| description | In a swash plate type variable capacity compressor that changes a stroke of a piston by controlling the pressure of a crank chamber (6), lubrication oil contained in refrigerant gas is maximally prevented from being circulated outside the compressor. Some of discharged refrigerant gas in a discharge chamber (22) flows into the crank chamber (6) through a communication passage (25) (25a and 25b) and a control valve (27), while some of the discharged refrigerant gas flows out to a suction chamber (21) from the crank chamber (6) through a second communication passage (26) and an orifice (28), and the pressure of the crank chamber (6) is controlled through a balance between an inflow amount and an outflow amount. Oil storage chamber (30) extends downstream of the control valve (27) on the first communication passage (25) to separate oil and store the separated oil. Oil return passage (31) returns the oil stored in the oil storage chamber (30) to the crank chamber (6). |
