Abstract
A multi-piston swash plate type compressor with an internal lubricating arrangement for an air conditioning system used in a vehicle such as an automobile comprises a cylinder block body having a swash plate chamber formed therein for receiving a swash plate, and cylinder bores formed therein for receiving pistons. The compressor has a suction chamber which is fed with a refrigerant including a lubrication oil from an evaporator of the air conditioning system, and a discharge chamber which feeds the compressed refrigerant to a condenser of the air conditioning system. The suction and discharge chambers are communicated with each of the cylinder bores through valves. Passages are formed in the cylinder block body for feeding the refrigerant from the swash plate member to the suction chamber in such a manner that the refrigerant flow is guided to positively lubricate movable parts included in the cylinder block body as a component element of the compressor.
