Axial Piston Machine Having an Inclined-Axis Construction

Abstract

An axial piston unit ( 1 ) having bent-axis construction with several guided piston elements ( 3 ) longitudinally movable in one rotatable cylinder device ( 2 ) and with an area ( 4 ) operatively connected with the piston elements ( 3 ) and guided with torque. The torque-guided area ( 4 ) is constructed to be rotatable around a swivel axis ( 10 ), and a displacement of the axial piston unit ( 1 ) varies depending on the rotary movement of the torque-guided area ( 4 ).
