  • Patent number: 11047389
    Abstract: A multi-stage vacuum pump, expander, or compressor, that incorporates one or more stages of a fixed scroll(s) and orbiting scroll(s) that operates simultaneously. The motor drives the orbiting scroll(s) within the structure, and the various fixed and orbiting scrolls are arranged for either parallel generation of a vacuum or high pressure gas, or arranged in series for generating of a significantly high vacuum or gaseous pressure, or a combination of parallel arranged and series arranged fixed and orbiting scrolls may be embodied within the structure, operated by a single motor means, in order to attain the high efficiencies of operation as a vacuum pump, or a gaseous compressor, during its functioning. The various combinations of orbiting and fixed scrolls, when arranged as aforesaid, can be reduced in size, or miniaturized, and used in conjunction with small appliances, or even in hand-held instruments, as for example, for use in conducting mass spectrometry, or for other purposes.

  • Patent number: 9885358
    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.

  • Patent number: 8668479
    Abstract: This gas equipment, for other than air, includes a fixed scroll and an orbiting scroll, each having fins upon their back surfaces. The orbiting scroll remains within a housing having fins that engage with the fins on the orbiting scroll. The internal fins of the housing transfer heat from the orbiting scroll to the housing for air cooling by the atmosphere. The spiral arranged fins pump working fluid within the housing to increase heat transfer. The housing may also have an exterior fan. The orbiting scroll receives torque and rotation from a magnetic coupling or magnetic face seal, without a physical connection to a motor, so that the atmosphere does not infiltrate inside the housing. The present invention also has an enclosed inlet plenum to prevent infiltration of the atmosphere into the working fluid.
