摘要： A scroll type fluid displacement apparatus is disclosed which includes a pair of scrolls each having a circular end plate and spiral element extending therefrom. The scrolls are maintained at an angular and radial offset so that both spiral elements interfit to form a plurality of line contacts to define at least one pair of sealed off fluid pockets. Upon relative orbital motion of the scrolls, the line contacts shift along the spiral curved surfaces of the spiral elements to thereby change the volume of the fluid pockets. In particular, according to the present invention, the thickness of the spiral element of the orbiting scroll is gradually from the inner end of the spiral element to its outer end to increase the mechanical strength of the spiral element at its central portion while avoiding an increase in the centrifugal force generated by the orbiting scroll during orbital motion. On the other hand, the thickness of the spiral element of the other scroll, i.e., the fixed scroll, is gradually increased from the inner end of the spiral element to its outer end to compensate for the change in shape of the facing spiral element of the orbiting scroll.

摘要： A scroll type fluid displacement apparatus, in particular, a compressor unit is disclosed. The unit includes a housing, a pair of scroll members which are comprised of an end plate and a spiral wrap extending from one surface of the end plate. Both wraps interfit to make a plurality of line contacts between their spiral curved surfaces. A driving mechanism and a rotation preventing mechanism are connected to one of the scroll members to effect relative orbital motion while rotation of the scroll member is prevented. A turning mechanism is associated with one of the scroll members to selectively turn the scroll member and vary the angular offset between the wraps, whereby the compressive effect of the scroll members can be controlled independently of the operation of the driving mechanism.

A fixed scroll is joined with the housing and has a first circular end plate from which a first wrap extends. An orbiting scroll has a second circular end plate from which a second wrap extends. The first and second wraps interfit at an angular and radial offset to make a plurality of line contacts to define at least one pair of sealed off fluid pockets. A driving mechanism, which includes a drive shaft, is operatively connected to the orbiting scroll to effect the orbital motion of the orbiting scroll at radius Ror, while the rotation of the orbiting scroll is prevented by a rotation preventing/thrust bearing device, whereby the fluid in the fluid pockets moves inwardly or outwardly and changes in volume. The center of the first circular end plate is aligned with the center line of the housing and the center of the first wrap is radially offset from the center of the first circular end plate by the distance 1/2 Ror.

摘要： A fluid displacement apparatus is disclosed. The apparatus includes a housing having a front end plate, a fixed member and an orbiting piston member. The fixed and orbiting piston members interfit to make a plurality of line contacts to define a sealed off fluid pocket. A driving mechanism, including a drive shaft, is disposed within the housing and is operatively connected to the orbiting piston member to effect the orbital motion of the orbital piston member by the rotation of the drive shaft. The drive shaft is rotatably supported by the front end plate through a bearing. An annular sleeve projecting axially from a front end surface of the front end plate surrounds the drive shaft. A pulley member is fixed on an axial end of the drive shaft which extends from the sleeve and is rotatably supported by the sleeve through a bearing on the outer surface of the sleeve. The drive shaft is thus rotatably supported by the front end plate through two bearings, one within the front end plate and the other on the outer surface of the sleeve.

The most inwardly placed hole is placed at a location defined by involute angles within the area defined by .phi.end-2(n-1).pi.>.phi.1>.phi.end-2n , where .phi.end is the final involute angle of the wrap which extends from the end plate having the holes, .phi.1 is the involute angle at which the hole is placed and n is the amount of pairs of holes. The most outwardly placed hole is placed at a location defined by involute angles within the area defined by .phi.n-1+2.pi.>.phi.n>.phi.end-2.pi.. The intermediate holes are located within an area defined by .phi.k-1+2.pi.>.phi.k>.phi.k+1-2.pi., where .phi.k is the involute angle at which hole kth from the most inwardly placed hole is located. A control mechanism controls the opening and closing of the holes to thereby control the capacity or displacement volume of the compressor.

摘要： A scroll type fluid displacement apparatus including a housing, a pair of scroll members each comprising an end plate and a spiral wrap means projecting from one surface of the end plate. Both wrap means are interfitted to make a plurality of line contacts between them, and a driving mechanism including a drive shaft is connected to one of the scroll members to effect orbital motion thereof relative to the other (fixed) scroll member while rotation of the orbiting scroll is prevented. The center portions of the wrap means are made thicker than the remaining portions thereof, the center portions extending substantially from the inner ends of the wrap means outwardly at least throughout the portions thereof which contact one another when the two innermost fluid pockets are merged into a single fluid pocket to form the high pressure space near the center of the scroll members. This construction insures sealing of the high pressure space from adjacent fluid pockets, keeping volumetric efficiency and horsepower requirement of the unit to a certain level under a limited accuracy of machining of the spiral elements.
