The invention relates to an axial piston engine (1) comprising a housing (2) wherein a cylinder drum (17) is arranged. Several axially extending piston bores (21) are embodied in the cylinder drum and arranged in such a way that they are distributed around the longitudinal center axis (7a) of the cylinder drum (17). Pistons (23) are moveably guided in said bores and are supported by sliding shoes (29) on a pivoting mounted on a transversely extending pivoting axis (27). A stop (44b) or a stop (44a, 44b) on both sides of the pivoting axis (27) is/are provided in order to limit the pivoting movements of the pivoting plate (26). In order to stabilize the axial piston engine and provide it with a simple design, the stop (44b) or both stops (44a, 44b) are arranged on a sleeve-like supporting element (45) which is supported by the inner covering surface (3c) of the inside of the housing (4).
Axial piston engine (1) having a housing (2), in the housing interior (4) of which a cylinder drum (17) is mounted, in which a plurality of approximately axially extending piston bores (21) are formed, which are arranged so as to be distributed around the longitudinal centre line (7a) of the cylinder drum (17) and in which pistons (23) are movably guided, which are supported via sliding pads (29) against a swivel plate (26) mounted so as to be capable of swivelling about a transversely extending swivelling axis (27), wherein one stop (44b) or one stop (44a, 44b) disposed on either side of the swivelling axis (27) is or are provided for limiting the swivelling motions of the swivel plate (26),
Axial piston engine according to one of the preceding claims,
Axial piston engine (1) having a housing (2), in the housing interior (4) of which a cylinder drum (17) is mounted, in which a plurality of approximately axially extending piston bores (21) are formed, which are arranged so as to be distributed around the longitudinal centre line (7a) of the cylinder drum (17) and in which pistons (23) are movably guided, which are supported via sliding pads (29) against an inclined surface (26a) of a swivel plate (26), and having disposed on the housing (2) a first retaining apparatus (51) with a supporting part (45) with a shoulder (53) for supporting a return apparatus (33) against the housing (2), wherein the shoulder (53) is disposed at the side of the axial piston engine (1) at which the pistons (23) execute an induction stroke, and wherein the shoulder (53) engages at an axial distance (a) behind the return apparatus (33) at the side facing the cylinder drum (17),
