A rotor comprises two rotor sections mounted coaxially on a shaft for limited axial movement relative to each other. The two sections are slightly spaced axially from each other and one defines a peripheral porting surface engaging a second porting surface defined by a porting member. The rotor has a plurality of bores each carrying a piston and including a first portion defined by one of the rotor sections, a second portion defined by the other of the rotor sections, and an intermediate portion extending between the rotor sections. The pistons engage a cam comprising a sheet pressed into a configuration including a plurality of coaxial annular sheet portions. One sheet portion defines the undulating cam surface; two other sheet portions extend parallel to each other and perpendicular to the one portion from the opposite sides of the one portion.
In a rotary fluid device of the type including a shaft, a cam defining an undulating cam surface, a rotor mounted coaxially of the shaft and defining a porting surface, a plurality of pistons engaging the cam carried by the rotor for movement relative thereto, a porting member defining an annular porting surface engaging the rotor porting surface, and a plurality of bores defined by said rotor and each carrying at least one of said pistons, that improvement wherein:
