20100092116 | PRESSURE BALANCED VALVE ASSEMBLY AND AIRCRAFT BUFFER COOLER SYSTEM EMPLOYING THE SAME - A pressure balanced valve assembly is provided. In one embodiment, the pressure balanced valve assembly includes a housing assembly having first and second seats. A flow passage formed through the housing assembly includes a first inlet, a second inlet, and an outlet. A piston is slidably mounted in the housing assembly for movement between: (i) a first position wherein the piston contacts the second seat to restrict fluid flow from the second inlet to the outlet, and (ii) a second position wherein the piston contacts the first seat to restrict fluid flow from the first inlet to the outlet. First and second dynamic seals are mounted in the housing assembly. The first and second dynamic seals sealingly engage first and second portions of the piston over areas substantially equivalent to the sealing areas of the second and first seats, respectively. | 04-15-2010 |
20140301681 | THRUST PLATE INCLUDING COOLING SLOTS - A thrust plate includes an annular-shaped body having a scalloped outer edge that forms a first circumference defined by a first diameter. The thrust plate further includes a plurality of cooling slots formed in a first surface of the body. The cooling slots are formed between each pair of adjacent scallops. A center of each cooling slot extends towards the center of the thrust plate at a common predetermined angle with respect to one another. | 10-09-2014 |

20090263059 | METHOD AND DEVICE FOR LUBRICATING AND COOLING A BEARING THAT IS SUBJECT TO HIGH LOADS - The invention relates to a method for lubricating and cooling a bearing that is subject to high loads and to a device for carrying out said method. The invention is characterized by dissolving a lubricant in a supercritical gas that is cooled down to a low temperature and feeding the gas/lubricant mixture to the baring. The gas/lubricant mixture is relaxed in the bearing area, thereby releasing the lubricant and lubricating the bearing. The now subcritical gas that is cooled down to a low temperature is used for cooling and is discharged to the exterior. The gas used is carbon dioxide (CO | 10-22-2009 |

20140321781 | ARRANGEMENT TO CONTROL THE CLEARANCE OF A SLIDING BEARING - An arrangement to control the clearance of a sliding bearing is disclosed. A sliding bearing arrangement, of a direct driven wind turbine, comprises a bearing. The bearing comprises a first bearing shell and a second bearing shell, whereby the first bearing shell and the second bearing shell are arranged rotatable in respect to each other. A certain predetermined clearance is present between the first bearing shell and the second bearing shell, while the bearing is in rotation. A first circuit comprises a first fluid, while the first circuit is in thermal contact with the first bearing shell. A second circuit comprises a second fluid, while the second circuit is in thermal contact with the second bearing shell. The first circuit and the second circuit are coupled in a way that a difference in the temperature between the first bearing shell and the second bearing shell is compensated via the first and the second fluid, thus the clearance is kept within a predetermined range. | 10-30-2014 |
20150023621 | BEARING FOR A WIND TURBINE - A bearing for a wind turbine, the use of the bearing and a method to control the temperature of the bearing is provided. A bearing for a wind turbine comprises an inner ring and an outer ring. The inner ring and the outer ring are prepared and arranged in a way to rotate with respect to each other. The inner ring comprises at least one channel. The channel is prepared and arranged in a way that air flows along inside the channel so that excess heat of the inner ring is removed by the airflow in the channel. | 01-22-2015 |

20090208156 | BEARING STRUCTURE - A bearing structure includes a housing having a bore that penetrates the housing, a rotation shaft inserted into the bore, an annular first metal bearing and an annular second metal bearing, which are provided apart from each other in an axial direction in the bore and rotatably support the rotation shaft, and a ventilation passage provided in the housing. The ventilation passage is formed on the housing-side contact surfaces which are formed on an inner surface of the housing, and bypasses at least one of the first metal bearing and the second metal bearing. Through ventilation passage, a closed area sandwiched between the both first metal bearing and second metal bearing inside the bore communicates with an outside area. | 08-20-2009 |
20110142386 | BEARING RING AND METHOD FOR COOLING A BEARING RING - The present invention relates to a bearing race, which exhibits an inside facing a rotational bearing-race axis and an outside facing away from the rotational bearing-race axis, in which at least one cooling-medium channel is disposed at the outside of the bearing race, which exhibits a hydraulic diameter of at least 1 millimeter and a length of at least two spiral turns. | 06-16-2011 |
20130004105 | BEARING ASSEMBLY - A bearing assembly includes a tubular outer housing and a tubular inner mandrel. The outer housing has an exterior surface and an interior surface defining an interior bore. The inner mandrel has an exterior surface and an interior surface defining an interior mud flow channel. The inner mandrel is journaled for rotation within the interior bore of the outer housing. Pairs of diamond bearings having opposed curved bearing surfaces are disposed between the outer housing and the inner mandrel. One of each pair of opposed curved bearing surfaces being convex and being secured to one of the inner mandrel or outer housing and another of each pair of opposed curved bearing surfaces being concave and secured to another of the inner mandrel or outer housing. The opposed curved bearing surfaces accommodate limited relative misalignment and provide radial and axial support between the inner mandrel and the outer housing | 01-03-2013 |
