Title: Electric motor/radial pump assembly

Abstract: A motor-driven radial piston pump assembly has its radial piston pump supported by a base section on one side thereof which likewise supports an electric motor for powering the pump which is supported on that same side coaxially. The electric motor and a hydraulic tank are directly connected to the base section, the motor being surrounded by a cylindrical-shaped motor housing forming an inner wall of the tank and being sealingly connected to the base section, the motor housing being closed by a cover on its outer end opposite the pump. Such arrangement is compact in that the electric motor is simply positioned directly on the base section and is almost completely surrounded by the hydraulic tank such that the separate motor housing of the electric motor can be of simple and light weight construction.
