Axialpiston machine

Abstract

Axial piston machine comprising a drive shaft, a drive mechanism that is connected thereto for conjoint rotation and comprises one or more drive-mechanism pistons, the piston stroke of which can be set by a swash plate, at least one return spring acting on the swash plate and a setting piston supporting on the swash plate, the axial piston machine comprising at least one control or regulating valve or at least one control or regulating unit, characterized in that a setting piston is guided in the connecting plate and a setting lever acts as a coupling member between the setting piston and the swash plate and the setting-piston axis and the setting-lever axis are positioned in a plane E1, in particular in a half plane E1* extending from the drive-shaft axis M.

1 . Axial piston machine comprising a drive shaft, a drive mechanism that is connected thereto for conjoint rotation and comprises one or more drive-mechanism pistons, a piston stroke of which can be set by a swash plate, wherein at least one return spring acts on the swash plate and a setting piston is supported on the swash plate, wherein the axial piston machine comprises at least one control or regulating valve or at least one control or regulating unit, wherein
 a setting piston is guided in a connecting plate and a setting lever acts as a coupling member between the setting piston and the swash plate and a setting-piston axis and a setting-lever axis are positioned in a plane.   
     
     
         2 . Axial piston machine according to  claim 1 , wherein the setting-lever axis are positioned in a plane, the plane being a half plane extending from a drive-shaft axis, and wherein the setting-piston axis extends in parallel with the drive-shaft axis and the setting-lever axis is positioned in the plane. 
     
     
         3 . Axial piston machine according to  claim 2 , wherein the setting lever allows for approximately parallel functional positions relative to the drive-shaft axis and/or approximately coaxial functional positions relative to the setting-piston axis, wherein an angular deviation from the relevant axis of less than 3° is made possible. 
     
     
         4 . Axial piston machine according to  claim 3 , wherein an extension of a central axis of the at least one return spring is positioned in the plane. 
     
     
         5 . Axial piston machine according to  claim 4 , wherein the half plane extends centrally or almost centrally with respect to a swash-plate mount. 
     
     
         6 . Axial piston machine according to  claim 2 , wherein a control or regulating valve is in the connecting plate, wherein the axis of said control or regulating valve is positioned in the half plane and the axis of said control or regulating valve is arranged in parallel with the drive shaft. 
     
     
         7 . Axial piston machine according to  claim 2 , wherein at least one control or regulating unit is arranged on the connecting plate, wherein an axis of the control or regulating unit extends approximately at right angles to the half plane. 
     
     
         8 . Axial piston machine according to  claim 7 , wherein a plurality of the control or regulating units are arranged on the connecting plate, wherein each axis of such control or regulating unit extends either approximately at right angles to the half plane or approximately in parallel with the half plane. 
     
     
         9 . Axial piston machine according to  claim 6 , wherein each axis of the control or regulating valves installed in the connecting plate is approximately at right angles to at least one axis of a control or regulating unit arranged on the connecting plate.
