    摘要： Scroll pumping apparatus includes a first scroll element and a second scroll element; a drive mechanism operatively coupled to the second scroll element for producing orbiting motion of the second scroll element relative to the first scroll element, the drive mechanism having an axis of rotation; and an isolation element to isolate a first volume and a second volume in the scroll pumping apparatus. The isolation element includes a first resilient annular member coupled, directly or indirectly, to the first scroll element, a second resilient annular member coupled, directly or indirectly, to the second scroll element, and a tubular member coupled between the first and second annular members.

    摘要： A device which is used to guide at least two flow media having different pressures with a shaft or similar force-transmitting element, and a pressure insulating element such as a housing surrounding the shaft or similar. Areas arranged next to each other in the direction of the axis are determined between the force-transmitting element and the pressure-insulating element by sealing elements; at least one of the preferably magnetofluidic sealing elements is leakage-free, and two areas for fluids (A, B) having different pressures flank an area for an auxiliary liquid (H), whereby said area is subdivided by a device into two partial areas for two different pressure areas. A conveying medium is allocated to the area at high pressure and ambient air is allocated to the area at low pressure. The auxiliary liquid (H) is a carrier oil of the magnetofluid, optionally a silicon oil, allocated to the sealing element.

    摘要： A rotary fluid machine is provided that includes a rotor rotatably housed within a casing, a hollow rotating shaft (113) that rotates integrally with the rotor, and a fixed shaft (102) that is relatively rotatably fitted into the inner periphery of the rotating shaft (113); in which the rotating shaft (113) is formed by shrink-fitting an outer sleeve (21) made of metal around the outer periphery of an inner sleeve (85) made of ceramic, etc. having a lower coefficient of thermal expansion than that of metal, and the fixed shaft (102) is formed by shrink-fitting an outer sleeve (88) made of metal around the outer periphery of an inner sleeve (87) made of ceramic, etc. having a lower coefficient of thermal expansion than that of metal. Since thermal expansion of the outer sleeves (21, 88) fitted around the outer peripheries of the inner sleeves (85, 87) is suppressed due to residual tensile stress of the outer sleeves (21, 88), intimate contact between the outer sleeves (21, 88) and the inner sleeves (85, 87) can be maintained.

    摘要： A viscous seal for fluid transfer devices that deviates from the conventional wisdom of avoiding contact between the seal and a rotating drive shaft of the fluid transfer device. Instead of avoiding contact, contact between the seal and drive shaft is used to effect axial alignment of a sealing sleeve with the shaft. As a result, the viscous seal is compliant in that the sealing sleeve can follow the axis of the drive shaft. Accordingly, the sealing sleeve can fit snugly around the drive shaft for more effective prevention of leakage of low or any viscosity fluid along the drive shaft, but without any significant radial load being applied to the sealing sleeve that might cause undue wear or damage due to galling.

    摘要： A hydraulic pump includes a pump body having a bearing hole and formed with a seal chamber at an end of the bearing hole and an oil groove therein, the oil groove ensuring hydraulic communication between the pump unit and the seal chamber, a pump cover attached to the pump body to define a concavity for accommodating a pump unit, and a drive shaft arranged through the bearing hole of the pump body. A bearing bush, which is arranged through the bearing hole of the pump body to support the drive shaft, includes bush lugs disposed in the axial direction of the bearing hole of the pump body. Two of the bush lugs disposed at both ends of the bearing bush have seams located circumferentially distant from each other.
