摘要： A rotary machine, such as a horizontally oriented scroll type refrigerant compressor is disclosed. The compressor includes a compressor housing, an inner block fixedly disposed within the compressor housing, a drive shaft extending substantially in the horizontal direction, and a driven mechanism, such as a compression mechanism operatively connected to one end of the drive shaft. The drive shaft is rotatably supported by the inner block and the compressor housing. A shielding element, such as an annular cylindrical member is fixedly held between the inner block and the compressor housing to prevent the drive shaft from passing through an oil sump of the housing. An internal lubrication oil pump is formed by the elements which are associated with the drive shaft, and is operated by virtue of the rotational motion of the drive shaft in order to supply the lubrication oil from the oil sump to the frictional surfaces of the internal component parts of the compressor. According to the construction and operational manner of the oil pump, the oil pump can be used for various types of horizontally oriented rotary machines. The drive shaft can also rotate without receiving oil viscous drag.

The rotation preventing/thrust bearing device includes a discrete fixed portion, a discrete orbital portion, and bearing elements. The fixed portion includes a first annular race and a first ring, both of which are formed separately. The first annular race is placed in a loose fit surrounding a first annular step in an inner surface of the housing and the first ring is attached to the housing. The orbital portion includes a second annular race and a second ring, both of which are formed separately. The second annular race is placed in a loose fit surrounding a second annular step in an end plate of the orbiting member and the second ring is attached to the end plate of the orbiting member. A plurality of pockets of the rings face one another in generally aligned pairs. A bearing element is received in each aligned pair of pockets to prevent the rotation of the orbiting member by the bearing elements interacting with the first and second rings and to carry the axial thrust load from the orbiting member. The first and second annular anti-wear plates are overlaid surrounding the first and second annular races, respectively. The first and second annular anti-wear plates are fixedly placed within the first and second annular steps respectively in order to prevent the circumferential and radial movement thereof.

摘要： A fixed scroll (16) and a movable scroll (18) cooperatively define compressing chambers therebetween. The movable scroll is driven by a crank pin (12) eccentrically attached to a shaft (11) which is rotated by an external driving source. A surface treatment for abrasion resistance is applied to at least one of an end surface of the crank pin and a confronting end plate of the movable scroll. It may also be arranged that an abrasion-resistant plate is interposed between the end surface of the crank pin and the confronting end plate of the movable scroll.

摘要： A scroll-type refrigerant fluid compressor includes a fixed scroll having a first circular end plate from which a first spiral wrap extends, and an orbiting scroll having a second circular end plate from which a second spiral wrap extends. The spiral wraps interfit each other at an angular and radial offset to form line contacts defining a pair of sealed-off fluid pockets. An anti-wear plate is disposed on one end surface of the second circular end plate of the orbiting scroll that engages with the second spiral element of the orbiting scroll. An annular boss is formed at a central portion of the other end surface of the second circular end plate of the orbiting scroll. An inner end of a drive shaft is operatively connected to the orbiting scroll through a bushing which is rotatably disposed within the boss. An axial hole is centrally formed through the second circular end plate of the orbiting scroll. Mists of the lubricating oil suspended in the refrigerant gas in a central fluid pocket are conducted to an inner space of the boss via an air gap between the second spiral wrap and the anti-wear plate, fine reticular paths at the second circular end plate of the orbiting scroll beneath the anti-wear plate, and the axial hole.

摘要： A scroll-type compressor includes a fixed first scroll member, an orbital second scroll member, and a ball coupling provided as a rotation preventing mechanism for the second scroll member. The ball coupling has a pair of plates integrally formed with ring-like ball rolling grooves and a plurality of balls disposed therebetween. The compressor comprises a driven crank mechanism creating a swing motion for producing an orbital movement of the second scroll member. The amount of variation of the swing angle due to the driven crank mechanism is set within a range predetermined in accordance with a diameter of a ring form of each of the ring-like ball rolling grooves. The variation of the orbital radius of the orbital movement of the second scroll member corresponding to the swing angle may be regulated within a most appropriate range, thereby preventing occurrence of problems in the rotation preventing mechanism with respect to abrasion, performance and durability.

摘要： An electric motor-driven compressor having a connector structure comprising a terminal connecting portion and a casing, the terminal connecting portion being provided with a hole for inserting an external terminal for power supply to an electric motor for driving a compression mechanism incorporated in a compressor housing, the casing covering the terminal connecting portion. In the electric motor-driven compressor, a collar is provided between a core wire and a covering material of a cable, at least a position corresponding to a sealing material provided at the cable inserting portion of the casing. The clearance between the cable and the sealing material can be prevented from increasing even when the cable is increased in temperature during power supply or when the cable is arranged in a bent fashion, and good sealing performance in the casing of the connector can be achieved, thereby enhancing reliability and durability of the electric motor-driven compressor.

摘要： In a rotation preventing mechanism in which a ball (26) is interposed between a pair of races (24, 25) each having a rolling groove surface (24c, 25c) receiving the ball, the rolling groove surface has a bottom portion (24c3, 25c3) of a radius of curvature which is greater than each of those of an outer peripheral portion (24c1, 24c2) and an inner peripheral portion (25c2, 25c2). Each of the radii of the outer peripheral and the inner peripheral portions is approximate to and greater than the radius of the ball. The races are attached to a front housing (10b) and a movable scroll member (20) which carries out orbital motion along a predetermined orbit with respect to the front housing. The rolling groove surface has an annular shape corresponding to the predetermined orbit.

摘要： A scroll-type compressor has a piston valve mechanism for controlling the feeding of lubricating oil to slidable parts of the compressor. The piston valve mechanism includes a cylinder bore that connects a medium pressure chamber and a low pressure chamber, and a piston valve and a spring accommodated with the cylinder bore. The spring resiliently biases the piston valve toward the medium pressure chamber. The piston valve is driven by a pressure difference between the medium pressure chamber and the low pressure chamber, and by the spring. In one embodiment, an inwardly stepped, narrowed portion formed in the cylinder bore engages the piston valve to prevent further compression of the spring.

摘要： A scroll-type compressor includes a fixed first scroll member, an orbital second scroll member, and a ball coupling provided as a rotation preventing mechanism for the second scroll member. The ball coupling has a pair of integrally formed rolling ball regulating plates and a plurality of balls disposed therebetween. The ball coupling is assembled in the compressor at a condition in that an axial preload is provided. The axial preload is set more than an axial force given by the balls to the rolling ball regulating plates during operation of the compressor for correcting deformation of the rolling ball regulating plates. When the compressor is assembled, an axial gap between the first and second scroll members may be properly adjusted. After the assembly and during the operation of the compressor, the behavior of balls may be stable.
