Abstract

A multiple stage rotary fluid device enclosed within a housing containing a working hydraulic fluid. An axially extending shaft is adapted to be secured to a source of power at one end. Fluid within the housing is directed across a control valve to an initial pump stage driven by the shaft. Pressurized fluid from the initial pump stage is directed to a hydraulic motor having a rotor which is rotatably driven through a planetary gear arrangement within an accentric housing. The pump housing surrounding the motor and pump is driven in a direction opposite that of the main shaft through a bevel gear arrangement driven from the axial shaft. Fluid is discharged through peripheral exhaust ports and the reservoir.
