Patent number: 8469679Abstract: An object of the present invention is to promote oil separation in a sealed container, thereby decreasing the amount of oil discharged to the outside of a compressor. The compressor comprises discharge hole provided at position facing the end surface of a rotor and through which a compressed refrigerant from first and second rotary compression elements is discharged into the sealed container; and a refrigerant flow path which is extended from a space surrounded with a coil end of a stator projecting from the end surface of the rotor to a rotary compression mechanism side to a space of an air gap between the rotor and the stator, to guide the compressed refrigerant discharged through the discharge hole to an electromotive element opposite to the rotary compression mechanism side.Type: GrantFiled: January 15, 2010Date of Patent: June 25, 2013Assignee: SANYO Electric Co., Ltd.Inventors: Hirotsugu Ogasawara, Takahiro Nishikawa, Yoshihisa Kogure, Kazuhiko Arai, Hiroyuki Yoshida

Patent number: 6893237Abstract: There is provided a horizontal rotary compressor capable of improving performance thereof while an oil supply means smoothly supplies oil. A part of a hermetic shell case at the upper side is partitioned by a baffle into an electric element side and an oil pump side, a refrigerant which is drawn from an outside of the hermetic shell case is compressed by a first rotary compression element and a second rotary compression element and discharged toward the electric element side of the baffle, then it is further discharged from oil pump side toward the outside of the hermetic shell case. The baffle closes a flow path area of the refrigerant over an oil level inside the hermetic shell case at a ratio ranging from not less than 50% to not more than 80% during the stoppage of the horizontal rotary compressor.Type: GrantFiled: March 14, 2003Date of Patent: May 17, 2005Assignee: Sanyo Electric Co., Ltd.Inventors: Masaji Yamanaka, Etsuo Toriyama, Manabu Takenaka, Yoshihisa Kogure
