Machine driven by pressurized fluid has step surfaces joining outflow and baffle sections defining relatively small free volumes, outlet device with outlet opening(S) from buffer volume

摘要

The machine has a rotor (12) in a housing (14) with at least one inlet nozzle (28) for subjecting the rotor to pressurized fluid and an outlet device for the fluid. The rotor has inwardly curved baffle sections (18) for the pressurized liquid directed approximately tangentially to the baffle curves, which join onto approximately axis-parallel outflow sections. Step surfaces (30) joining the outflow and baffle section defined relatively small free vol. (32). The axial rotor length is less than the housing length to form a buffer vol. and the outlet device has at least one outlet opening from the buffer vol.
