摘要： Non-contacting cartridge shaft seals prevent leakage loss of process gases in an “oil free” rotary screw compressor or blower, while simultaneously preventing ingress of lubricating oil to the pumping chamber, allowing the compressor/blower to generate process pressure differentials without oil contamination. A compact unitized seal cartridge assembly is provided in the end plates of the pump housing. One of the rotor shafts extends through an aperture in the end plate or housing, between the pumping chamber and oil-lubricated gear/bearing cases. Internal elements have the ability to self-align radially achieving essential concentricity with shaft rotational axes. The rotor shafts or sleeves non-contact relationship during operation allow increased ranges of shaft rotational speeds. Air seal elements restrict flow of process air from the pumping or compression chamber, and oil seal elements with a directional spiral groove on the inside diameter prevent the leakage of lubricating oil to the process or atmosphere.

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 thruster valve for controlling a flow of high temperature fluid, comprising a valve casing, a graphite liner, a drive rod, and at least one relief hole. The graphite liner is disposed in a through hole within the valve casing. The drive rod being slidably received in drive rod through holes within the graphite liner, such that a seal is formed and maintained between the drive rod and the graphite liner. The drive rod is arranged so as to be driven in an axial direction by an actuator attached to an end of the drive rod arranged outside the valve casing. At least one of the relief holes is formed to extend through the graphite liner and valve casing to communicate the cavity with the exterior of the valve casing provide a drain passage. Thus, leakage of the high temperature fluid is prevented.

摘要： A reciprocable piston comprises a cylindrical body reciprocable within a hollow cylinder and at least two spaced ring seals disposed around the circumference of the cylindrical body. Within the cylindrical body there is a scavenging system that comprises: an internal chamber that is in fluid communication with a space between the spaced ring seals; and a one-way fluid passage that allows one-way fluid flow from the internal chamber to the cylinder chamber when fluid pressure within the internal chamber is greater than fluid pressure within the cylinder chamber. A method of scavenging fluid comprises collecting fluid that leaks by a piston seal and returning the collected fluid to the cylinder chamber from which it originated, through a scavenging system disposed within the piston.

摘要： A shaft sealing module is proposed for sealing a shaft which extends driving rotationally from a normal pressure chamber into a high vacuum chamber. It is essential for the shaft sealing module according to the invention that the dynamic seal of the shaft takes place not on the shaft itself but on a bushing mounted rotatably in a housing through which is guided a shaft and which is held on the shaft in friction connection, statically sealed, by elastic rings so that the bushing rotates with the shaft. The dynamic seal between the bushing and the housing is achieved by several radial shaft sealing rings which are preferably arranged so that between them is provided a prevacuum chamber with intermediate evacuation so that a two-stage dynamic seal is provided, where the prevacuum acts on the static seal between the bushing and the shaft in the sense of a gas penetration barrier towards the high vacuum chamber.

摘要： Turbocharger comprising a rotor shaft (5), a turbine housing (2), a compressor housing (3) connected to the turbine housing (2), and including at least one air supply channel (13′) for supplying air to be compressed and at least one discharge channel (11) for delivering compressed air. One end of the rotor shaft projects into the compressor housing and supports a compressor rotor (21). A bearing (12) in the region of the compressor rotor supports the rotor shaft, and forms a bearing gap.

A suction channel (33,34) is connected to a vacuum source and sucks gas out of this intermediate space.
