Abstract
An axial piston machine in a slanted axis design with constant displacement volume is disclosed. A tapping opening is arranged in the first reversing region, which can be brought into fluid exchange connection with one of the openings in each case by rotating the cylinder drum. The tapping opening is permanently connected to a pre-compression chamber via a connection channel, which runs completely in the housing. The pre-compression chamber is formed closed with the exception of the connection channel, wherein it is arranged completely in the housing.
Claims12
An axial piston machine, comprising:
- a housing, wherein an adapted control surface is fixedly arranged on the housing;
- a drive shaft rotatably mounted in the housing with respect to a first axis of rotation;
- a cylinder drum having a counter-control surface that slidably abuts the adapted control surface, wherein the adapted control surface is non-planar and rotationally symmetrical with respect to a second axis of rotation, and wherein the first and second axis of rotation are arranged inclined relative to each other at a fixed angle of inclination other than zero;
- a plurality of working pistons received in the cylinder drum in a linearly movable manner such that together with the cylinder drum they each limit a working area, wherein the working pistons are each motion-coupled to the drive shaft via a ball joint arranged at distance to the first and the second axis of rotation;
- and
- a first and a second working connection arranged on the housing, which are each permanently fluidically connected to an associated first or second control kidney on the adapted control surface,
- wherein each working area opens with an opening on the counter-control surface, and wherein said openings are each configured to be brought into fluid exchange connection with the first or the second control kidney by rotating the cylinder drum, and further wherein the first and second control kidneys are spaced apart from one another in the circumferential direction with respect to the second axis of rotation via a first and a second reversing region, and
- wherein a tapping opening is arranged in the first reversing region which is configured to be brought into fluid exchange connection with one of the openings in each case by rotating the cylinder drum, and wherein the tapping opening is permanently connected to a pre-compression chamber via a connection channel which runs completely in the housing, and wherein the pre-compression chamber is formed closed with the exception of the connection channel, and wherein it is arranged completely in the housing.
