ABSTRACT:
There is provided a swash plate compressor which ensures reduction of pulsation of refrigerant gas during operation thereof and at the same time enhances mechanical efficiency of the compressor. Refrigerant gas delivered from front-side compression chambers is introduced into a front-side discharge chamber, and refrigerant gas delivered from rear-side compression chambers is introduced into a rear-side discharge chamber. At least two refrigerant outlet passages each arranged in a fashion parallel with a plurality of cylinder bores which extend longitudinally through a cylinder block communicate the front-side discharge chamber with the rear-side discharge chamber. A discharge port which is formed in a head secured to a front-side end or rear-side end of the cylinder block permits the refrigerant gas within the front-side and rear-side discharge chambers to be discharged out of the head. One of the at least two refrigerant outlet passages is communicated with the discharge port. The cylinder block is formed therein with a guide passage for communicating an intermediate portion of any of the at least two refrigerant outlet passages other than the one of the at least two refrigerant outlet passages being communicated with the discharge port, with the one of the at least two refrigerant outlet passages being communicated with the discharge port.
