Patent number: 6174140Abstract: A compressor having a device for recovering lubricating oil. The compressor includes a discharge chamber and a muffler, which attenuates the pressure pulsation of refrigerant gas sent out from the discharge chamber. The muffler is defined by a muffler base, which is formed on the cylinder block, and a muffler cover, which is attached to the muffler base. The muffler includes a first muffler chamber and a second muffler chamber, which are connected by an opening. The muffler cover has a gas outlet for sending the refrigerant gas out of the compressor from the second muffler chamber. Lubricating oil separated from the refrigerant gas in the first muffler chamber is sent to the crank chamber through a recovery passage. The location of the gas outlet can be easily changed by replacing the muffler cover. Thus, the compressor can be easily adapted to different engine compartments.Type: GrantFiled: December 17, 1998Date of Patent: January 16, 2001Assignee: Kabushiki Kaisha Toyoda Jidoshokki SeisakushoInventors: Masaki Ota, Kenta Nishimura, Hirotaka Kurakake, Hisakazu Kobayashi

Patent number: 6174142Abstract: A pump for moving liquids has an elastomeric housing disposed around the pump. The housing has at least four sides which are primarily planar, whereby the pump can be supported on the bottom of one of the flat sides by orienting the pump so that one of the primarily planar sides is down. This allows the pump to remain in such chosen orientation and the elastomeric housing, which is typically rubber, will substantially prevent vibration of the pump to be transmitted to the surroundings of the pump.Type: GrantFiled: October 5, 1999Date of Patent: January 16, 2001Inventor: Andrew J. Holt
