Swash-plate machine for use as e.g. axial piston pump of drive train of motor vehicle, has pivot unit that pivots swivel cradle and low-pressure opening for input and/or discharging hydraulic fluid into and/or out of piston bores

摘要

The machine (1) has a cylinder or rotary drum (5) that is mounted about a rotation axis (8) with piston bores (6) and a piston (7) that is movably mounted in piston bores. A swivel cradle (14) is pivotally mounted about a pivot axis (15) and a cradle bearing (20) pivots the cradle. A pivot unit (24) pivots the swivel cradle and a low-pressure opening is provided for input and/or discharging hydraulic fluid into and/or out of rotating piston bores. A high-pressure port is provided for removal and/or introduction of hydraulic fluid from and/or to rotating piston bores. An independent claim is included for a drive train.
