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: Fixed scrolls 4, 5 are supported so to be movable axially relative to an orbiting scroll 6, so that a proper space is kept between wraps 4a, 5a and 6a to avoid an excessive load in the contacting area. Further, an end portion of an outer curve of the wrap 6a of the orbiting scroll 6 is formed to come close to or coincide to an outer edge of a panel 6f of the orbiting scroll 6 and an Oldham's coupling is accommodated in a concave groove 6e formed on an outer circumference surface of the panel 6f, so that the size of the scroll compressor is reduced.

Abstract: A compressor may include a first compression member, a second compression member, and a motor assembly. The second compression member is movable relative to the first compression member and cooperates with the first compression member to define a compression pocket therebetween. The motor assembly drives one of the first and second compression members relative to the other one of the first and second compression members. The motor assembly includes a stator and a rotor. The rotor is rotatable relative to the stator about a rotational axis. The stator surrounds the rotational axis. The rotor may include magnets that are arranged around the rotational axis. The magnets may be spaced apart from the stator in an axial direction that is parallel to the first rotational axis.

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 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 pump. 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.
