ABSTRACT:
A servo pump for use in a hydraulic system. The servo pump is constituted by a variable displacement type hydraulic pump adapted to be driven by a high-speed motor and to hydraulically drive an actuator. The motor and the pump are housed in a common casing. The motor shaft and the pump shaft are integrated to form a common rotary shaft which is supported rotatably at both its ends by end bearings and at its intermediate portion by an intermediate bearing.
