摘要： A scroll compressor includes a compression mechanism including fixed and movable scrolls. The fixed and movable scrolls have end plates and spiral laps. The laps are engaged to form a compression chamber. The end plates are in pressure contact around the compression chamber to form a thrust sliding surface. The thrust sliding surface has an oil groove extending around the compression chamber. High-pressure refrigerating machine oil is supplied to the oil groove. During orbiting of the orbiting scroll, at least in a region serving as a suction space of fluid in an outer peripheral portion of the compression chamber, an outer seal length from an outer peripheral edge of the oil groove in the thrust sliding surface to an outer edge of the movable end plate is smaller than an inner seal length from an inner peripheral edge of the oil groove to a peripheral edge of the compression chamber.

摘要： A scroll compressor includes a pressing mechanism, a pushback mechanism and an adjustment mechanism. The pressing mechanism applies a pressing force toward a fixed scroll to the back side of an end plate portion of an orbiting scroll. The pushback mechanism applies a pushback force separating the orbiting scroll from a fixed scroll to the front of the orbiting scroll. The adjusting mechanism has a low-pressure portion filled with a fluid of a lower pressure than the discharge pressure of the compression mechanism, and a communicating groove formed in a sliding surface of an outer peripheral portion of the fixed scroll so as to communicate with the low-pressure portion in a first rotational angle range in order to reduce an upsetting moment of the orbiting scroll, and to be blocked from the low-pressure portion in a second rotational angle range other than the first rotational angle range.

摘要： A scroll compressor includes a compression mechanism having fixed and movable scrolls defining a compression chamber, an introduction mechanism, and an auxiliary introduction mechanism. The introduction mechanism supplies fluid from the compression chamber to a back-pressure chamber supply throughout a first period. The auxiliary introduction mechanism has an auxiliary introduction passage and a check valve. The auxiliary introduction mechanism supplies fluid from the compression chamber to a back-pressure chamber supply throughout a second period. The second period includes a time point prior to the first period.

摘要： A compressor includes a casing having a cylindrical barrel, a compression mechanism, and an electric motor. The electric motor has a tubular stator, and a rotor disposed inside the stator. The stator has a back yoke forming an outer peripheral portion of the stator, a plurality of teeth extending radially inward, and slots. A fluid passage extends between an outer peripheral surface of the stator and an inner peripheral surface of the barrel. The fluid passage has a plurality of wide portions arranged in a circumferential direction of the stator, and a narrow portion provided between adjacent ones of the wide portions. The narrow portion has a smaller radial width than each of the wide portions. Each wide portion is provided in the outer peripheral surface of the stator and between a core cut having a recessed groove shape between the slots and the inner peripheral surface of the barrel.
