Abstract: A scroll compressor is provided with idler shafts and scroll assemblies, both of which are two-piece assemblies. The two pieces of the idler shaft are made independently of each other and each includes an axis of symmetry which facilitates forming, or partial forming, of the parts on a lathe. The two parts, each of which includes a shaft, are then joined together with the shafts offset from each other to form the proper eccentricity in the idler shaft. The scroll assemblies are made by first forming a base plate for the desired scroll and then forming an eccentric groove in the base plate. An involute, which is formed to correspond to the groove is inserted in the base plate groove. The involute has grooves on both of its end surfaces to allow the same involute to be used for both the fixed and orbiting scroll plate.

Abstract: Axial compliance/sealing means are provided for scroll-type apparatus. These means comprise seal elements associated with the involute wraps which are urged by an axial force to make sealing contact with the end plates of the opposing scroll members. The axial force may be pneumatically or mechanically applied and the resulting axial contact is of such a nature as to maintain the integrity of the radial sealing within the apparatus. The use of the axial compliance/sealing means allows the contacting surfaces through which radial sealing is effected to be machined to conventional accuracy, and provides automatic compensation for temperature differentials within the apparatus as well for any uneven wear of the scroll members.

Abstract: A positive fluid displacement apparatus employing scroll members having interfitting spiroidal wraps angularly and radially offset such that as one of the scroll members is orbited, moving fluid pockets of variable volume and different fluid pressures are formed. Axial load carrying of the scroll members is achieved pneumatically through the introduction of a fluid into a pressurizable fluid chamber within the housing and in axial force applying relationship with the orbiting scroll member. The pressurizable fluid chamber may constitute essentially all or only a part of the internal volume of the housing and it is isolated from the fluid pockets. This type of axial load carrying materially reduces the loads which must be carried through the crankshaft and decreases the size and complexity of the bearings. The apparatus is particularly well suited to compressors operating at high exhaust pressures.

Abstract: A three stage vacuum pump has three stages of fixed scrolls and orbiting scrolls that operate simultaneously. A motor drives the second orbiting scroll within the third fixed scroll upon three equally spaced idlers. One idler then transmits rotation and torque into the second stage. The second orbiting scroll to has involutes upon both surfaces to engage the second fixed scroll inwardly and the first fixed scroll outwardly. The first fixed scroll has fins upon its back that extend into the atmosphere to transfer heat to air cool the invention. This pump also has a fan accelerating heat transfer. The pump operates the scrolls directly from a motor or from a motor and magnetic coupling so that the atmosphere does not infiltrate the pump.

Abstract: A scroll compressor having improved efficiencies includes a fixed plate having a spiral involute and an orbiting plate having a spiral involute wrap. The fixed and orbiting plates are positioned in a housing such that the spiral involute wraps mesh with each other to define chambers. A sealant being applied to tips and sides of said involute wraps, said sealant substantially is closing any gaps between the tip of the involute wrap and the plate opposing the involute wrap. The sealant is chosen from the group consisting essentially of a grease, a dampening gel, and an epoxy. If a grease is used, then the grease is preferably a low vapor pressure grease. During assembly of the scroll compressor, the sealant is applied to tips and sides of the involute wraps. After the scroll compressor has been assembled, it is run to purge excess sealant, leaving sealant only in the gaps between the two scrolls. If an epoxy is used as a sealant, and the epoxy requires curing, the scroll compressor is disassembled after the initial run and the epoxy is cured. The scroll compressor is then reassembled.

Abstract: A scroll vacuum pump includes a first stage having a first stage fixed plate with a spiral involute, a second stage having a second stage fixed plate with a spiral involute wrap, and an orbiting plate having upper and lower surfaces. An involute spiral extends from the orbiting plate bottom surface to define a first stage orbiting plate and a second involute spiral extends from the orbiting plate top surface to define a second stage orbiting plate. The first stage involute wraps are taller than the second stage involute wraps. Gas is expanded in the first stage and compressed in the second stage. The first stage has an expansion ratio greater than or equal to one and the second stage has a compression ratio greater than or equal to one. However, that the pressure at the second stage exit is less than the pressure at the first stage inlet. To increase the efficiency of the pump, the tip seals of the involute spirals are extended as close as possible to the center of the involute to delay porting of gas by 180° of rotation.

Abstract: The invention comprises a positive fluid displacement apparatus of the scroll type described as a fluid compressor in the exemplary embodiment. The embodiment has single fixed and movable scroll elements in which the latter orbits the former to form variable volume pockets which move from an inlet to an outlet and means are provided for discharging fluid from at least one of the pockets prior to its movement to the outlet port, cooling the vented fluid and returning it to the apparatus for final compression and discharge. Accordingly, by this arrangement, two stages of compression with intercooling are provided in a single apparatus having only a single fixed scroll element and a single movable scroll element.
