The ring member having an outer surface comprising a main sealing portion having an axially uniform shape and an outwardly circumferentially projecting flexible lip portion. Also, the inner surface of the ring member comprises an inner bearing portion able to come into contact with a first portion of a bottom surface of the ring groove such that the flexible lip portion of the outer surface is brought into contact with a cylinder wall of the cylinder bore and preflexed inwardly. An inner pressure receiving portion is formed adjacent to the inner bearing portion to receive pressure from the compression chamber, to further flex the flexible lip portion upon a compression stroke of the compressor and thereby allow the ring member to expand and the main sealing portion to come into contact with the cylinder wall of the cylinder bore.

    摘要: The cylinder block assembly (1a) of a swash plate type refrigerant compressor is formed with a suction passageway (17) in which a refrigerant gas containing a mist-like lubricant oil therein is sucked and passed therethrough, and a cylindrical separating chamber (22) is formed by an extension (21) from an inner wall of the suction passageway and has an opening directed toward an entering direction of a flow of the lubricant oil-containing refrigerant gas. The separating chamber (22) is provided with an bottom wall (22a) having a through-hole for an entrance of the oil, communicating between the separating chamber (22) and a swash plate chamber (4). The refrigerant gas containing the lubricant oil therein enters the cylindrical separating chamber (22) arranged in the suction passageway (17) and impringes upon an inner wall (22b) and the bottom wall (22a), whereby the flow direction thereof is changed, and flows out of the chamber through the opening into the suction passageway to thereby separate the lubricant oil from the refrigerant gas. The separated lubricant oil is supplied from the separating chamber (22) into the swash plate chamber (4), without overflowing from the chamber toward the suction passageway.

    摘要: A continuous seal ring member fitted in a ring groove of a piston of a compressor. The seal ring member has a washer-like initial shape with an internal diameter smaller than an outer diameter of the piston, whereby the inner peripheral portion of the seal ring member is expanded when the seal ring member is fitted in the ring groove. The outer peripheral portion of the ring seal member is then axially and inwardly collapsed relative to the inner peripheral portion thereof so that one of the side surfaces of the initial seal ring member constitutes an outer sealing surface for engagement with the cylinder bore and the outer peripheral portion in the original shape is arranged on the side of said compression chamber. A backup ring member fitted in the ring groove on the side of the continuous seal ring member remote from the compression chamber has a surface area abutting against the side surface of the ring groove on the side remote from the compression chamber and sufficient to retain the continuous seal ring member in the ring groove.

    摘要: A valve assembly in a piston type refrigerant compressor is disclosed. The valve assembly includes a retainer formed integrally with a gasket plate for restricting the opening of a discharge reed valve of the compressor, and having on opposite sides at the distal portion thereof stay portions integral with the gasket plate for rigidly holding the retainer. According to the present invention, provision is made to guide some part of the refrigerant gas compressed in a cylinder bore to be discharged into a discharge chamber in such a way that the influence of the discharge gas pressure on the retainer at its distal end is reduced. In some embodiments of the invention, this is accomplished by guiding and allowing part of the gas to flow toward the proximal portion of the retainer to discharge the gas.

The cylinder blocks are connected to a front and rear housing sections in order to cover the cylinders. Each housing section contains a discharge chamber. A drive shaft is rotatable supported by the cylinder blocks. One end of the drive shaft is sealed within the front housing. A swash plate is mounted on the drive shaft and is rotatably disposed within the crank case. A plurality of two-head pistons engage the swash plate via a pair of shoes. The pistons move within their respective cylinders in cooperation with the swash plate. The refrigerant is sucked into each cylinder via a suction passage, and is then compressed therein. The refrigerant is discharged into the external refrigerating circuit through the front and rear discharge chambers, .and the front and rear discharge ports. A discharge passage is provided within the drive shaft, and interconnects the front and rear discharge chambers. A valve is provided at one end of the discharge passage to control the opening of the discharge port in relation to the pressure difference between the front and rear discharge chambers.

    摘要: A swash plate type compressor comprising a swash plate accommodated in a swash plate chamber. Front and rear housings are attached to the cylinder block to form suction chambers and discharge chambers, respectively. A refrigerating medium is introduced from a suction inlet to the suction chambers via the swash plate chamber and discharged from the discharge chambers. A drive shaft is fixed to the swash plate for reciprocally moving pistons. The drive shaft has a discharge passage in the form of an axial bore formed in the drive shaft for connecting the front discharge chamber to the rear discharge chamber. The discharge passage is thus isolated from the suction system.

    摘要: A swash plate type compressor is disclosed which is intended to prevent a hemispherical shoe, provided between the piston and the swash plate, from being spun on slat surface of the swash plate during operation of the compressor. In the preferred embodiment of the invention, the swash plate is formed with a step and the shoe with a cut portion engageable with the step so that the shoe is prevented from being spun on the slant surface of the swash plate which provides a turning moment to the shoe. The step is formed by an annular projection having an annular wall portion defining the inner limit of the slant surface area of the swash plate with which the flat face of the hemispherical shoe is kept in sliding contact, and the cut portion of the shoe has a curved surface conforming to the curvature of the annular wall portion. The shoe is located with its cut portion slidably contactable with the annular wall portion.

    摘要: A swash plate type compressor having axially spaced inlet chambers and outlet chambers located on the side of angularly spaced pistons having each side thereof pump chambers which are connected to inlet chamber when the medium is introduced into the pump chambers, and are connected to the outlet chamber when the medium is removed to the outlet chambers. A swash plate chamber is arranged inside the cylinder block and cooperates with the pistons via respective shoes for reciprocating the pistons in the respective cylinder bores. An inlet of the fluid to be compressed is opened to the swash plate chamber at a circumferential position along the inner wall of the swash plate chamber. Communication passageways for connection of the swash plate chamber with the inlet chambers are arranged on position spaced farthest from the inlet port. The flow of the lubrication oil contained in the gas to be compressed is generated inside the swash plate chamber and comes into contact with all of the shoes, to lubricate same, before being introduced into the communication passageway from the swash plate chamber.
