摘要： A seal for reducing leakage about a rotating shaft having an axis includes a rotating component configured to be positioned radially outward from and surround the rotating shaft, and including a rotating cylinder defining an annular oil chamber for receiving oil. The seal also includes a static component including a sealing plate configured to extend into the annular oil chamber such that the oil fills a gap between the sealing plate and the rotating cylinder to reduce air leakage between the rotating component and the static component in response to rotation of the rotating component.

摘要： A non-contact seal for rotatable shafts includes a stator ring and a rotor ring with internal pumping discs. Each of the, the stator ring pumping discs, and the rotor ring is split diametrically into two halves for mounting on a rotatable shaft at an intermediate station without having access to the end of the shaft or without having to remove other components. Various sealing components are employed between the split rings to prevent fluids within the seal from leaking out.

摘要： This invention sets forth a commercially viable diesel combustion system that meets environmentally acceptable levels of NOx emissions (i.e. 0.2 g/bhp-hr or lower across a full map of engine speeds and loads) without the need for use of NOx aftertreatments, and simultaneously maintains engine-out PM emissions relatively close (e.g. with smoke levels at or below 3 BSN) to environmentally acceptable PM post-aftertreatment levels. The invention achieves these results by operating within a unique combination of parameters. These parameters comprise: (1) charge-air oxygen concentration below 16%, preferably between 10% and 15%, more preferably between 11% and 14%, and most preferably between 12% and 13.5% for virtually all engine operating conditions (but not necessarily at no-load or low load conditions), (2) fuel injection pressures at or exceeding 1800 bar, preferably exceeding 2100 bar, more preferably exceeding 2300 bar, and most preferably exceeding 2500 bar, at most engine speeds and loads, and (3) charge-air mass/fuel mass ratio between 25:1 and 45:1 for medium and high loads. Furthermore, the system is preferably run continuously slightly lean of stoichiometry, providing just enough excess oxygen to facilitate completeness of combustion and to maintain an exhaust oxygen level sufficient for continuous trap regeneration at a balance point in operation.

摘要： A slinger for use between a housing and a rotatable member passing therethrough includes an engaging member for mounting on the rotatable member, a slinger portion extending radially outward from the engaging portion, and a sealing portion generally axially extending from the slinger portion wherein the sealing portion extends radially outward when subjected to centrifugal force caused by rotation of the rotatable member to form a secondary seal. The slinger may be formed of a translucent polymer to facilitate a visual inspection of a primary seal located behind the slinger.

摘要： Two seal elements are respectively mounted on generally coaxial relatively rotatable members so that each seal element is capable of relative radial movment with respect to its associated member. One of the seal elements is mounted on its associated member in such a manner that they remain coaxial. The seal elements have confronting radially spaced apart surfaces which are so configured that together they define a hydrodynamic gas bearing. The arrangement is such that upon the relative rotation of the members said seal element which is mounted so as to remain coaxial with its associated member hydrodynamically supports the other seal element so that they remain coaxial.

摘要： A sealing device for rotary machines containing hydraulic fluid, such as centrifugal pumps, compressors, steam turbines and the like. An annular gasket/valve has a flexible lip which seals around the pump or other type machine shaft when the machine is inoperative. An annular sealing chamber is defined between the gasket/valve and an annular cavity defined inside a hollow rotary body fixed around the end of the shaft to be sealed. When the machine shaft rotates at normal speed, the sealing chamber is filled with liquid so that leakage flow is delivered to the annular cavity whereby a liquid ring is formed by centrifugal force around the outer periphery of the cavity. Recovery means in the form of a pitot tube keeps the depth of the liquid ring constant and restores excess liquid to the sealing chamber.
