| Summary: | An outer periphery of an output shaft (
23
) integral with a rotor (
31
) of an expander of a vane-type operated by a high-pressure vapor is supported at its opposite ends by a static-pressure bearing (
25
) 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 (
129
) through a pressurized liquid-phase fluid passage (W
5
), and by a static-pressure bearing (
25
) 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 (
129
) through pressurized liquid-phase fluid passages (W
6
, W
7
, W
9
, W
10
. W
11
and W
12
). Vanes (
42
) supported radially in the rotor (
31
) 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 (W
14
) extending radially outwards within the rotor (
31
). Thus, various sliding portions of a rotary fluid machine such as an expander of a vane-type can be lubricated effectively. |
