Hydraulic transformer for hydrostatic drive system, has set of displacement bodies guided in rotor and designed as radial pistons, where pressurizing medium inflow and - outflow take place at spaces by rotor axle

摘要

The transformer (18) has a displacement body area (44) connected during rotation of a rotor (76) with a motor-sided inlet channel (62), motor-sided drain channel (64), pump-sided pump inlet channel (66) and a pump-sided drain channel. A set of displacement bodies (40) is guided in the rotor and designed as radial pistons, where pressurizing medium inflow and - outflow take place at spaces (54, 56, 58, 60) by a rotor axle (43). The inlet channel, drain channel, pump inlet channel and a consumer channel (68) are arranged in the axle. End sections of the bodies are supported at a cam ring (38).
