<p>PROBLEM TO BE SOLVED: To prevent the liquid refrigerant to be returned from an outside refrigerant circuit through a suction passage into a compression machine by moving an blocking body to a closed position of the suction passage certainly at the time of the minimum discharge displacement operation of the compressor. SOLUTION: A rough surface is formed at least one side of the junction surfaces between valve bodies 59, 61 arranged corresponding to valve holes 58, 60 so as to be positioned in the periphery of the valve holes 58, 60 formed in a valve plate 14 and the valve plate 14. The valve bodies 59, 61 are not stuck to the valve plate 14 according to the formation of the rough surface. Thereby, a lubricating oil and refrigerant gas are discharged from the inside of a cylinder bore 23 at the time of the minimum discharge capacity operation of a compression machine, and a spool 47 as a blocking body is certainly moved and arranged to a closed position of a suction passage 35.</p> |
