Abstract:
Axial piston engine (1) having a housing (2), in the housing interior (4) of which a drive shaft (7) and, axially next to the latter, a cylinder drum (16) are rotatably supported, wherein the longitudinal center lines (9a, 9b) of the drive shaft (7) and of the cylinder drum (17) are inclined at an angle (W) relative to one another, wherein in the cylinder drum (16) a plurality of piston bores (18) extending approximately parallel to its center line (9b) are disposed, in which pistons (21) are guided so as to be displaceable axially to and fro, of which the piston ends facing the drive shaft (7) are connected in a universally pivotal manner by supporting joints (25) to the drive shaft (7), wherein a return disk (31) common to all supporting joints (23) is provided, which prevents axial removal of the piston ends from the supporting joints (23), and wherein a sensor (36) for determining the rotational speed of the drive shaft (7) is provided, which cooperates with markings (39) disposed so as to be distributed in peripheral direction on a component, which during functional operation rotates with the drive shaft (7),characterised in that the markings (39) are disposed in the peripheral region of the return disk (31).
