REFRIGERANT COMPRESSOR WITH IMPROVED LUBRICATION A slant plate type compressor such as a wobble plate type refrigerant compressor is disclosed. The compressor includes a compressor housing having a cylinder block provided with a plurality of cylinders, and a crank chamber adjacent the cylinder block. A front end plate is attached on one end surface of the compressor housing. A cylinder head is formed on the other end surface of the compressor housing having a suction chamber and a discharge chamber. The suction chamber surrounds the discharge chamber. A refrigerant inlet port is formed on the compressor housing and introduces refrigerant directly into the crank chamber. A plurality of communication holes are formed through the cylinder block to communicate between the crank chamber and the suction chamber. Therefore, lubricating oil mixed with refrigerant is sucked into the crank chamber and lubricates the moving parts of the compressor. The accumulated oil then flows along with refrigerant from the crank chamber to the suction chamber through the communication holes. As a result, the maximum compression capacity is maintained, while adequate lubrication is performed without a sump portion. |
