Patent JP-H01257783-A (JP)
Title: Scroll compressor
Inventor: FUKANUMA TETSUHIKO
IPC: F04C18/02
Filed: 1988-04-06
Abstract: PURPOSE:To increase wall thickness while reducing the degree of winding on scroll tongue portions by forming the tongue portions of both scrolls using elliptical arcs on a short axis side. CONSTITUTION:As a movable scroll 2 revolves, the connecting portions (contact point P8) of the elliptical arc D1 and a track curve D2'' of both fixed and movable scrolls 1, 2 agree with each other and, from this time of agreement, the torque portions of both scrolls 1, 2 are mutually separated. The torque portions of both scrolls are formed by using the elliptical arc D1 of a short axis side. Thereby, the length of the long axis direction of the track curve D2'' can be made sufficiently large without need for separating the position of the contact point P8 between the elliptical arc D1 and the track curve D2'' from a tangent l2. Hence, wall thickness can be increased while keeping the degree of winding high.

Title: Diaplacement type compressor
Inventor: YAMAMOTO MITSUSACHI
IPC: F04C23/00
Filed: 1989-04-05
Abstract: PURPOSE:To reduce number of parts in two-stage compression and to achieve a compact size by using a screwcompressor in a low pressure stage and placing a different movable vane type compressor or the like of other compressing system as a high pressure stage in a rotor. CONSTITUTION:Air introduced in a compressor passes through an inlet passage 13, is sucked in the grooves of screw rotors 3, 4, compressed as the rotors 3, 4 are rotated and discharged to a discharge port 14 when prescribed pressure is obtained. This discharge port 14 is connected to an introducing passage 15. The air is sucked in gaps between a movable vane 10, a fixed rotor 9 and the rotors 3, 4 from the inlet port 16 of a movable vane type compressor. As the rotors 3, 4 are rotated, the movable vane 10 attached thereto turns around the fixed rotor 9 to gradually reduce a space 10 so as to compress the air an discharge it under a prescribed pressure from a discharge port 17. In such a way, a compressor main body is built in a screw rotor, so that it can have substantially the same size as that of a one-stage compressor.
