摘要： A compressor may include a shell assembly, a compression mechanism, a driveshaft, a first bearing, a second bearing, a third bearing, and a surface supporting the third bearing. The compression mechanism may include first and second compression members. The driveshaft may be coupled to the first compression member to rotate the first compression member relative to the second compression member. The first bearing may support the driveshaft for rotation about a first axis. The second bearing may support the driveshaft for rotation about the first axis. The third bearing defines a second axis. The third bearing may support the second compression member for rotation relative to the first compression member. The surface may support the third bearing such that the third bearing is able to roll along the surface to move the second compression member and the second axis in a radial direction relative to the first compression member.

摘要： Provided is a scroll fluid machine which can appropriately set a tip clearance between a tooth base and a tooth crest having an inclined portion and can achieve desired performance. An inclined portion in which a distance between opposing surfaces of an end plate of a fixed scroll and an end plate of an orbiting scroll facing each other gradually decreases from an outer peripheral side toward an inner peripheral side is provided. A tip clearance between a tooth crest of a wall of the orbiting scroll and a tooth base of the end plate of the fixed scroll facing the tooth crest at normal temperature is greater on the inner peripheral side than on the outer peripheral side.

摘要： An apparatus for compressing gas-phase fluid including a housing having a wall, a stator having a base plate and a helical wall extending from one side of the base plate, and an orbiter having a base plate and a helical wall extending therefrom. The base plates are disposed such that the wall of the stator and the wall of the orbiter engage with each other to define closed working chambers. The volumes and positions of the working chambers are changed in response to the motion of the orbiter. The apparatus includes a guide device having an opening formed in the base plate of the orbiter and a pin coupled to the housing. The pin engages the opening. A sliding element is disposed between the wall of the housing and the orbiter and coupled to the wall. The pin is pressed into an opening formed in the sliding element.

摘要： A compressor includes a first throttle portion that receives a refrigerant at an intermediate pressure from an injection pipe of a refrigerant circuit, an enlarged flow path portion that receives the refrigerant from the first throttle portion, a second throttle portion that receives the refrigerant from the enlarged flow path portion, and a compression element. The compression element includes a compression chamber that receives the refrigerant from the second throttle portion. The first throttle portion has a flow path cross-sectional area that is narrower than both a flow path cross-sectional area of the injection pipe and a flow path cross-sectional area of the enlarged flow path portion. The second throttle portion has a flow path cross-sectional area that is narrower than the flow path cross-sectional area of the enlarged flow path portion.

摘要： A scroll compressor may include a frame, an orbiting scroll provided with at least one first key groove, a non-orbiting scroll provided with at least one second key groove and coupled to the orbiting scroll to form a compression chamber, and an anti-rotation ring disposed between the frame and the orbiting scroll. The anti-rotation ring may include a ring, at least one first key that axially extends from a first surface of the ring and slidingly coupled to the at least one first key groove of the orbiting scroll, and at least one second key that axially extends from the first surface of the ring and slidingly coupled to the at least one second key groove of the non-orbiting scroll. The first and second keys may be provided along a circumferential direction. This may allow processability of a one-way anti-rotation ring. Further, increase in weight may be prevented while reducing deformation by providing a weight-reduced portion in addition to a reinforcing portion.

摘要： Provided is a compressor which enables reliable separation of oil from a refrigerant gas while suppressing increases in the size of equipment and manufacturing costs. Provided is a compressor (1) including a housing (2), a compression mechanism (13) compressing a refrigerant gas flowing into a suction space (Ss), an oil separation space (So) separating oil from the refrigerant gas compressed by the compression mechanism (13) and guiding the refrigerant gas to a discharge pipe (40), and a separation cylinder (30) disposed along an axis line (X2) of the oil separation space (So) above the oil separation space (So) in a gravitational direction. The separation cylinder (30) has a small-diameter section, a large-diameter section formed below the small-diameter section in the gravitational direction, and an introduction inlet formed in the small-diameter section. The oil separation space (So) has a separation section in which the small-diameter section and the large-diameter section are disposed, the separation section having a first inner diameter larger than a second outer diameter of the large-diameter section, and an oil storage section disposed below the separation section. The refrigerant gas compressed by the compression mechanism (13) flows into the separation section.

The shaft part includes: a cylindrical body part; and a cylindrical coupling part which extends outward from an axial end portion of the body part, and to which the balance weight part is joined. The bush satisfies the following requirements: 1.2≤D2/D1≤1.6; and (a) 1.0≤[(D2−D3)/(D4−D2)]×E1/E2≤3.5, (b) where D1 is the outer diameter of the body part, D2 is the outer diameter of the coupling part, D3 is the inner diameter of the body part, D4 is the outer diameter of the balance weight part, E1 is the Young's modulus of the shaft part, and E2 is the Young's modulus of the balance weight part.
