    摘要: The present invention provides a gas passage switching structure for a pneumatic rotary hand tool comprising a pneumatic motor and a revolving valve disposed in a device case. The pneumatic motor has an input ending surface. A forward gas inlet and a reverse gas inlet are formed and spaced apart on the input ending surface. The revolving valve has a gas supply surface. A gas supply port and a discharge port are formed and spaced apart on the gas supply surface. The gas supply surface and the input ending surface are arranged along an axis line in the device case adjacent or in contact with the arrangement so that it allows the pneumatic motor to drive the forward and reverse rotation by the high pressure air flow along the fluid passage in the axis line direction, thereby solving the problem saying the internal gas structure of the traditional pneumatic rotary hand tool is too complex.

    摘要: A pneumatic engine includes first and second pneumatic motors. Each motor has a stator, a rotor, and a gas flow path. The rotor is rotatably connected to the stator. The gas flow path is defined at least in part by the stator and the rotor, and extends from a gas inlet to a terminal gas outlet. The gas flow path has an expansion portion extending between the gas inlet and an intermediate gas outlet, and a compression portion extending between the intermediate gas outlet and the terminal gas outlet. The terminal gas outlet of the first pneumatic motor is fluidly connected upstream of the gas inlet of the second pneumatic motor.

    摘要: An energy-saving device with functions of air feeding and power generation includes an air feeder, an actuator unit, an air-operated device, a generator, and a power storage unit. The actuator unit includes a mounting base, a cylindrical body received in the mounting base, and an axle body rotatably received in the cylindrical body. The mounting base is connected to the air feeder through an air duct for introduction of gases from the air feeder to the cylindrical body. When the air feeder is activated, the axle body of the actuator unit is rotated to supply high-pressure gases to the air-operated device and simultaneously drive the generator to generate electricity, which is stored in the power storage unit for the air-operated device and/or a power-consuming end, for fullest use of electricity and energy sufficiency.

    摘要: A hydraulic device can include two or more rings, a rotor having a plurality of vanes, and an adjuster. The two or more rings can be rotatably mounted within the hydraulic device and arranged adjacent one another configured for relative rotation with respect to one another. The rotor can be disposed for rotation about an axis within the two or more rings and can have a plurality of circumferentially spaced slots, each slot having at least one of the plurality of vanes located therein. The plurality of vanes can be configured to be movable between a retracted position and an extended position where the plurality of vanes work a hydraulic fluid introduced adjacent to the rotor. The adjuster can be configured to translate linearly to rotatably position the two or more rings relative to one another to increase or decrease a displacement of the hydraulic fluid between the rotor and the two or more rings.

    摘要: A vane pump includes a rotor, vanes, pump chambers, a suction port, and a discharge port. The side member has a first transition section and a second transition section. The first transition section is a section from an end point of the suction port to a start point of the discharge port. The second transition section is a section from an end point of the discharge port to a start point of the suction port. An angle between the start point and the end point of the suction port is set such that a pressurizing timing is offset from a depressurizing timing. The pressurizing timing is a timing at which one pump chamber starts to communicate with the discharge port from the first transition section, and the depressurizing timing is a timing at which another pump chamber starts to communicate with the suction port from the second transition section.

    摘要: There is provided a free rotary fluid machine including: a main body which is provided in a hollow cylindrical shape, and has an elliptical inner circumferential surface; a rotor which is provided in the main body, and rotates about the same rotation center as the main body; tip seals which are provided at one side of the rotor so as to be in contact with the inner circumferential surface of the main body; and blades which are provided between the tip seals provided adjacent to each other, and supported by the tip seals, in which the blade has one end surface that faces the inner circumferential surface of the main body, and the other end surface that is opposite to one end surface, and centers of radii of curvature of one end surface and the other end surface are positioned at the same side. As described above, a space formed among the inner circumferential surface of the main body, the rotor, and the tip seal is sealed by the auxiliary tip seal, and as a result, it is possible to reduce friction between the tip seal and the main body and to prevent a leak of an introduced working fluid.
