| 241 | Scroll compressor | US10058731 | 2002-01-30 | US20020102174A1 | 2002-08-01 | Kazutaka Suefuji; Hideaki Ikeda; Junichi Ikeda |
| There is provided a scroll compressor comprising: a fixed-side member comprising a casing and a fixed scroll member provided in the casing; a driving shaft rotatably provided in the casing; an orbiting scroll member orbitably provided at a distal end of the driving shaft; a suction opening provided in the fixed-side member; and a discharge opening provided in the fixed-side member. Each of the scroll members includes an end plate and a spiral wrap portion standing on the end plate. The wrap portion of the orbiting scroll member is adapted to overlap the wrap portion of the fixed scroll member so as to define a plurality of compression chambers. The suction opening communicates with the outermost compression chamber, and the discharge opening is adapted to discharge a compressed gas from an inner compression chamber. A seal member comprising an elastic member is provided around an outer circumferential surface of the orbiting scroll member, so as to seal the compression chambers relative to outside air between the orbiting scroll member and the fixed-side member. The seal member has an opening on a radially inner side thereof and has a generally U-shaped cross-section. | ||||||
| 242 | Suction mechanism of a fluid displacement apparatus | US569451 | 1995-12-08 | US5660538A | 1997-08-26 | Akiyoshi Higashiyama; Masaaki Fujita |
| A fluid displacement apparatus includes a housing having a fluid inlet and fluid outlet. A suction chamber is formed between the first end of the displacement mechanism and the housing and communicates with the fluid inlet port. A discharge chamber is formed between the second end of the displacement mechanism and the housing and communicates with a hollow space. The hollow space is created between the inner block and the housing and communicates with the outlet port. Sealing devices are disposed between the suction chamber and the fluid inlet port for sealing the mating surfaces between the suction chamber and the fluid inlet port. The suction mechanism of the fluid displacement apparatus is thus easily assembled. | ||||||
| 243 | Scroll type compressor with sealing structure for fixed scroll end plate | US177117 | 1988-04-04 | US4913635A | 1990-04-03 | Yoshihiro Ochiai; Masashi Yaguchi; Yoshio Kimura |
| A scroll type compressor includes a housing having an inner chamber and fluid inlet and outlet ports connected to the inner chamber. A fixed scroll is mounted within the housing and has a circular end plate from which a first spiral element extends. An orbiting scroll is also mounted within the housing for orbital motion with respect to the fixed scroll, and includes a circular end plate from which a second spiral element extends. The fixed scroll and the orbiting scroll are maintained angularly and radially offset from each other so that the spiral elements interfit to form a plurality of line contacts between their spiral curved surfaces which seal-off and define at least one pair of fluid pockets. The orbital movement of the orbiting scroll relative to the fixed scroll shifts the line contacts along the spiral curved surfaces of the spiral elements which changes the volume of the fluid pockets. The end plate of the fixed scroll partitions the inner chamber of the housing into a suction chamber and a discharge chamber. A sealing structure is disposed between the inner peripheral wall of the housing and the outer peripheral surface of the end plate of the fixed scroll. The sealing structure includes an annular cut-out portion, having an L-shaped sectional side view, formed in the outer peripheral surface of the end plate of the fixed scroll, an annular ridge formed in the inner peripheral wall of the housing and an O-ring seal element disposed between the annular cut-out portion and the annular ridge. | ||||||

| In a vane-type compressor, the slotted rotor includes resilient slot sealing means in the form of leaf springs. Each spring extends between consecutive slots and has curved end portions projecting into the slots and sealingly engaging opposite sides of corresponding vanes. | ||||||
| 246 | Seal for closing a cavity | US468092 | 1983-02-22 | US4465286A | 1984-08-14 | Brian C. Deem; Ralph G. Eslinger |
| A seal assembly (54) for closing a cavity (55) between a rotor (24), a bearing retainer (38) and a crankshaft (80) to retain a fluid therein for lubricating bearings (48, 50, 90) associated with the crankshaft (80). Seal assembly (54) has a disc (72) with a first resilient member (56) that engages the rotor surface (44) and a second eccentrically positioned resilient member (62), that engages surface (65) on bearing retainer (38). Disc (72) which is attached to crankshaft (80) rotates with ring gear (36) around pinion (32) to maintain a sealed cavity (55) even though the first and second resilient members (56 and 62) rotate on their respectively sealing surfaces (44 and 65) with different revolutions per minute. | ||||||
