| 20090208322 | Gas turbine engine systems and methods involving blade outer air seals - Gas turbine engine systems and methods involving full ring outer air seals are provided. In this regard, a representative blade outer air seal assembly for a gas turbine engine includes a continuous, annular seal body formed of ceramic matrix composite (CMC) material. | 08-20-2009 |
| 20100316485 | TURBOCHARGER - In a turbocharger with an oil thrower | 12-16-2010 |
| 20110318163 | BARREL-SHAPED CENTRIFUGAL COMPRESSOR - In a centrifugal compressor, for the purpose of preventing the positions of a diaphragm and a head flange in a radial direction from moving with respect to a casing, suppressing the generation of an unstable fluid force in a seal and the contact of the seal with a rotor to prevent the unstable vibration of the rotor and enabling an efficient and stable operation even on high-pressure conditions, there is provided a barrel-shaped centrifugal compressor including a casing, a diaphragm located in the casing to define a flow channel, and a head flange attached to the end of the casing by a shear key, wherein in the inner peripheral surface of the casing and the outer peripheral surface of abutment portions of the diaphragm and the head flange in which they are abutted on the inner peripheral surface of the casing, sliding key grooves which are vertical to the surfaces are provided at least two portions in a peripheral direction, and sliding keys are provided in the key grooves. | 12-29-2011 |
| 20110318164 | EXHAUST GAS TURBOCHARGER - The means of sealing the compressor wheel with respect to the bearing housing includes an annular sealing element which forms a sealing boundary face with a shaft edge and to which a spring force is applied in the direction of the shaft edge. The external spring force neither compensates or amplifies the pressure forces acting on the sealing element, irrespective of the direction of the difference in pressure. As a result, the sealing of the oil space in the bearing housing of the exhaust gas turbocharger with respect to the shaft is not influenced, or is influenced only to a small degree, by the pressure fluctuations in the wheel back space of the compressor. | 12-29-2011 |
| 20120003076 | METHOD AND APPARATUS FOR ASSEMBLING ROTATING MACHINES - A method for assembling a rotating machine includes providing a rotating element including a plurality of rotor wheels. The method also includes positioning the rotating element such that at least a portion of a stationary portion extends at least partially about the rotating element. The method further includes assembling an interstage seal mechanism including coupling at least a portion of a first hook device to the rotating element, and also including coupling at least a portion of a second hook device to the first hook device. The first hook device and the second hook device are radially inboard of at least a portion of the stationary portion. | 01-05-2012 |
| 20120128466 | ADVANCED AIR AND OIL CIRCUIT ARCHITECTURE FOR TURBOMACHINE - The present invention relates to a system for lubricating a turbomachine comprising at least one enclosure, called non-ventilated, with members to be lubricated and an air-oil mixture, said enclosure being closed and pressurized using dynamic pressure seals supplied with compressed air to create an airflow from the outside toward the inside of the enclosure, said enclosure comprising an outlet for conveying the air-oil mixture toward an air/oil separator, said separator being provided with an suction function favoring the flow of the air-oil mixture between the enclosure and the separator, characterized in that the lubrication system comprises additional suction means. | 05-24-2012 |
| 20140161589 | BACKUP SEALS IN ROTARY PUMPS - Arrangements for promoting the restriction of fluid flow along a shaft via providing a deformable ring member in an annulus between the shaft and housing. In an initial general condition, the deformable ring member permits free fluid flow in a general direction along the shaft while in a second, constricted condition, the deformable ring closes or blocks a gap or clearance normally conducive to free fluid flow to thereby restrict fluid flow. An actuation medium, which can take any of a very wide variety of forms, preferably promotes constriction of the deformable ring member directly or indirectly. | 06-12-2014 |
| 20140178178 | GAS SEAL ASSEMBLY FOR CRYOGENIC LIQUID TURBOMACHINES - A dry seal apparatus ( | 06-26-2014 |
| 20140356131 | FAN MODULE AND ELECTRIC BLOWER HAVING THE SAME - Disclosed herein is a fan module including an impeller cover having an intake member formed therein and covering one side of a housing, an impeller accommodated within the impeller cover and rotatably coupled to a rotational shaft of a motor accommodated in the housing, and a leakage reduction member positioned in an inner surface of the impeller cover to reduce a flow leakage between the impeller cover and the impeller. | 12-04-2014 |
| 20150354583 | CENTRIFUGAL PUMP WITH GOVERNOR ACTUATED SEAL - The present invention relates to centrifugal pumps, and more specifically to a centrifugal pump device with a governor actuated cartridge seal and a method of attaching a centrifugal pump device with a governor actuated cartridge seal. The centrifugal pump comprises a sealing system that prevents undesirable fluid leaking or air ingestion when in operation while allowing ease of installation and maintenance. The governor actuated cartridge seal automatically increases sealing capabilities by urging a movable seal as a function of impeller or engine drive shaft rotational speed. The governors actuate radially so as to present a minimal profile and therefore not introduce a safety hazard. Scalable weights attached to the governors allow predictable calibration and initialization of the pump under varying hydraulic pressures and rotational speeds. | 12-10-2015 |
| 20160040795 | Check Valve - A check valve includes an internal liquid trap that prevents the backflow of gas and debris from degrading the valve. The internal liquid trap can be formed by internal passages within a valve housing. One embodiment includes three internal passages, an inlet passage, an intermediate passage, and an outlet passage, with connecting passages between each of the inlet passage and outlet package, and the intermediate package. In some embodiments, an internal trap is provided between the intermediate passage and the inlet passage. | 02-11-2016 |
| 20160186769 | Bushing Seal for Use in a Pump - A device is disclosed including a shaft seal made with thermoplastic material formed as a hollow cylinder with an inside diameter and an outside diameter. The hollow cylinder may have multiple passages through the thermoplastic material between the inside diameter and the outside diameter. The multiple passages between the inside diameter and the outside diameter allow fluid under pressure to pass between the inside diameter and the outside diameter through the multiple passages. | 06-30-2016 |
