    摘要： A scroll compressor includes a compressor housing containing an orbiting scroll member, a non-orbiting scroll member, bands disposed between the non-orbiting scroll member and the compressor housing, a suction chamber, a discharge chamber, and one or more intermediate injection chamber defined by the bands. The non-orbiting scroll member includes one or more intermediate injection ports fluidly connecting the one or more intermediate injection chambers to at least one compression pocket formed by the intermeshed scroll members. A heating, ventilation, air conditioning, and refrigeration system includes a refrigerant circuit with a condenser, an expander, an evaporator, and the scroll compressor fluidly connected. A method of making a scroll compressor includes placing an upper portion of a compressor housing over a non-orbiting scroll member with bands disposed therebetween, and interference fitting the upper portion onto the non-orbiting scroll member via the bands.

    摘要： A scroll compressor, includes: a scroll compression mechanism including an orbiting scroll, a fixed scroll, and a thrust plate supporting a load of the orbiting scroll in a thrust direction; a back-pressure application mechanism that applies, as back pressure, the refrigerant gas compressed by the scroll compression mechanism to a rear surface of the thrust plate; and a floating amount restriction mechanism that restricts an amount of floating of the thrust plate caused by the back pressure. The floating amount restriction mechanism includes a restriction pin that includes a shaft part and a head part, and locks the thrust plate to the head part to restrict the amount of floating. The shaft part passes through the thrust plate and has a front end part fixed to a front housing, and the head part has a diameter larger than a diameter of the shaft part.

    摘要： A vacuum type of scroll pump includes a frame, a stationary plate scroll, an orbiting plate scroll, a non-energized type of tip seal or seals, an eccentric drive mechanism assembled to and supported by the frame and to which the orbiting plate scroll is assembled so as to be drivable by the eccentric drive mechanism in an orbit about a longitudinal axis of the pump, and a mechanism for adjusting the seal(s) created by the tip seal(s) without having to disassemble any of the frame, plate scrolls or parts of the eccentric drive mechanism from one another, i.e., while a pump head assembly of the pump remains intact.

    摘要： There is provided a screw rotor that can ensure safe rotation and can greatly increase a pumping performance of a pump. The screw rotor is placed with a gap between a top end surface of a tooth of a screw portion and an inner wall surface of a stator. A PFA film is provided on the top end surface. If the PFA film of the present invention is provided in a predetermined manner, the width of a gap between a free surface of the PFA film and the inner wall surface of the stator can be made significantly smaller than that of a conventional one, so that the pumping performance is greatly improved. After coating at least the top end surface of the screw rotor with PFA, followed by melting and remelting processes, the PFA film is formed to have a high smoothness on its free surface.
