Hydrostatic Positive Displacement Machine

摘要

A hydrostatic positive displacement machine has a cylinder drum (4) located in a housing (9) and rotatable around an axis of rotation (2). During rotation of the cylinder drum (4), a piston bore (5) is placed in alternating communication with an inlet side (E) and an outlet side (A). The inlet side (E) and outlet side (A) comprise connections (21; 22) to a control plate (12). A reversing device (30) is located in a reversing area (25; 26) between the connections (21,22) on the control plate (12). The reversing device (30) damps the pressure adjustment between a displacement chamber (V) and the pressure present in the connection (21; 22). The reversing device (30) includes at least two flow connections which are actuated simultaneously by the displacement chamber (V) as it moves along the reversing area (25; 26).

主权项

1. A hydrostatic positive displacement machine, comprising:
a cylinder drum located in a housing and rotatable around an axis of rotation, wherein the cylinder drum is provided with at least one piston bore; a longitudinally displaceable piston located in the piston bore, wherein during rotation of the cylinder drum the piston bore is placed in alternating communication with an inlet side and an outlet side, wherein the inlet side and outlet side comprise connections to a control plate; and a reversing device located in a reversing area between the connections on the control plate and which, by means of a volume flow into or out of a displacement chamber formed by the piston and the piston bore, damps a pressure adjustment between the displacement chamber and a pressure present in the connection, wherein the reversing device comprises at least two flow connections which are actuated simultaneously by the displacement chamber as it moves along the reversing area.
