| 81 | Tension ring for compressor vane | US3790148D | 1972-03-31 | US3790148A | 1974-02-05 | BELLMER T |
| A hollow cylindrical body and two end walls define a compression chamber in which a rotor is disposed. Hubs are formed on the outer sides of the end walls for receiving a pair of tension rings. A vane is disposed in a radial opening formed in the body and engages the rotor for dividing the chamber into high and low pressure sides. The vane is held in engagement with the rotor by a pair of coil springs disposed between the outer end of the vane and the tension rings.

| The vane pump assembly includes a housing with an inner wall that surrounds an open chamber. A rotor is rotatably disposed in the open chamber and has a circular shape when viewed in cross section. A first pair of vanes are received in the rotor and are operably connected with one another by a first bell crank which is pivotable about a pivot axis such that movement of one vane inwardly into the rotor causes the other vane to move outwardly out of the rotor to maintain both vanes in contact with the inner wall as the rotor rotates relative to the housing during operation of the vane pump assembly. | ||||||

| A compressor includes a drive shaft, a housing, an annular rotor, and cradles. The rotor has cradle windows. The rotor can rotate within the rotor chamber together with the drive shaft while being in sliding contact with the housing at the circumferential surface. The cradles are provided in the cradle windows to be pivotable about pivot axes. When pivoting, the cradles maintain the compression chambers in an airtight state by being in contact with the housing at pivoting ends of the cradles, the pivoting ends extending along the direction parallel to the axis. The rotor chamber includes an outer operation chamber located on the outside of the rotor, and an inner operation chamber located on the inside of the rotor. The cradles, and the outer operation chamber and/or the inner operation chamber form the compression chambers, the volumes of which are varied by the rotation of the rotor. | ||||||

| A single-screw compressor includes a casing, a screw rotor accommodated in the casing, a gate rotor, and a gate rotor supporting member rotatably supporting the gate rotor. The gate rotor includes a plurality of flat-plate-shaped gates formed in a radial pattern and meshing with a helical groove of the screw rotor. Fluid in a compression chamber defined by the screw rotor, the casing and the gates is compressed when the screw rotor is rotated. The gate rotor supporting member includes a gate supporting portion supporting each gate from a back surface side. The gate rotor and the gate rotor supporting member form a gate rotor assembly including a pressure introduction channel configured and arranged to introduce a fluid pressure on a front surface side of each gate into a gap between a back surface of the gate and the gate supporting portion. | ||||||

| 99 | Scroll fluid machine | US11319120 | 2005-12-27 | US07357627B2 | 2008-04-15 | Kazuaki Sato |
| In a scroll fluid machine, a stationary scroll fixed to a housing engages with an orbiting scroll to form a sealed chamber between the orbiting and stationary scrolls. Fluid in the sealed chamber is compressed or decompressed with revolution of the orbiting scroll with respect to the stationary scroll. A plurality of self-rotation preventing devices are provided on the orbiting scroll to prevent the orbiting scroll from rotating on its own axis. The self-rotation preventing device comprises an eccentric tube connected to a main shaft fitting in the housing, and an eccentric shaft fitted in a bearing plate. The eccentric tube is eccentrically revolved with respect to the main shaft thereby allowing engagement of the orbiting scroll with the stationary scroll to be adjusted. | ||||||

| The present invention provides a scroll pump device comprising external and internal scroll members, and wherein the scroll pump device is separated into inner and outer zones. The flow streams in the two zones are kept separate, and each stream may have different chemical compositions and flow rates. The scroll pump system can provide both vacuum and pressure flow streams in a compact lightweight package, and may be used for the separation and concentration of oxygen from atmospheric air, for use, inter alia, in portable medical systems. | ||||||
