<P>PROBLEM TO BE SOLVED: To surely and stably supply a lubricating oil to both a bush and a crank pin of a scroll compressor to improve durability, and also to suppress occurrence of noise and vibration. <P>SOLUTION: A guide groove 16 for guiding the lubricating oil G radially inward is formed on the inner wall surface 12a of a front housing 12 forming the scroll compressor. Meanwhile, an oil passage connecting an oil storage chamber with a supply hole of a fixed scroll is formed on a contact surface of a rear housing. After the lubricating oil G flows from the oil storage chamber to the supply hole through the oil passage, the lubricating oil G supplied to a driving part along the outer peripheral surface of the fixed scroll and attaching to the inner wall surface 12a is collected by a branch groove 20 and a vertical groove 18 and is dripped to the crank pin 76 located downward. <P>COPYRIGHT: (C)2012,JPO&INPIT |
