Radial piston machine with shaft radial position stroke control

摘要

A hydraulic radial piston machine with steplessly adjustable volumetric displacement and piston stroke has a bank of pistons with axes in a common plane transverse to the shaft and machine axes. A radially displaceable supporting member pivotably connected to a shaft longitudinal portion turnable from the machine longitudinal axis supports the pistons. The longitudinal portion is pivotably connected at one end to a further longitudinal shaft portion. The second end connects to a turning link transmission which rotates. Rotation of the first-mentioned longitudinal shaft portion causes the supporting member to travel a circular path around the machine axis. A force-loaded translating operating displacing member steplessly varies the diameter of this circle to steplessly adjust piston stroke.
