ABSTRACT:
An outer periphery of an output shaft integral with a rotor of an expander of a vane-type operated by a high-pressure vapor is supported at its opposite ends by a static-pressure bearing mounted at one end thereof in a floated state provided by a liquid film of a pressurized liquid-phase fluid supplied from a pressurized liquid-phase fluid feed bore through a pressurized liquid-phase fluid passage, and by a static-pressure bearing mounted at the other end thereof in a floated state provided by a liquid film of a pressurized liquid-phase fluid supplied from a pressurized liquid-phase fluid feed bore through pressurized liquid-phase fluid passages. Vanes supported radially in the rotor for reciprocal movement are supported in floated states by a liquid film of a pressurized liquid-phase fluid supplied through pressurized liquid-phase fluid passages extending radially outwards within the rotor.
