摘要： In a piston type compressor according to the present invention, a center muffler chamber 39 is defined in a retaining portion 37 inside a discharge chamber on the rear side. The discharge chamber 27 on the rear side is communicated with the center muffler chamber 39 through a communication hole 40 bored in the retaining portion 37. In the discharge chamber 27 on the rear side, therefore, a flow passage of a discharge refrigerant gas flowing through the communication hole 40 and the center muffler chamber 39 is so defined as to extend from each port 32b to an external refrigerating circuit.

摘要： A double-headed piston compressor includes a pair of opposite discharge chambers. Each discharge chamber is defined by a large annular wall and a small annular wall. The annular walls are located about the axis of the drive shaft. A limit wall is formed in each housing and is located in each discharge chamber. Each limit wall extends substantially radially to connect the annular walls near the outlet of the discharge chamber. Therefore, each discharge chamber forms a gas passage, which extends circularly about the axis of the drive shaft from the limit wall to the outlet. Compressed gas discharged from the cylinder bores to each discharge chamber through the discharge ports flows in one direction toward the outlet. As a result, pulsation of compressed gas is attenuated.

摘要： A compressor has an odd number of aligned pairs of cylinder bores. A double-headed piston is accommodated in each aligned pair of bores. The time at which gas is discharged from each cylinder bore is different from that of all of the other cylinder bores. The compressor has a pair of reducing devices, one reducing the pulsation amplitude of the gas discharged from the front cylinder bores and the other reducing the pulsation amplitude of the gas discharged from the rear cylinder bores. The reducing devices reduce the gas pulsation amplitudes of the front and rear cylinder bores at a substantially equal rate. Each reducing device includes a discharge chamber for receiving the gas discharged from the associated cylinder bores and a discharge passage connected to the discharge chamber. The discharge chambers of the reducing devices have equal volumes, and the discharge passages of the reducing devices have equal lengths and equal cross-sectional areas. This structure improves the vibration characteristics of the compressor and thus reduces noise.

摘要： A compressor having a housing formed by joining a plurality of housing components. A plurality of muffler elements are formed integrally with the housing components along the periphery of the housing. A muffler chamber is defined in the housing by coupling the housing components to one another. A large volume chamber and a small volume chamber are defined in the muffler chamber and connected to each other. An inlet is provided in at least one of the muffler elements for drawing the gas in the discharge chamber into the large volume chamber. An outlet is provided in the muffler elements for discharging the gas in the small volume chamber into the external circuit. The arrangement and construction of the housing is such that the pressure pulses in the discharge gas are reduced, and thus vibration and noise are reduced.

摘要： A climate controller for an automobile, comprising a compressor and a receiver arranged in an engine compartment of the automobile, a condenser located at an outside-air inlet of the engine compartment, an expansion member and an evaporator disposed in a passenger compartment of the automobile, and a closed-loop refrigerant passage connecting the compressor, the condenser, the receiver, the expansion member and the evaporator in sequence for circulating a refrigerant through these components to establish a refrigerating cycle. The climate controller further includes a valve arranged in a part of the closed-loop refrigerant passage extending from the evaporator through the compressor to the condenser. The valve is actuated to intersect a communication of the refrigerant through the part of the passage when an operation affecting temperature of both the compressor and the condenser becomes ineffective, and to allow the communication when the operation becomes effective.
