Hydrostatic axial piston machine e.g. swash plate type axial piston pump, has housing-side resistance parts arranged on inner wall of housing to influence pressurization in housing as result of volumetric flow

摘要

The machine has housing-side resistance parts (20a, 20b) i.e. rib-like components, arranged on an inner wall (8a) of a housing (8) to influence pressurization in the housing as a result of a volumetric flow. The volumetric flow is produced by change in volume of interstices of a piston (5) in a piston projection region during rotation of a cylinder block (3). The projection region is axially formed between a stroke disk i.e. swash plate, and a front end of the block containing a piston recess (4), and projected into a portion of the piston emerged from the recess.
