ABSTRACT:
An axial piston machine has a cylinder barrel mounted on a shaft and rotatable with respect to a portion of the casing. Between the cylinder block and the casing portion is a disc. The side of the disc adjacent the casing portion is concave and abutting casing portion is correspondingly convex. The disc is restrained against rotation and forms part of the valving means for the cylinder barrel. In one embodiment the casing and shaft are in two articulated sections. The shaft sections lie in a common plane and are pivotable with respect to each other about a point and the casing sections are pivotable about an axis normal to that plane and offset with respect to the shaft pivot point. In another embodiment the casing and shaft are each a single unit.
