Abstract
A suction chamber and a discharge chamber are defined in a front housing member. A crank chamber is defined between a cylinder block and a rear housing member. A drive shaft passes through the suction chamber and extends from a front end of a housing. The drive shaft is supported by the housing. A shaft sealing assembly for sealing the drive shaft is located in the suction chamber. In the cylinder block and a valve plate, a bleed passage is formed for connecting the crank chamber with the suction chamber. The bleed passage is inclined downward toward the suction chamber. The outlet of the bleed passage is above the shaft sealing assembly. In the suction chamber, a reservoir, which stores lubricating oil supplied through the bleed passage, is surrounds a lower part of the shaft sealing assembly.
