  • Patent number: 9759206
    Abstract: A swash plate type variable displacement compressor includes a collection and supply mechanism. The collection and supply mechanism has collection passages, supply passages, an annular space, an inlet port, and an outlet port. The inlet port is communicable with a working collection passage of the collection passages. The outlet port is communicable with a working supply passage of the supply passages. When the inclination angle of the swash plate is maximum, residual refrigerant gas in a compression chamber of collection phase is collected through the working collection passage and the collected refrigerant gas is supplied to a compression chamber of supply phase. On the other hand, when the inclination angle is less than the maximum, residual refrigerant gas is supplied no more into the supply-phase compression chamber.
