A hydrostatic unit, comprising:
- a hydraulic machine mounted pivotably and connected via at least one inlet flow path and one outlet flow path to a rotatable connection side of a rotary leadthrough, the connection of which is mounted in a rotationally fixed manner and is in pressure medium connection with a pressure medium source and a pressure medium sink;
- and
- an adapter piece having (i) a connection flange configured to attach to the rotatable connection side of the rotary leadthrough and (ii) a motor connection region configured to indirectly or directly attach to a housing of the hydraulic machine, the inlet flow path and the outlet flow path being formed substantially in the adapter piece and opening into the connection flange on one side and into the motor connection region on the other side.
An adapter piece for a hydrostatic unit including a pivotably mounted hydraulic machine, comprising:
- a connection flange configured to mechanically and hydraulically connect to a rotary leadthrough;
- and
- a motor flange configured to mechanically and hydraulically connect to a housing part of the hydraulic machine or a connection plate of the hydraulic machine, the adapter piece defining at least one inlet duct and one outlet duct that open into the respective flanges.
