| 241 | DUAL MECHANICAL SEAL WITH EMBEDDED BEARING FOR VOLATILE FLUIDS | US14105850 | 2013-12-13 | US20150167671A1 | 2015-06-18 | Joseph Jablonski; Colette Doll Greene |
| A fluid pump configured to prevent contact between volatile fluids and a ball bearing of the pump while providing the ball bearing with adequate lubrication. The fluid pump includes a pump casing having a fluid inlet and a fluid outlet, and a rotor set disposed within the pump casing for conveying fluid from the fluid inlet to the fluid outlet. The fluid pump further includes a recirculation chamber located adjacent the fluid outlet for collecting leaked fluid. The leaked fluid may be conveyed from the recirculation chamber back to the fluid inlet due to a pressure differential therebetween. The fluid pump may further include first and second seals that surround a drive shaft of the rotor, the first and second fluid seals defining a lubricant compartment therebetween that houses a ball bearing of the pump and that is filled with a continuously circulated, nonvolatile lubricant. | ||||||
| 242 | Scroll Pump Having Axially Compliant Spring Element | US14272389 | 2014-05-07 | US20150159653A1 | 2015-06-11 | Ronald J. Forni |
| A scroll pump includes a frame, a stationary plate scroll, an orbiting plate scroll, a tip seal(s), an eccentric drive mechanism which drives the orbiting plate scroll, and an axial compliance system. The eccentric drive mechanism includes a crankshaft, and bearings and a counterbalance disposed on the crankshaft. The counterbalance is mounted so as to be slidable along the crankshaft in the axial direction of the crankshaft. The axial compliance system includes a flexure and one set of springs for pre-loading the bearings. The flexure is interposed between one of the bearings and the counterbalance. The flexure allows the orbiting plate scroll to move away from the stationary plate scroll in the case of an assembly process which would otherwise result in the tip seal(s) being too forcefully engaged with the plate of the opposing plate scroll. | ||||||

| A diameter of a main bearing member 12m is defined as Dm, a length thereof is defined as Lm, a diameter of the eccentric bearing member 11e is defined as De and a length thereof is defined as Le. A ratio (=Lm/Dm) of the length and the diameter of the main bearing member 12m and a ratio (=Le/De) of the length and the diameter of the eccentric bearing member 11e are set to Le/De≦Lm/Dm≦1. Therefore, contact at edge portions of both ends of the eccentric bearing member 11e does not occur, and it is possible to prevent contact at edge portions of both ends of the main bearing member 12m even if the main shaft 13m inclines, and to reduce a viscosity loss caused by oil 9a. Hence, the present invention provides a scroll compressor securing reliability of the bearing members 12m, 11e and 16s and having high efficiency. | ||||||

| 247 | FUEL CELL SYSTEM INCLUDING DIAGNOSTIC TECHNIQUE FOR UNBALANCED COMPRESSOR | US14269922 | 2014-05-05 | US20140242491A1 | 2014-08-28 | Oliver Maier; Bernd Peter Elgas; Ulrich Dumke; Peter Willimowski |
| A diagnostic system for determining whether a rotor shaft of a compressor is unbalanced. The compressor includes a displacement sensor that measures the displacement of the rotor shaft as it is rotating. The sensor dynamic frequency signal is sent to a bandpass filter that filters out an eigen-frequency frequency that is a function of shaft elasticity and rotor dynamics. The filtered frequency signal is then rectified by a rectifier to make the filtered frequency signal positive. The rectified signal is then passed through a low pass filter that converts the rectified signal to a DC signal. The DC signal is then sent to a controller that determines if the amplitude of the signal is above a predetermined threshold, which indicates a problem with the balance of the compressor. | ||||||

| 259 | Shaft Bearings, Compressor with Same, and Methods | US12409091 | 2009-03-23 | US20100239447A1 | 2010-09-23 | James W. Bush |
| A bearing material composition that lines a support includes a combination of a thermoplastic conforming material and abrasive particles which provide a combined effect for remedying the effects due to edge loading that may be caused by misalignment between the bearing and a shaft to which a portion is rotatably mounted. The conforming material may be PTFE such that it does not have a memory and is subject to cold flow and creep. As a result, misalignment problems and edge loading are remedied by the combination of abrasive removal of metal material from the drive shaft at the location of edge loading and creep of the conforming material at the location of edge loading which may provide an overall greater bearing interface surface. | ||||||
