摘要： A compressor includes a cylinder (101); a cylinder chamber (103); a piston turning along an inner peripheral surface (101a) of the cylinder (101); a blade that partitions the cylinder chamber (103) into a high pressure side region and a low pressure side region together with the piston; a blade hole (104) allowing the blade to advance and retract; a suction passage (120) that extends from an outer peripheral surface of the cylinder (101) to the inner peripheral surface (101a) of the cylinder (101) and guides a refrigerant to the cylinder chamber (103); and a pipe connection member (200) having a press-fitting portion (201b) press-fitted into the suction passage (120) from a radially outer side of the cylinder (101). A distance (R2) from a center point (O1) of the cylinder chamber (103) to the press-fitting portion (201b) is equal to or longer than a distance (R1) to a radially outer end of the blade hole (104).

摘要： In two compression units (41, 51) of a compressor, phases of respective pistons (45, 55) are configured to be opposite to each other. The piston (45, 55) has a non-circular outer peripheral surface, whereas a cylinder chamber (60, 70) has an inner peripheral surface of which shape is determined based on an envelope of the outer peripheral surface of the piston (45, 55) in rotation. The compressor includes an introduction section (67, 68, 163a, 164a) configured to introduce an intermediate-pressure refrigerant into a compression chamber (75) of the compression unit (41, 51).

摘要： A rotary compressor includes a cylinder, a piston, and a pair of bushes (45a and 45b) which sandwich a blade (35) integrally formed with the cylinder to support the blade (35). At least one of the pair of bushes (45a and 45b) includes an oil supply passage (1) formed from a flat side surface (7) to a curved side surface (6) of the bush (45a, 45b), a blade-side oil reservoir (2) formed on the flat side surface (7) such that one end of the oil supply passage (1) is open to the blade-side oil reservoir (2), and a groove-side oil reservoir (3) formed on the curved side surface (6) of the bush (45a, 45b) such that the other end of the oil supply passage (1) is open to the groove-side oil reservoir (3). The groove-side oil reservoir (3) is wider than the blade-side oil reservoir (2).

摘要： A fastening bolt (70) fastens a first cylinder head member (61), a first cylinder (51), and a second cylinder head member (62) together. The first cylinder head member (61) is disposed adjacent to one axial end of the first cylinder (51). The end face of the first cylinder head member (61) in contact with the first cylinder (51) is provided with a protecting groove (80). The protecting groove (80) is formed to be closer to the center of the first cylinder (51) than the fastening bolt (70) is, and has a groove width (W) shorter than a groove depth (D) thereof.

摘要： Provided is a compressor whose compression efficiency is high. A valve assembly (280) is provided between a compression chamber (S1, S2) and an injection pipe (90). Here, the valve assembly (280) has an opening forming member (281), a valve body (282), and a spring member (283). The opening forming member (281) forms an opening (281a). The valve body (282) moves in accordance with differences between the pressure of refrigerant supplied from the injection pipe (90) and the pressure of refrigerant in the middle of compression in the compression chamber (S1, S2) and blocks the opening (281a) when the valve body has moved from the compression chamber (S1, S2) side to the injection pipe (90) side. The spring member (283) is disposed on the injection pipe (90) side of the opening (281a) and applies force in the direction of the injection pipe (90) to the valve body (282).
