Abstract

Axial piston machine, capable of functioning as a pump or as a hydraulic motor, comprising a fixed envelope and a shaft for input or output of the drive, supported on it in the axial direction, and to which a block in which a series of cylinders have been made, parallel to the axis and equidistant from it, inside which corresponding pistons move, which are elastically urged to rest on a limb against an inclined disc fixed to the enclosure, so that in the movement of rotation of the block are forced to move along the corresponding cylinder, while the cylinders, during this movement, are in communication with slots of liquid inlet and outlet made in a fixed part to the envelope, characterized because the block of cylinders, through a coupling based on sections: fluted, can move freely in axial direction with with respect to the tree to which it is coupled in rotation, and in that each piston carries a sliding shoe joined thereto through a joint with a ball joint; the support surface of the shoe on the aforementioned inclined disc is provided with a closed cavity in all its periphery, which is in communication with the compression chamber of the cylinder through a corresponding passage through the joint and extends into axial direction along the plunger, so that the shaft and the cylinder block are not subjected to hydraulic stress of any kind.
