- sealing element can be required only a portion of the
- Fluid change openings which are assigned to the one or the working cylinder exporting cylinders comprises, are covered by using a sufficiently high contact pressure by means of the rotary valve and concretely by means of the sealing element of the rotary valve, while for the non-formed by the sealing element

- Rotary valve relative to the cylinder head plate can be kept low. This is especially true if, as is preferably provided, the main body of the
- Rotary valve is arranged at least partially and preferably completely spaced from the cylinder head plate, so that it can be provided that only the sealing element comes into direct contact with the cylinder head plate, whereby the portion of the underside of the rotary valve, which is not formed by the sealing element, not only not under a high pressure against the
- Cylinder head plate is pressed, but preferably not contacted at all.
- An inventive axial piston motor is preferably according to the
- the swash plate is rotatably mounted on a swash plate, wherein the support surface of the swash plate and thus the orientation of the swash plate are aligned obliquely with respect to the longitudinal axes of the cylinder.

- the force with which the sealing element 70 is pressed against the cylinder head plate 40 directly dependent on the height of the inlet pressure of the fluid, so that at each actual provided in the operation of the axial piston 10 height of the inlet pressure on the one hand achieves a sufficient seal and on the other hand unnecessary strong pressing of the sealing element 70 to the cylinder head plate 40 and thus an unnecessarily high
- Cylinder head plate 40 is avoided.
- this closed section of the sealing element 70 upstream of the inlet opening 54 By varying the length of this closed section of the sealing element 70 upstream of the inlet opening 54, precompression of fluid still remaining in the cylinders 16 can be realized and adapted by this section of the sealing element 70 already covering the fluid change openings 42 before the associated pistons 18 have their OT have reached.
- a pressure piston 74 is provided immediately behind (with respect to the direction of rotation 72) of the inlet opening 54, which is followed by a plurality of further pressure piston 74. It is provided that on the one hand, the surfaces of the inlet pressure of the fluid exposed upper surfaces of the pressure piston 74 are formed in the direction of rotation 72 becoming larger and on the other hand, the distances between the plunger 74 are formed smaller in the direction of rotation, whereby a particularly strong pressing of the sealing element 70 to the Cylinder head plate 40 in a the
- Entrance opening 54 comprehensive range is achieved while the contact pressure with increasing distance from the inlet opening 54 is smaller, whereby the pressure generated by the individual pressure piston 74 and acting on different areas of the sealing element 70 pressing forces on the during the working cycles in the cylinders 16 increasingly reducing fluid pressure is adjusted.
- Taumelinfußes 24 is taken, is provided, this against a
- the locking sleeve 82 is provided, which is connected to the cylinder housing 12.
- the locking sleeve 82 is also connected via a cardan-like joint arrangement with the swash plate 22.
- the joint arrangement rotatably binds the swash plate 22 to the locking sleeve 82 and thus to the cylinder housing 12 and at the same time allows the tumbling movement of the swash plate 22.
- the hinge assembly comprises a hinge ring 84 which extends about a respective first axis about each of two bearing pins 86 is rotatably connected to the locking sleeve 82 and about a second, perpendicular to the first axis extending axis rotatably connected to the swash plate 22.
- the axial piston motor 10 can be used, for example, in a cycle device 88 for utilizing waste heat of an internal combustion engine 90 of an internal combustion engine of a motor vehicle (compare FIG. 10).
- a vaporized and superheated and pressurized fluid expands in the axial piston motor 10, whereby a part of the thermal and potential energy of the fluid in mechanical energy or power (P me c h ) is converted.
- the fluid is conveyed in the liquid state by means of a pump 92 (conveying device) to an evaporator 94 in which it is heated by the transfer of heat energy from exhaust gas discharged from the internal combustion engine 90 via an exhaust gas line which integrates the evaporator 94.
- the thus vaporized and superheated fluid then flows to the
- Circuit processing device 88 In the condenser 34, the fluid is passed through a
- Heat transfer to a cooling medium for example, in a the one
- Internal combustion engine 90 integrated cooling system of the motor vehicle flowing coolant, cooled.
- the fluid condenses, so that it can be re-supplied to the evaporator 94 in the liquid state by means of the pump 92. Due to the
- the liquid fluid is pumped by means of the pump 92 and compression of the fluid present in the gaseous state between the evaporator 94 and the axial piston motor 10 (expander) is also achieved to an intended operating pressure, the pressure being generated by the pump 92 interacting with the expansion of the gaseous fluid in the axial piston 10 is.
- State point c there is a (theoretically) isobaric heat supply with evaporation and overheating. From the state point b 'begins the evaporation, the at
- the aim of the consideration in the TS diagram is a maximization of the supplied heat from the state point b to the state point c and a reduction of the dissipated heat (q_ab) from the state point d to the state point a.
- the enclosed area from the state point a via the state points b and c to the state point d should be maximized in the intended temperature range.
