Patent number: 7736138Abstract: A compressor comprises: a cylinder with a compression space; a suction port and a discharge port which communicate with the compression space in the cylinder; a support member which closes an opening of the cylinder; a rotary shaft which is rotatably supported on the support member; a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is rotated and compresses a fluid to discharge the fluid via the discharge port; and a vane which is disposed between a suction port and the discharge port, abuts on one surface of the compression member and partitions the compression space in the cylinder into high and low pressure chambers.Type: GrantFiled: June 13, 2007Date of Patent: June 15, 2010Assignee: Sanyo Electric Co., Ltd.Inventors: Takahiro Nishikawa, Hirotsugu Ogasawara, Takao Kanayama, Yoshiaki Hiruma, Manabu Takenaka, Masazumi Sakaniwa, Akira Hashimoto, Junichi Suzuki

Patent number: 7581937Abstract: A compressor having a sealed container; a cylinder in which a compression space is constituted; a suction port and a discharge port which communicate with the compression space in the cylinder; a support member which closes an opening of the cylinder; a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member; a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center; a vane which is disposed between the suction port and the discharge port to abut on one surface side of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber. A pressure of the compression member on the other surface side of the compression member is set to a value which is lower than tat of a pressure in the sealed container.Type: GrantFiled: June 13, 2007Date of Patent: September 1, 2009Assignee: Sanyo Electric Co., Ltd.Inventors: Takahiro Nishikawa, Hirotsugu Ogasawara, Takao Kanayama, Yoshiaki Hiruma, Manabu Takenaka, Masazumi Sakaniwa, Akira Hashimoto, Junichi Suzuki

Patent number: 7481635Abstract: A compressor having a compression element with a cylinder in which a compression space is constituted, a suction port and a discharge port which communicate with the compression space in the cylinder, a support member which closes an opening on the cylinder and a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member. A compression member, whose one surface crosses an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and is disposed in the cylinder to be rotated by the rotary shaft, compresses a fluid sucked from the suction port to discharge the fluid via the discharge port. A vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member partitions the compression space in the cylinder into a low pressure chamber and high pressure chamber.Type: GrantFiled: September 7, 2005Date of Patent: January 27, 2009Assignee: Sanyo Electric Co., Ltd.Inventors: Takahiro Nishikawa, Hirotsugu Ogasawara, Takao Kanayama, Yoshiaki Hiruma, Manabu Takenaka, Masazumi Sakaniwa, Akira Hashimoto, Junichi Suzuki
