the pump.
