In axial piston machines, at least one working piston is mounted in a longitudinally displaceable manner in a cylinder bore of a piston drum and forms a cylinder space with the cylinder bore. The cylinder space is alternately compressed and decompressed by the longitudinal movement of the working piston and, accordingly, alternately connected to a high-pressure reservoir and a low-pressure reservoir. When changing from the low-pressure reservoir connection to the high-pressure reservoir connection, pulsations occur which can result in substantial noise generation. To counteract this, so-called pre-compression volumes are used, which are formed by pre-compression spaces.
Axial piston machines having pre-compression spaces or zones are known from, the prior art, for example from DE 197 06 114 C5. In this, a pre-compression volume or a reservoir element is integrated in a control plate or in a connection plate of the axial piston machine. The pre-compression volumes known from the prior art can additionally be controlled via valve devices.
The known pre-compression spaces are sealed or closed outside the housing of the axial piston machine, which requires additional installation space. With regard to automobile applications, the installation space is an increasingly important issue for axial piston machines.
The seal of the pre-compression spaces moreover poses a technical challenge owing to the pulsation.
The object of the disclosure is to reduce the installation space for creating pre-compression spaces.
