摘要： A sealing arrangement having inboard and outboard dynamic seals in a housing separated by a barrier fluid and having a sealed relationship with a relatively movable bearing-guided shaft. A bearing chamber having bearing lubricant exposed to the inboard dynamic seal. The inboard dynamic seal is a hydrodynamic seal having a hydrodynamic pumping action in response to relative rotation between the shaft and the inboard dynamic seal. The hydrodynamic pumping action forcing a film of the bearing lubricant between the inboard dynamic seal and the shaft. The hydrodynamic pumping-related leakage of the inboard dynamic seal being returned to the bearing chamber in which the shaft guidance bearings are located.

摘要： A seal assembly for a dual-flow compressor is provided. The seal assembly may include an annular body disposed about a rotary shaft between a first compression assembly and a second compression assembly of the dual-flow compressor. An inner radial surface of the annular body and an outer radial surface of the rotary shaft may at least partially define a radial clearance therebetween. The annular body may have a first seal section and a second seal section at a first axial end portion and a second axial end portion thereof, respectively. The first and second seal sections may at least partially define a cavity therebetween. The seal assembly may also include a reference line communicably coupling the cavity with an inlet of the first compression assembly and configured to at least partially generate a pressure differential between the cavity and an outlet of the first compression assembly.

摘要： A sealing arrangement for the sealed leadthrough of rotating shafts (2) through housing bores of housings (1) comprises at least one lip seal (3, 8, 14, 15) with a sealing lip that faces toward the area normally under higher pressure. In order to extend substantially the area of application of sealing arrangements with lip seals and by doing so, to make use of the sealing arrangement to achieve its advantages of being more economical, more durable also at pressure peaks, easier to install, and easier to maintain, also at higher pressures and pressure fluctuations, the lip seal (3, 8, 14, 15) on the side (5) facing the area with higher pressure is under a constant pressure that is higher than the highest pressure occurring inside the housing (1), and a gap (7, 10) that throttles the outflow is provided between this area and the inside of the housing.

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 sealing mechanism comprises a support member forming part of the semiconductor producing apparatus which has a vacuum chamber, a rotation shaft rotatably received in the support member, and at least three seal rings axially spaced apart from each other between the support member and the rotation shaft to form a first fluid chamber close to the atmosphere and a second fluid chamber close to the vacuum chamber. The first fluid chamber is vacuumized to have a first pressure, and the second fluid chamber is also vacuumized to have a second pressure which is lower than the first pressure. The first and second fluid chambers work together to enhance the sealing performance of the sealing mechanism.

摘要： A device for drilling a bore hole in the ground comprised of a rotary drive head and a hollow Connecting Rod Assembly on which the rotary drive head acts and which can be lowered into the hole in the ground through the rotary drive head. A tool head with several Drilling Hammers that work downwards and that are operated with a fluid driving medium are provided on the lower end of the Connecting Rod Assembly. In the case of an initial design form, a Rotary Connecting Head is located in the upper area of the Connecting Rod Assembly; a fluid driving medium under high pressure can be supplied to the upper end of the Connecting Rod Assembly through the rotary connecting head, and the rotary connecting head has a transition chamber in its Housing, sealed in the axial direction towards both sides and connected to an external Supply Line for the fluid operating medium. Several ring seals, grouped in stages in the axial direction and hydraulically pressure-balanced stage-by-stage, are provided in each case on both sides of the transition chamber. In the case of a second design form, the driving is done in an oscillatory fashion around a limited angle, which permits the use of flexible supply lines for the feed-in of scavenging and operating media and the discharge of excavated material.

摘要： A fuel injector includes an injector body with a plunger bore that opens to a nozzle outlet. A plunger having a pressure face and a side surface is positioned to reciprocate in the plunger bore between an advanced position and a retracted position. A portion of the plunger bore and the plunger define a fuel pressurization chamber that opens to the nozzle outlet. A needle valve is positioned in the injector body adjacent the nozzle outlet and is moveable between an open position which opens the nozzle outlet and a closed position in which the nozzle outlet is closed to the fuel pressurization chamber. An O-ring is in contact with the side surface of the plunger and the plunger bore on the injector body and serves to seal against fuel leakage past the plunger. Pressure acting on the O-ring is attenuated by providing either a pressure accumulation volume between the pressure face end of the plunger and the O-ring and/or a pressure release passage that opens the plunger bore to a low pressure return line below the O-ring.
