<p>PURPOSE:To cool and lubricate a driving part well by a method wherein gas refrigerant, separated in an accumulator, is sucked into the driving part under a condition that it is mixed with predetermined amounts of liquid refrigerant and lubricating oil and, subsequently, the gas refrigerant is sucked into a suction chamber. CONSTITUTION:The sucked refrigerant is introduced into a separator 18 from a refrigerant pipeline 29 through a pipe 21 and, then, gas and liquid are separated. The liquid refrigerant and the lubricating oil drip to the lower part of the accumulator 17 through holes 22 of a holding plate 19 and are reserved therein. The gas refrigerant, which flows into the lower part through first suction path 24, flows into a driving chamber 56 through a supplying hole 27 under a condition that it is mixed with the liquid refrigerant and the lubricating oil. The refrigerant, which flows into the driving chamber 56, cools and lubricates a swash plate 7, a shoe 12, a piston 11 or the like and is sucked into the suction chamber 33 through the second suction path 41 under a condition that the liquid refrigerant is vaprized and changed into the gas refrigerant perfectly.</p> |
