AXIAL PISTON PUMP

摘要

The periodic axial movement of the rotary piston (6) is performed by a cam mechanism which has a cam surface (8) rotating around the piston axis and a cam follower (9) that is in functional connection with the cam holder. The relative position of the cam holder determines the piston stroke in the course of one revolution. In this arrangement, the drive shaft (5) can extend coaxially with the piston (6). In a particularly advantageous manner, the follower is pressed against the cam holder under spring pre-tension.
