    摘要: A scroll-type refrigerant compressor having a movable scroll unit and a stationary scroll unit which has a fixed stationary end plate in which a plurality of bypass ports and a discharge port are formed through which the refrigerant compressed in the pockets formed between the movable and stationary scroll units is discharged via check valves covering the bypass ports and the discharge port and preventing a reverse flow of the discharged refrigerant into the pockets. The compressor further having a suction port fluidly connected to an evaporator of an air-conditioning system, a delivery port fluidly connected to a condenser of the air-conditioning system, and a fluid channel for providing a fluid communication between the suction and delivery ports via a solenoid-operated valve for blocking and unblocking the fluid channel. The compressor can be switched from the ordinary 100% capacity to 0% capacity and vice versa.

    摘要: A swash plate type compressor having pistons, each defining on opposite sides compression chambers 38 and 39. The cross sectional area of the operating chamber 39 located adjacent the driving source is larger than the cross sectional area of the operating chamber 38 located away from the driving source in such a manner that the axial force F0 generated in a rotating shaft 5 due to the difference between the pressure at the swash plate chamber and the atmospheric pressure is substantially canceled by the axial forces F1 and F2 generated in the rotating shaft due to the refrigerant pressure acting on the piston 8 in the operating chambers 38 and 39.

    摘要: A swash plate type variable capacity compressor having rotary valves 16 and 17 that rotate together on a rotating shaft 1. The rotary valves 16 and 17 are arranged on the shaft 1 in such a manner that, upon one complete rotation, the rotary valves 16 and 17 are connected, in sequential manner, for respective rotating angles, with circumferentially spaced piston chambers Sp and Sp' via respective intake passageways on the rotary valves 16 and 17. The arrangement of the intake passageway Pr and Pr' is such that the value of the rotating angle in a communication between the intake passageways Pr and Pr' and the piston chamber changes in accordance with the axial position of the rotary valves 16 and 17 on the shaft 1. Control of the rotating angle can vary the effective volume of the piston chambers Sp and Sp', thereby continuously varying the compressor capacity.

    摘要: A spool 9 is connected to the rotating shaft 1 so that the spool 9 is slidable with respect to the shaft 1, while the rotating movement of the shaft 1 is transmitted to the spool 9. The spool 9 is formed with a first recess 9-3 of a reduced circumferential extension for obtaining a reduced compression capacity and a second recess 9-4 of an increased circumferential extension for obtaining a full capacity of the compressor. An intake pressure is always opened to a side of the spool, while an intermediate chamber is formed on the other side of the spool. A spring 10 is arranged for causing the spool 9 to be moved toward the intermediate pressure chamber. At the instant the compressor is brought into operation, introduction of the intake gas occurs via the first recess 9-4, thereby obtaining a compression capacity of 3 to 5% compared to the full capacity of the compressor.

    摘要: In a scroll compressor, the moving scroll member is engaged with the stationary scroll member while centrally offset from each other so that they define an actuation chamber between them. When driven by the crank of the compressor shaft and blocked against rotation by the rotation restricting plate, the moving scroll member revolves to compress the fluid in the actuation chamber, and because of the relationship between the compression reaction force and the driving force, a moment is produced to incline the moving scroll member, so that the moving scroll member rises at a portion of the thrust bearing plate, the contact pressure between the scroll members is increased, and a larger driving force is required. Accordingly, the attraction force of the magnet and magnetic body is utilized to press the moving scroll member against the thrust bearing plate. This force can be generated due to the attracting force or repulsing force between magnets, or by the force of a spring. Therefore, according to the present invention, the tooth width of both scroll members can be made larger.

    摘要: A fluid machine for a gas compression refrigerating system comprises a first and a second working for performing a pump mode operation, in which working fluid of low pressure is sucked into and compressed by the working chambers. The fluid machine further comprises valve mechanism for selectively forming a motor mode passage in combination with a fluid passage change-over device, so that super heated working fluid of high pressure is introduced into at least one of the working chambers to perform a motor mode operation, in which the high pressure working fluid is expanded in the working chamber to obtain mechanical energy. The fluid machine according to the invention, therefore, performs the pump mode operation at one of the working chambers and at the same time the motor mode operation at the other working chamber.

    摘要: In a scroll type compressor, when the operation of the compressor is stopped, compression chambers, for compressing a fluid, and a suction chamber are communicated with each other through bypass holes, and a spool valve to open and close the holes, so that the pressure in the compression chambers are lowered and the occurrence of a shock caused by a sharp increase in the load is prevented at the next start. Since the discharge pressure to drive the spool valve is introduced from a position upstream of the discharge valve, pressure is quickly lowered when the compressor stops, so that the spool valve can be quickly opened. Therefore, even when the compressor is frequently started and stopped, the occurrence of a shock can be positively prevented when the compressor starts.
