In a swash plate type compressor, an oil separating chamber is arranged in the course of the flow of coolant gas from an inlet to a low pressure chamber. An oil accumulating chamber is formed between the rear end of the drive shaft and the rear side cover. The oil accumulating chamber is communicated with the oil separating chamber and with a thrust bearing through an oil passage formed in the drive shaft. The thrust bearing is lubricated by use of oil from the oil accumulating chamber.

A swash plate type compressor comprising a cylindrical compressor housing having an inlet for coolant gas, a cylinder block assembly supported within said compressor housing, a drive shaft rotatably supported by radial bearings at its ends in said cylinder block assembly and having an oil passage therein opening at one end to the rear end thereof and at the other end to thrust bearings, front and rear side covers disposed at opposite ends of said cylinder block assembly, said side covers disposed at opposite ends of said cylinder block assembly, said side covers having a low pressure chamber at a radially central portion and a high pressure chamber spaced radially outwardly from the low pressure chamber, seal means disposed at the front end of said drive shaft, front and rear valve plates interposed between said cylinder block assembly and respective ones of said side covers, and a swash plate fitted between said thrust bearings on said drive shaft so as to rotate with said shaft, said cylinder block assembly forming therein a swash plate chamber enclosing said swash plate; at least one main oil accumulating chamber positioned at the bottom of said cylinder block assembly, a chamber for separating oil from coolant gas and disposed in the course of the flow of the coolant gas from the inlet to the low pressure chamber, and a residual oil accumulating chamber positioned between the rear end of said shaft and said rear valve plate and communicating with the oil separating chamber and the oil passage in said drive shaft to form a means for supplying sufficient oil to said thrust bearings for lubricating same immediately after said compressor is started, wherein the residual oil accumulating chamber comprises a hollow cylindrical member that is closed on an end facing said rear valve plate and is open at an end communicating with said drive shaft passage.
