Abstract: A scroll compressor includes a fixed scroll and an orbiting scroll. An orbiting angle of the orbiting scroll when a compression chamber is formed and compression of fluid is initiated is referred to as an orbiting initiation angle. An orbiting angle of the orbiting scroll when the compression of the fluid is terminated is referred to as an orbiting termination angle. An orbiting angle of the orbiting scroll when an end of the orbiting spiral wall initiates contact with an arcuate portion of the fixed spiral wall is referred to as a distal end contact initiation angle. The formation point distance is a peak in at least one of orbiting angles obtained by subtracting integer multiples of 360° from an orbiting angle in a range from the distal end contact initiation angle to the orbiting termination angle.

Abstract: A scroll compressor includes a rotation shaft, a fixed scroll, a movable scroll, a compression chamber, and a shaft support. A movable member is movable in an axial direction of the rotation shaft toward and away from the movable scroll. A rotation restriction mechanism includes a pin and a hole that is loosely fitted into the hole. An orbital radius switching mechanism moves the movable member in a first direction when a rotation speed of the rotation shaft is increased, which decreases an orbital radius of the pin relative to the hole so that an orbital radius of the movable scroll is decreased, and moves the movable member in a second direction when the rotation speed of the rotation shaft is decreased, which increases the orbital radius of the pin relative to the hole so that the orbital radius of the movable scroll is increased.

Abstract: A scroll type compressor includes a housing, a rotary shaft rotatably supported in the housing and having an eccentric pin projecting from an end of the rotary shaft, a fixed scroll member and a movable scroll member facing the fixed scroll and forming a pair of compression chambers therewith. The scroll type compressor further includes a balancer-integrated bush having an eccentric hole to receive the eccentric pin and disposed between the eccentric pin and the movable scroll. The balancer-integrated bush is configured to receive rotational force from the rotary shaft to cause the movable scroll member to make an orbital movement. An elastic member provided between the rotary shaft and the balancer-integrated bush in an elastically deformed state to always apply a preload to the movable scroll member via the balancer-integrated bush in a direction that increases an orbital radius of the movable scroll member.

Abstract: A scroll compressor includes a rotation shaft, a fixed scroll, a movable scroll, a compression chamber, a shaft support, a housing, a movable member arranged in the shaft support, and a rotation restriction mechanism configured to restrict rotation of the movable scroll. The rotation restriction mechanism includes pins, recesses into which the respective pins are loosely fitted, and the movable member. The movable member includes the pins or the recesses. A switching mechanism is configured to switch the movable member between a state in which movement of the movable member in a radial direction of the rotation shaft is restricted and a state in which the restriction is canceled and the movable member can move freely, which changes a movable range of the movable member in the radial direction so that an orbital radius of the movable scroll is changed.
