    摘要: A screw compressor includes an economizer passage (50) provided in a casing (1) and allowing an outside of the casing (1) and a slide groove (14) in which a slide valve (12) is provided to communicate with each other, and an economizer port (12p) provided in the slide valve (12) and allowing the economizer passage (50) to communicate with one of compression chambers (11) in accordance with a position of the slide valve (12). The slide valve (12) gradually advances a timing of starting discharge by moving from a discharge side toward a suction side. The economizer port (12p) is provided at a position where the economizer port (12p) communicates with a suction-pressure chamber (1C) when the slide valve (12) is positioned at an extreme end on the suction side.

    摘要: It is aimed to enhance compressor efficiency by both reducing an amplitude of pressure pulsations and reducing pressure losses in a discharge muffler space into which is discharged a refrigerant compressed at a compression unit. A low-stage discharge muffler space (31) is formed in the shape of a ring around a drive shaft (6). In the low-stage discharge muffler space (31), a discharge port rear guide is provided in the proximity of a discharge port (16) through which is discharged the refrigerant compressed by a low-stage compression unit (10). The discharge port rear guide is provided at a flow path in one direction out of two flow paths from the discharge port (16) to a communication port (34) in different directions around the drive shaft (6), and prevents the refrigerant from flowing in that direction, thereby causing the refrigerant to circulate in a forward direction in the ring-shaped discharge muffler space.

    摘要: The provision of a refrigerating air conditioner that has no limitation on the structure of the main compressor mechanism, and that the lubricating oil levels within the first hermetic vessel and the second hermetic vessel can be regulated without the need for adjusting the installation levels of the first hermetic vessel containing the main compression mechanism and the second hermetic vessel containing the sub-compression mechanism.
    The refrigeration air conditioner includes a first equalizer pipe (21) connecting a bottom portion of a first hermetic vessel (8), which contains a main compression mechanism (7) and lubricating oil (9), to a bottom portion of a second hermetic vessel (4), which contains an expansion mechanism (2), a sub-compression mechanism (3) and the lubricating oil (9). Also included is a second equalizer pipe (22) connecting a side of the second hermetic vessel (4) at a position higher than the requisite minimum oil level (A) to a suction side of the main compression mechanism (7). The space within the second hermetic vessel (4) is isolated from the expansion mechanism (2) and the sub-compression mechanism (3), and the pressure within the second hermetic vessel (4) is not dependent upon the pressure within the expansion mechanism (2) and the pressure within the sub-compression mechanism (3).

    摘要: An object of the present invention is to provide a refrigerant compressor in which amount of discharge that is removed to a refrigerant circuit of lubricating oil that is supplied to a compressing mechanism is reduced. The refrigerant compressor includes: an electric motor that is constituted by a stator and a rotor that are disposed inside a sealed vessel; a compressing mechanism that is driven by a crank shaft that is fitted into the rotor; a lower portion oil pool that stores in the sealed vessel a lubricating oil that lubricates the compressing mechanism; and an upper counterweight that is disposed on an upper end of the rotor, refrigerant gas that is compressed by the compressing mechanism being discharged inside the sealed vessel, and the discharged refrigerant gas passing through a gas channel that is formed on the electric motor, being moved from a lower space to an upper space with respect to the electric motor, and then being discharged outside the sealed vessel. An oil return flow channel is formed on the upper end of the rotor toward a lower end from a vicinity of a leading end portion of the upper counterweight in a direction of rotation, and oil that is expressed in a vicinity of the rotor is directed to the oil return flow channel.

    摘要: The present invention provides a highly efficient and highly reliable scroll fluid machine that suppresses fluctuations in port aperture area during each revolution of an orbiting scroll while ensuring port aperture area. In the present scroll fluid machine, suction ports for sucking in a working fluid are disposed on a second base plate so as to have openings in a vicinity of a winding start end portion of a second spiral tooth, and near an inward facing surface of the second spiral tooth at a position that is separated by an involute angle of approximately 90° from the winding start end portion of the second spiral tooth. Discharge ports for discharging the working fluid are disposed on a first base plate so as to have openings in a vicinity of a winding start end portion of a first spiral tooth, and near an inward facing surface of the first spiral tooth at a position that is separated by an involute angle of approximately 90° from the winding start end portion of the first spiral tooth.
