Abstract: In a cylinder dividing mechanism of a pneumatic tool, the first and second air pressure driving spaces are formed in the chamber, the first and second external channels are set externally on the circumferential wall, the first external channel is connected with the first air intake and air intake/exhaust dividing controller, and the second external channel is connected with the second air intake and air intake/exhaust dividing controller. As such, a single chamber is provided with two air pressure driving spaces for synchronous compression and driving of the rotor. The driving torsion for the pneumatic tool could be multiplied without need of increasing the volume of the chamber of the cylinder to cater for the need of the users with improved applicability.

Abstract: A cylinder is installed within a case, and an output shaft and an arm that is integrated thereto and extends in a radial direction are installed within the cylinder. A piston extending in an arc slides and is displaced in a circumferential direction of the cylinder within the cylinder. One end portion of the piston is rotatably connected to the arm. The cylinder is internally provided with a first pressure chamber in which the arm is housed and a second pressure chamber in which the other end portion of the arm is slidably installed. A pressure medium is fed into one of the first and second pressure chambers and discharged from the other, and the output shaft pivots in a rotational direction.

Abstract: Two rotary mechanism parts (70, 80) are provided in a rotary expander (60). The first rotary mechanism part (70) is smaller in displacement volume than the second rotary mechanism part (80). A first low-pressure chamber (74) of the first rotary mechanism part (70) and a second high-pressure chamber (83) of the second rotary mechanism part (80) are fluidly connected together by a communicating passageway (64), thereby forming a single expansion chamber (66). High-pressure refrigerant introduced into the first rotary mechanism part (70) expands in the expansion chamber (66). An injection passageway (37) is fluidly connected to the communicating passageway (64). When an motor-operated valve (90) is placed in the open state, high-pressure refrigerant is introduced into the expansion chamber (66) also from the injection passageway (37). This makes it possible to inhibit the drop in power recovery efficiency, even in the condition that causes the actual expansion ratio to fall below the design expansion ratio.

Abstract: An adjustable rotary vane pump for changing the direction and rate of fluid flow through the pump. The pump comprises a first pump housing having a generally cylindrical chamber therein along a central axis of the housing. A second housing is provided having a second chamber therein coaxially oriented with the first housing. An insert member is provided in the second housing having an aperture therein of a given eccentricity. The insert member is slidably adjustable for rotational movement within the second housing for providing varying cross-sectional dimensions for the fluid flow through the pump. A rotor is disposed in the housing coaxial with the first and second housing. A plurality of vane members are provided on the rotor which respectively engage the walls of the first chamber and the insert member within the pump.

Abstract: The present invention describes an external combustion rotary engine, which, due to the separate combustion chamber of the engine, is possible the operation at a lower temperature than those internal combustions, therefore, the engine efficiency is greater. Another characteristic presented by the external combustion rotary engine is that it has concentric expansion chambers and through cams that have a rotor, it is possible to take advantage of the expansion force of the working fluid. The external combustion rotary engine is of closed-cycle operation, so the consumption of additional water is reduced as work fluid since the amount of water within the system is sufficient. Finally, it is worth mentioning that the external combustion rotary engine, thanks to its operation principle, can be applied in the electric power generation field.

Abstract: A multi-stage expansion device having bypass capabilities and a variable speed drive is disclosed. In one example, the multi-stage expansion device has a housing within which a first stage, a second stage, and a third stage are housed. The housing may also be configured with internal working fluid passageways to direct a working fluid from the first stage to the second stage and/or from the second stage to the third stage. Each of the stages may include a pair of non-contacting rotors that are mechanically connected to each other and to a power output device such that energy extracted from the working fluid is converted to mechanical work at the output device. In one example, a bypass line is provided to bypass working fluid around the first stage and a bypass line is provided to bypass working fluid around the second stage.
