Abstract (en)
[origin: WO2014094024A1] The invention relates to a bent-axis machine (1), comprising a housing (2) having a control cover (9) and a piston drum (4) which is rotatably mounted in the housing (2) on a valve plate (3) and which has axial cylinders (5), of which each cylinder (5) receives a piston (6). Said bent-axis machine also comprises a drive flange (8) which is associated with a drive shaft (7) and on which the free ends of the pistons (6) projecting out of the cylinders (5) are supported, and having an adjustment system comprising a pivot cradle for adjusting the displacement volume and having an actuating drive (10), by means of which the piston drum (10) together with the valve plate (3) can be pivoted relative to the drive axis (T) about a maximum working range which is delimited by a minimum pivot angle (αmin) and a maximum pivot angle (αmax). A hydraulic fluid flows over the pivot cradle through the valve plate (3). The invention is characterised in that the minimum pivot angle (αmin) of the working range is shifted out of its zero position by at least 5°, preferably by at least 7°, wherein the maximum pivot angle (αmax) is extended in the same way by at least 5°, preferably by at least 7°, in order to retain the entire working range about the region recessed in the lower region.
