Title:

ROTARY FLUID MACHINERY

Document Type and Number:

WIPO Patent Application WO/2003/027441

Kind Code:

A1

Abstract:

Rotary fluid machinery, comprising a rotor chamber (14), a rotor (41) stored in the rotor chamber (14), a vane (48) guided by a vane groove formed in the rotor (41), and a piston (47) slidably fitted to a cylinder (44) installed in the rotor (41), wherein hot water in a static pressure bearing for supporting the vane (48) in the vane groove in floated state is held in a plurality of pockets (48f) recessedly provided in the surface of the vane (48) and supplied to the rotor chamber (14) in an expansion stroke by the outer radial movement of the vane (48) according to the rotation of the rotor (41), and the hot water supplied to the rotor chamber (14) is evaporated into vapor, whereby the performance of the rotary fluid machinery can be increased by the pressure energy of the vapor.
