摘要： An expansion unit (4) for converting an expansion energy of pressure-increased steam into a rotation energy of an output shaft, wherein a cover member (26) is provided on the casing outer surface of the expansion unit (4). The cover member (26) has a function of sealing the end section of an output shaft (23) protruding beyond the casing outer surface against the outside and a function of recovering steam led out from the casing and has its pressured reduced after the conversion. The end section of the output shaft (23) provided inside the cover member (26) and a driven-side transmission shaft (119) disposed outside the cover member (26) are coupled with each other via a magnet type shaft coupling (120) so as to be able to transmit power, whereby the output shaft (23) and the driven-side transmission shaft (119) can be coupled without steam in the expansion unit leaking outside.

摘要： 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.

摘要： In a rotary fluid machine for converting the reciprocal movement of pistons and the rotational movement of a rotor from one into another by the engagement of rollers and annular grooves with each other, a value in a positive peak region of a pressure load of pistons received by the rollers engaged in the annular grooves and a value of a positive peak region of a centrifugal force load received by the rollers are set, so that they are substantially equal to each other, and phases of the two peak regions are deviated from each other. In addition, the phase negative peak region of a vane pushing-down load received by the rollers and the phase of the positive peak region of the pressure load of the pistons received by the rollers are established, so that they are overlapped at least partially on each other.

摘要： Pistons (41) are slidably received in a plurality of cylinders (39) disposed radially in a rotor (31), and a plurality of vanes (42) cooperating with the pistons (41) are disposed radially in the rotor (31), so that a vane chamber (54) is defined between a pair of the adjacent vanes (42). The radial movements of each of the pistons (41) and each of the vanes (42) are substantially stopped, so that the volumes of each of the cylinders (39) and each of the vane chambers (54) are not changed, for a period from the end of an exhaust stroke at which a gas-phase working medium is discharged from the cylinder (39) and the vane chamber (54) to the start of an intake stroke at which the supplying of the gas-phase working medium is started. Thus, it is possible to prevent the generation of a water hammer phenomenon due to a liquid-phase working medium confined in the cylinder (39) and the vane chamber (54).
