摘要： A pressure-actuated shaft seal assembly and associated method for controlling the flow of fluid adjacent a rotatable shaft are provided. The seal assembly includes one or more seal members that can be adjusted between open and closed positions, for example, according to the rotational speed of the shaft. For example, the seal member can be configured to be adjusted according to a radial pressure differential in a fluid that varies with the rotational speed of the shaft. In addition, in the closed position, each seal member can contact a rotatable member connected to the shaft to form a seal with the rotatable member and prevent fluid from flowing through the assembly. Thus, the seal can be closed at low speeds of operation and opened at high speeds of operation, thereby reducing the heat and wear in the seal assembly while maintaining a sufficient seal during all speeds of operation.

摘要： A gasket, sliding about the axis of rotation of a part to be brought closer to or to be spaced apart from another part with which it provides tightness through a pair of lips provided on a ring. The gasket includes a portion of the ring capable of bending to modify the clearance between the corresponding lip and the part, the pressure prevailing in an intermediate cavity, the balance of forces on the joint and hence the clearance and the leak flow rate allowed before the gasket, which is advantageous in particular in a case of ventilation gas for refrigerating an element of the machine in controlled operating conditions.

摘要： A primary object of the present invention is to achieve a high sealing performance, to collect hazardous gas contained in a sealed process fluid, and to realize an easy disposition of a mechanical seal device. A typical configuration is that the end face of a shaft sleeve engages a rotary shaft by a step shoulder of the shaft which is disposed in the sealed fluid side relative to the stationary seal ring, and that the inner diameter of the end face is set larger than the inner diameter of the sealed fluid pressure surface on the back face of the stationary seal ring. This construction makes it easy to dispose a mechanical seal device and with this mechanical seal device, the sealed process fluid is securely sealed.

摘要： A method for controlling fluid leakage between a first pressure region and a second pressure region within a gas turbine engine using a first sealing member and a second sealing member. The first sealing member is movably coupled to a portion of the gas turbine engine, and a space defined generally between a portion of the first sealing member and a portion of the second sealing member fluidly couples the first pressure region to the second pressure region. The method includes moving the first sealing member towards the second sealing member using fluid pressure within a portion of the engine, and, using the first and second sealing members, substantially controlling fluid leakage between the first pressure area and the second pressure area through the space generally without contacting the first sealing member with the second sealing member.

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 method of operating an internal combustion engine wherein intake ambient air is boosted to a higher pressure by passage through at least one compressor and then introduced into the internal combustion engine. Fuel is also introduced into the internal combustion engine for providing combustion in admixture with the air charge at a combustion temperature approximating a target value. Various engine operating parameters, inclusive of torque demand, e.g., accelerator pedal depression, are sensed and the boosted pressure is changed in a manner proportional to a change in the sensed torque demand so as to maintain the combustion temperature at approximately the target value, i.e., below 2100° K.

摘要： A seal construction is provided for sealing a rotating pump shaft against passage of a fluid along its central axis. The seal construction includes front and rear sealing flanges mounted coaxially to and rotatable with the pump shaft. Stationary engaging members are provided adjacent the rear surface of the front sealing flange and the front surface of the rear sealing flange for sealing engagement therewith. A temperature stabilized chamber is provided adjacent each sealing flange including means for recirculating and cooling fluid disposed therein so as to maintain the fluid between adjacent engaging members at a substantially constant temperature thereby maintaining a flatness of the sealing engagement between the sealing flange surfaces and the engaging members. The recirculating/cooling system includes a gland having first, second, third, and fourth fluid passages defined therein.
