Patent number: 6338617Abstract: A helical-blade fluid machine maintains a low-pressure atmosphere in a closed casing (1) and secures a proper lubrication state for a compression mechanism (9). The fluid machine has a drive mechanism (7) that is installed at an upper or lower part of the casing and consists of a stator (11) and a rotor (15). The compression mechanism is installed at the other part of the casing. The compression mechanism has a cylinder (23) and a roller (25), which is swayed with respect to the cylinder by the drive mechanism. A helical blade (39) having unequal pitches is arranged on the roller, to define compression chambers (41). This arrangement lowers the head of lubricant. An intake pipe (5) feeds gas into the casing so that a low-pressure atmosphere fills the casing.Type: GrantFiled: October 27, 2000Date of Patent: January 15, 2002Assignee: Kabushiki Kaisha ToshibaInventors: Makoto Hayano, Hirotsugu Sakata, Akira Morishima, Masao Ozu

Patent number: 5240389Abstract: In a scroll type compressor, a revolving scroll having a disc portion and a blade portion is engaged with a stationary scroll having a disc portion and a blade portion. A gas is introduced from the outer peripheral portions of these scrolls and compressed in a pair of compression chambers defined between the scrolls, and a compressed gas is discharged. A first inlet and a second inlet, which are connected by a communication path, are formed at positions corresponding to the compression chambers, where the gas is compressed. Release means is provided between one of the compression chambers and a gas suction unit. The release means returns part of the gas in one of the compression chambers directly to, and part of the gas in the other compression chamber via the first and second inlets, the communication path and the one of the compression chambers to, the gas suction unit simultaneously by equal degrees.Type: GrantFiled: July 13, 1992Date of Patent: August 31, 1993Assignee: Kabushiki Kaisha ToshibaInventors: Satoru Oikawa, Toshinobu Inoue, Akira Morishima, Yutaka Sasahara
