SWASH-PLATE TYPE COMPRESSOR

摘要

PURPOSE:To improve seizureproofness by reducing the leak of lubricating oil into low-pressure chambers by cutting-off the communication between low-pressure chambers and the holes for through bolts for the tightening of a compressor and permitting the sufficient lubrication of the slidable part of the compressor. CONSTITUTION:A through bolt 10 is arranged in the vicinity of the outermost periphery of a swash-plate chamber 11. In this part, the density of lubricating oil is high because of the centrifugal force due to the revolution of a swash plate 4. The captioned apparatus is constituted so that the lubricating oil in this part does not leak into low-pressure chambers 13 and 13' through the through-bolt holes 21 and 21'. Therefore, partitioning walls 1a and 1a' are formed to cut-off the communication between through-bolt holes 21 and 21' and the low pressure- chambers 13 and 13'.
