摘要： A tube assembly (60) includes an inner tube (70), an outer tube (80), and a brazing material (61). The inner tube (70) includes an outer peripheral surface first portion (71) and an outer peripheral surface second portion (72). The inner tube (70) constitutes a refrigerant passage of a compressor (11). The outer tube (80) includes an inner peripheral surface first portion (81) and an inner peripheral surface second portion (82). The outer tube (80) constitutes an injection path (54). The inner tube (70) is partially inserted into the outer tube (80) such that the outer peripheral surface first portion (71) is in contact with the inner peripheral surface first portion (81). The brazing material (61) is disposed in a brazing gap (65) between the outer peripheral surface second portion (72) and the inner peripheral surface second portion (82). The brazing material (61) fixes the outer peripheral surface second portion (72) and the inner peripheral surface second portion (82).

摘要： Providing a scroll compressor in which a fixing portion is provided at an end of an arm that supports a bearing, a plurality of welding pins is press-fitted into each of the fixing portion, the welding pins and a casing are welded and fixed, and damage to the arm at the time of press-fitting the welding pins is suppressed. The scroll compressor includes a crankshaft, a lower bearing that supports the crankshaft, the arm that extends toward the casing and supports the lower bearing, the fixing portion (96) connected to the end of the arm and fixed to the casing, a first pin (160), and a second pin (260). The fixing portion is provided with a first hole (98a) and a second hole (98b). When the first hole is viewed along a radial direction of the crankshaft, a center (O1) of the first hole overlaps with a minimum sectional area portion (94a) of the arm, and when the second hole is viewed along the radial direction of the crankshaft, a center (O2) of the second hole is outside the minimum sectional area portion of the arm. The first pin is press-fitted into the first hole, and the second pin is press-fitted into the second hole. A holding force of the first pin by the fixing portion is larger than a holding force of the second pin by the fixing portion.

摘要： A scroll compressor (1) of the present invention includes a pressing mechanism (75) and a back-flow prevention mechanism (35). The pressing mechanism (75) includes a back-pressure chamber (53) facing a back surface of a movable-scroll end plate (71), and a back-pressure supply path (80) for allowing the back-pressure chamber (53) to communicate with a compression chamber (23) which is in a state right before the compression chamber (23) communicates with an outlet port (64) or a state in which the compression chamber (23) communicates with the outlet port (64). The back-flow prevention mechanism (35) allows refrigerant of the back-pressure supply path (80) to flow from the compression chamber (23) to the back-pressure chamber (53), and prevents fluid of the back-pressure supply path (80) from returning from the back-pressure chamber (53) to the compression chamber (23).

摘要： An injection port (27) communicating with a compression chamber (25) in the course of compression is formed in a fixed scroll (30). Refrigeration oil separated from a refrigerant discharged from a scroll compressor (10) flows from the injection port (27) to the compression chamber (25) together with an intermediate pressure gaseous refrigerant. Each of bottom lands (31a, 41a) of the fixed scroll (30) and an orbiting scroll (40) has an intermediate bottom region (36, 46) facing the compression chamber (25) communicating with the injection port (27), and a suction side bottom region (35, 45) closer to an outer end of the lap (32, 42) than the intermediate bottom region (36, 46) is. A clearance between the bottom land (31a, 41a) and the end face (42a, 32a) of the lap (42, 32) is larger at the suction side bottom region (35, 45) than at the intermediate bottom region (36, 46).

摘要： A housing (21) includes a bearing portion (22), a body portion (23) continuous with the bearing portion (22) and extending radially outward, a pressing portion (24) provided radially outside the body portion (23) and pressing a casing (10), and a supporting portion (25) extending toward a fixed scroll (30). An end face of the supporting portion (25) near the fixed scroll (30) is a fastening face (25a) to which the fixed scroll (30) is fastened. A gap (G1) is formed between an inner peripheral surface of the casing (10) and outer peripheral surfaces of the body portion (23) and the supporting portion (25). An axial length (L1) of the gap (G1) is greater than or equal to an axial length (L2) of an inner peripheral surface of the supporting portion (25).

摘要： A scroll type compressor (10) includes a compression-chamber-forming member (35, 40), a housing (50), an injection passage (44), and an auxiliary introduction mechanism (80). The compression-chamber-forming member forms a compression chamber (31). The housing (50) forms an intermediate-pressure-side back pressure chamber (56) in which refrigerant for applying back pressure to the compression-chamber-forming member is accumulated. The injection passage (44) is formed in the compression-chamber-forming member (35, 40) and/or other surrounding members (50,90), and is linked to the compression chamber (31). The auxiliary introduction mechanism (80) is provided to the compression-chamber-forming member, the compression chamber (31) and the intermediate-pressure-side back pressure chamber (56) communicating via the auxiliary introduction mechanism (80) when injection pressure, which is the pressure of the refrigerant flowing from the injection passage (44) into the compression chamber (31), is higher than the pressure in the back pressure chamber.
