Patent number: 6942465Abstract: A compressor is disclosed having a gas extraction passage, internally formed in a drive shaft and continuously communicating with a crank chamber and a suction chamber, that has an inlet portion, to be exposed to the crank chamber, is formed in the drive shaft in a radial direction. As a result, mist-like oil accompanied by blow-by gas tending to flow into the gas extraction passage initially impinges upon and adheres to an inner peripheral surface of the inlet portion of the gas extraction passage due to rotational movement of the drive shaft. Namely, oil separation (gas-liquid separation) occurs at the inlet portion of the gas extraction passage. Then, oil separated from the blow-by gas at the inlet portion of the gas extraction passage is forcibly returned to the crank chamber due to a centrifugal force caused by rotational movement of the drive shaft. Accordingly, the compressor has a structure in which oil accompanied by blow-by gas is hard to escape the suction chamber.Type: GrantFiled: March 19, 2003Date of Patent: September 13, 2005Assignee: Calsonic Kansei CorporationInventors: Masaki Kawachi, Masanori Ogawa, Hiroyuki Makishima, Hiroshi Kageyama, Susumu Higano
