Hydrostatic Rotary Machine Having Pins That Engage Grooves of a Cam Ring

A hydrostatic rotary machine comprising:

• a stator comprising a cam track;
• a rotor, the stator and the rotor being coaxial with respect to an axis of rotation and rotatable relative to one another;
• a plurality of pistons linearly movably received in the rotor such that, together with the rotor, the plurality of pistons delimit a respective associated cylinder space, the plurality of pistons configured to interact with the cam track in such a way that rotational movement of the rotor is associated with a stroke movement of the pistons,
• a separate cam ring on which the cam track is arranged, the cam ring being received in a main body of the stator so as to surround the rotor
• at least one pin fixedly received in a respective associated first recess in the main body, the at least one pin engaging in an adapted second recess, which is arranged radially outside on the cam ring,
• wherein the cam ring has a first end face and a second end face, which point in opposite directions with respect to the axis of rotation,
• wherein the second recesses are each configured as a groove extending in a direction of the axis of rotation, and
• wherein all of the grooves are open towards the first end face and open radially outward with respect to the axis of rotation.
