摘要： A scroll assembly includes an orbiting scroll and a cross ring. The orbiting scroll is configured to have a bottom plate. A plurality of bayonets and two positioning slots are provided on the outer peripheral surface of the bottom plate. The bayonets are adapted to be clamped by a chuck of a turning tool. The two positioning slots are arranged centrally symmetrically relative to the center of the orbiting scroll. Each of the positioning slots comprises two radial vertical surfaces, a circumferential vertical surface and an opening facing outwards in the radial direction. The cross ring is configured to have an annular body and two positioning pins. The lower surface of the bottom plate is slidably fitted on the upper surface of the annular body, each of the positioning pins is inserted into a corresponding positioning slot, and the positioning pins can slide back and forth relative to the positioning slot, so that the orbiting scroll can slide back and forth relative to the cross ring in the radial direction of the orbiting scroll. An annular groove adapted for being formed by turning is provided on the lower surface of the bottom plate of the orbiting scroll, and a chamfer is formed on the edge of the annular groove formed by the intersection of the circumferential vertical surface of the positioning groove and the lower surface of the bottom plate.

摘要： The invention relates to a vane pump for conveying liquids, in particular viscous oils, which vane pump includes: a rotor having sliding slots in which movable vanes are held and can be countersunk in relation to a rotor radius (r); a pump housing including a pump chamber, which encloses the rotor; and an inlet and an outlet, which open into the pump chamber at at least one end face of the rotor; radial elevations protruding, with respect to the sliding slots, over the circumference of the rotor, which elevations form a rotor radius (r) on either side of the vanes that can be countersunk, and radial pockets being recessed, relative to the rotor radius (r), between the radial elevations. Within the radial elevations, recesses are formed on the at least one end face of the rotor at which the inlet and the outlet open, which recesses provide rotating anticipatory control geometry for reducing pressure spikes in the vane cells.

摘要： A pump apparatus includes a pump chamber having a fluid inlet and a fluid outlet and a flexible impeller mounted for rotation within the pump chamber. The flexible impeller includes a plurality of radially extending vanes to contact a curved wall of the pump chamber, such that separate pump cavities are defined between adjacent vanes and the pump chamber wall. The fluid inlet and the fluid outlet are defined in the second end wall so that the curved pump chamber wall is uninterrupted.

摘要： A fluid pump includes a pump element in communication with an inlet and an outlet. Rotation of the pump element generates a suction at the inlet and pressure at the outlet. The suction and pressure cooperate to move a fluid through a fluid path. An accessory fluid path is in communication with the inlet and outlet. The accessory fluid path includes a thermistor in communication with the accessory fluid path. The thermistor monitors a temperature of the fluid within the accessory fluid path.

摘要： A crankshaft assembly, a compressor and a refrigeration device are provided. The crankshaft assembly has an eccentric shaft component, a spindle component and a main screw oil pump. The eccentric shaft component has an eccentric cavity, and the spindle component has a first cavity communicated with the eccentric cavity. A first through-hole and a second through-hole in a first spindle are each communicated with the first cavity. An outer surface of the first spindle is provided with a first spiral oil groove connecting the first through-hole and the second through-hole. An outer surface of the main screw oil pump is provided with a second spiral oil groove along its length direction, and a spiral direction of the second spiral oil groove is opposite that of the first spiral oil groove.

摘要： An electric pump includes a motor unit rotationally driving a drive shaft, and a pump unit. The pump unit includes a pump rotor that sends the fluid by a driving force of the driving shaft, and a pump housing that covers at least one side of the pump rotor. The pump housing includes an attachment surface extending in the axial direction and in contact with an attached body, first and second flow paths respectively on the suction side and the discharge side, and a partition wall positioned between pump-side openings of the first flow path and the second flow path facing the pump rotor, and extends in a direction along the attachment surface, and locations of attachment-side openings of the first flow path and the second flow path on the attachment surface are displaced from each other on the attachment surface in the axial direction.

摘要： A hermetic compressor is provided that may include a vane that is inserted into a roller, rotates with the roller, and is pushed out toward an inner circumference of a cylinder by rotation of the roller to divide the compression chamber into a plurality of spaces. The vane may include a body having a sealing surface that contacts the inner circumference of the cylinder and inserted into the roller; and a guide that extends from an axial end of the body in a direction crossing a direction the vane slides out, and that is slidably inserted into a guide groove formed on at least one of the first bearing or the second bearing to restrain the vane from sliding out of the roller toward the inner circumference of the cylinder.
