Abstract: A scroll compressor is provided. An orbiting angle of the orbiting scroll when the 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 completed 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 the arcuate portion of the fixed spiral wall before compression is completed is referred to as a distal end contact initiation angle. The formation point distance reaches a minimum value at least at one of a first orbiting angle or a second orbiting angle.

Abstract: The foil bearing includes a housing, a top foil, and bump foils. The bump foil includes first support portions that contact an outer circumferential surface of the top foil, second support portions that contact an inner circumferential surface of the housing, and coupling portions that couple the first support portions and the second support portions together such that the first support portions and the second support portions are disposed alternately in a rotation direction of a rotating body. When a load input from the rotating body increases, the bump foil is deformed to increase one of the number of the first support portions that contact the outer circumferential surface of the top foil and the number of the second support portions that contact the inner circumferential surface of the housing before increasing the other one of the numbers.

Abstract: A compressor includes a discharge chamber, compressor chamber, valve plate, and discharge reed valve. The valve plate includes a fixing surface, exposed to the discharge chamber, and a discharge port, which communicates the discharge chamber and the compression chamber. The discharge reed valve includes a fixed portion, fixed to the fixing surface, a base portion, separable from the valve plate, and a valve portion, which closes the discharge port. The valve plate includes an annular seal surface, recessed groove, receiving surface, and support surface. The seal surface contacts the valve portion around the discharge port. The recessed groove is arranged in the fixing surface outward from the seal surface. The receiving surface is flush with the fixing surface and contacts a distal region of the valve portion. The support surface is flush with the fixing surface and contacts a central region of the valve portion.

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: The present invention provides a variable displacement swash plate type compressor that reduces wear of cylinder bores and the amount of blow-by gas. Each piston of the compressor has a piston main body, which has a distal portion located at an end corresponding to the compression chamber. A tapering portion and an arcuate portion are formed in the distal portion. The arcuate portion is continuous with an end of the tapering portion that is closer to the compression chamber. The tapering portion and the arcuate portion each have a diameter that increases toward the skirt. The tapering portion has a tapering angle that is in a range from 0.45 degrees to 1.5 degrees. The distance between the distal end of the piston main body and a starting point of the tapering portion on an end closer to the skirt is set in a range from 1.5 mm to 5.0 mm.

Abstract: A compressor valve structure permits improvement in durability and volumetric efficiency of a compressor and limits power losses. The width of the base portion of each suction reed valve is shorter than the width of the valve flap. The valve base plate has support portions, receiving portions, main coupling portions, and auxiliary coupling portions. Each support portion receives a central area of corresponding one of the valve flaps. The receiving portion receives a distal area of the valve flap. The main coupling portion extends from the support portion and couples the support portion to the receiving portion. The auxiliary coupling portion extends from the support portion. The suction ports are formed through the valve base plate, while leaving the support portions, the receiving portions, the main coupling portions, and the auxiliary coupling portions.

Abstract: A compressor includes a valve base plate, which is arranged between a suction chamber and a compression chamber and has a suction port. The valve base plate includes a sealing surface, a recessed groove, a receiving surface, and a support surface. The sealing surface is flush with a fixing surface and contacts the valve portion in an annular manner. The recessed groove is located at an outer side of the sealing surface and recessed with respect to the fixing surface. The recessed groove includes a bottom portion and separates an edge portion of the valve portion from the bottom portion. The receiving surface is flush with the fixing surface and capable of contacting a distal zone of the valve portion. The support surface is flush with the fixing surface and capable of contacting a middle zone located at an inner side of the sealing surface of the valve portion.
