摘要： A pump is comprised of a housing within which a rotary piston is rotatably mounted, to define therebetween an annular conveying channel between an inlet port and an outlet port. Annular sealing rings between the piston and housing seal the conveying channel at the periphery of the piston. A stopper extends into the conveying channel in the back flow path, and sealing elements are provided to seal the entire cross section of the back flow paths. Radially movable slides on the piston are resiliently urged into the conveying channel, the radial position thereof being controlled by a cam surface in the housing. The slides are urged radially outwardly by springs, and seals are provided on the piston for sealingly guiding the piston in the radial direction.

摘要： A concentric rotary fluid machine includes a first body and a second body that are rotatable relative to each other and coaxially arranged one inside the other. A plurality of gates are supported by the second body in gate pockets. Each gate pocket includes: a gate retention recess that receives a gate cylinder of a gate; a gate seal recess that receives a sealing portion of a gate; and an intervening land. The sealing portion is configured to reciprocate up and down within a corresponding gate seal recess while maintaining contact with the recess and the second body. A plurality of lobes on the first body cause the gates to swing about respective swing axes as the first body rotates relative to the second body. The lobes and the lands are configured so that a lobe forms a substantial seal against a land when in mutual radial alignment.

摘要： A compressor is provided that includes a stator, a cylinder type rotor rotated within the stator by a rotating electromagnetic field of the stator and that defines a compression chamber inside, a roller that rotates within the compression chamber of the cylinder type rotor by a rotational force transferred from the rotor and compresses a refrigerant during rotation, a rotational shaft integrally formed with the roller and that protrudes from one side of the roller in an axial direction, a vane that divides the compression chamber into a suction region and a compression region, and transfers the rotational force from the cylinder type rotor to the roller, and a shaft cover and a cover joined to the cylinder type rotor in an axial direction that form the compression chamber in which the refrigerant is compressed. The shaft cover includes a suction port through which the refrigerant is sucked, and the cover receives the rotational shaft therethrough.

摘要： A planetary rotation machine including at least one ring channel which is curved along an at least partial arc and that contains a piston that can be moved in a fluid generating a movement. The piston can be coupled to a rotary body coaxially arranged by a lever by the rotational axis thereof. A stable structure able to transmit high torques is obtained by guiding the lever through a gap created in the wall of the ring channel in a direction of displacement of the piston, in a radial direction away from the piston in a sealed manner.
