The invention relates to an axial piston engine (1) comprising a housing (2) and a cylinder drum (5) that is pivotably arranged in one interior space (3) of the housing. Several cylinder bores (6) are embodied in said cylinder drum (5). Pistons (7) are moveably guided in said cylinder bores (6) and rest on a swash plate (11) by means of guide shoes (8). The axial piston engine (1) also comprises a retracting device (15). The guide shoes (8) rest on the retracting device (15) when the pistons (7) are retracted. A restraint system (16) is accommodated in the housing (2), can be moved against a spring (40) and is used for supporting the retracting device (15) at the housing (2). The aim of the invention is to improve and stabilise the support of the retracting device (15). To this end, the retracting device (15) is supported by a support device (16a) which is situated behind the retracting device (15) at the side facing away from the swash plate (11). The support device is connected to the swash plate (11). The restraint system (16) supports the back of an essentially radial locating face (11a) at the swash plate (11) or an add-on piece thereof when the restraint system (16) is pushed into the interior space (3) of the housing.
Axial piston machine (1) with a housing (2), with a cylinder drum (5) which is arranged to be rotatable in a housing interior space (3) and in which there are formed a plurality of cylinder bores (6) in which pistons (7) are movably guided, which pistons are supported on a swash plate (11) via slide shoes (8), with a retracting device (15) on which the slide shoes (8) are supported during the retracting movement of the pistons (7), and with a restraint device (16) which is mounted in the housing (2) and is movable against a spring (40) and the purpose of which is to support the retracting device (15) on the housing (2), characterised in that the retracting device (15) has engaging therebehind, on its side facing away from the swash plate (11), a supporting device (16a) connected to the swash plate (11), wherein there is provision, between the supporting device (16a) and the retracting device (15), for an axial spacing (a) which is dimensioned to be of such a size that, when the axial piston machine (1) is in operation, the retracting device (15) abuts against the supporting device (16a) before the retracting device (15) is deformed beyond its elastic deformation limit, and the restraint device (16), in the working position thereof pushed into the housing interior space (3), engages behind a substantially radial locating face (11a) on the swash plate (11) or an add-on piece thereof.
