<p><P>PROBLEM TO BE SOLVED: To improve reliability of a lubricated part by effectively using majority of oil existing in a swash plate chamber of a compressor. <P>SOLUTION: Oil adhering on fixing bolts 5a, 5b at a position near a side wall 13 of a front housing 1 drips into each large diameter hole 32 and flows out to oil-collecting grooves 35, 36 by its own weight. Part of oil flowing on an inner wall surface 34 of a side wall 13 flows into the oil-collecting grooves 35, 36 and sub collecting grooves 39, 40. Oil in the sub collecting grooves 39, 40 flows into the oil-collecting grooves 35, 36 via each large diameter hole 32 of the fixing bolts 5a, 5b. Oil in the oil-collecting grooves 35, 36 flows in a circumference direction of the side wall 13 and is introduced into oil introduction grooves 37, 38. Oil in the oil introduction grooves 37, 38 flows in a drive shaft 6 direction, is supplied to a space 10 via oil introduction holes 41, 42 connected at lower ends, and lubricates a shaft seal device 11 and a radial bearing 9 which are lubricated parts. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
