摘要： The compressor is provided with an oil separator for separating oil from refrigerant gas introduced into a separation chamber, an annular space for reserving oil separated from the refrigerant gas, and a reservoir chamber for reserving the thus separated oil. The oil separator is provided in a cylindrical hole formed in a discharge chamber from which the refrigerant gas is discharged and a lid for partitioning the cylindrical hole from the discharge chamber is provided in the cylindrical hole. The oil separator introduces the refrigerant gas from the discharge chamber to the separation chamber via the introduction passage. The annular space is provided around the lid and connected to the reservoir chamber via an oil passage. The reservoir chamber is connected to a crank chamber of a pressure lower than that in the discharge chamber.

摘要： A compressor has a discharge passage, an oil separation mechanism, an oil supply passage, and a valve mechanism. The oil supply passage supplies the separated lubrication oil into an oil recovery region. The valve mechanism is formed in the oil supply passage and includes a valve chamber, a spool and an urging member. The spool separates the valve chamber into a first pressure sensing chamber and a second pressure sensing chamber. The amount of the lubrication oil supplied to the oil recovery region is adjusted in such a manner that as the pressure differential between the first and the second pressure sensing chambers increases, the spool slides in the valve chamber and the opening degree of the oil supply passage increases to the maximum and then decreases, and that when the compressor is stopped, the opening degree of the oil supply passage is minimized by the urging force of the urging member.

摘要： A refrigerant gas compressor includes a cylinder block formed with plural cylinder bores, a first housing disposed at the one end of the cylinder block, a second housing disposed at the other end of the cylinder block, a drive shaft supported by the cylinder block and one of the housings, a crank chamber formed in one of the housings, a suction chamber and a discharge chamber formed in one of the housings, a valve plate assembly disposed between the cylinder block and at least one of the housings, a stepped portion formed adjacent to the valve plate assembly to receive a part of the valve plate assembly. A storage chamber is provided for reserving therein oil separated from refrigerant gas. An oil groove is formed by the stepped portion and the valve plate assembly and connecting the storage chamber with one of the crank chamber and the suction chamber.
