摘要： A seal packing assembly for a hydraulic pump includes a plurality of annular dynamic seals disposed within annular grooves circumferentially defined in the annular bore, a packing gland circumferentially housing a section of the plunger, and a plurality of seal manifolds distributed and defined within the packing gland, each seal manifold defining a port at one end exposed to the pumping fluid and further defining a clean lubrication fluid inlet proximate to a second end, the fluid inlet coupled to a lube pump via a check valve, where the clean lubrication fluid housed in the seal manifolds is maintained at a constant pressure. Each seal manifold includes a piston disposed within the seal manifold having a first end configured with a first surface area to interface with the pumping fluid and a second end configured with a second surface area to interface with the clean lubrication fluid, and a fluid port configured to provide fluid communication between the seal manifold and the annular grooves of the annular dynamic seals.

摘要： An intershaft seal assembly for use between a rotatable outer structure and an inner structure within a turbine engine is presented. The assembly includes a primary sealing ring, a translatable carrier, a secondary sealing ring(s), a lower-pressure chamber, a higher-pressure chamber, a first channel(s), and a second channel(s). The primary ring is disposed within and extends from a circumferential groove about the carrier so as to sealingly engage the rotatable outer structure. The primary ring rotates within the groove and with the rotatable outer structure. Each secondary ring is interposed between the carrier and the inner structure. The carrier slidingly contacts the secondary ring(s). The lower-pressure chamber is generally defined by the carrier and the inner structure adjacent to a higher-pressure side. The higher-pressure chamber is generally defined by the carrier and the inner structure adjacent to a lower-pressure side. Each first channel traverses the carrier so that a gas from the lower-pressure side may enter the lower-pressure chamber. Each second channel traverses the carrier so that a gas from the higher-pressure side may enter the higher-pressure chamber. The sum of the translation-resistant forces (FTTR) encountered by the carrier is less than the translation-resistance force (FTR) encountered by the primary seal ring.

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.
