| 20110200474 | INTEGRATED PUMP FOR COMPRESSIBLE FLUIDS - A swash pump for compressible fluids uses sealing contacts made between the nutatable swash plate and the fixed cone plates to centre and locate the inner swash sphere which slides against two resiliently mounted ring seals only, minimising pump friction. A slanted end of a common drive shaft supporting and turned by the rotor of an integrated, variable speed motor causes nutation of the sphere. All bearings, especially axially slidable roller bearings inside the sphere, may settle in position with respect to the common shaft for least frictional loss. This pump is also adapted for pumping explosive gases. | 08-18-2011 |
| 20110162753 | VAPOR RECOVERY PUMP REGULATION OF PRESSURE TO MAINTAIN AIR TO LIQUID RATIO - A method of operating a vapor recovery system that recovers vapors expelled from a vehicle during refueling at a fuel dispensing point and returns the vapors to an underground storage tank through a vapor flow path that is in fluid communication with an air to liquid regulator valve and a vapor pump. The method includes dispensing fuel into the vehicle through the fuel dispensing point, regulating an amount of vapor that is recovered through the fuel dispensing point with the air to liquid regulator valve in proportion to the fuel dispensed into the vehicle, detecting a parameter of the vapor recovery system, and maintaining a substantially constant pressure level in a first portion of the vapor return path that is disposed between the vapor pump and the air to liquid regulator valve. | 07-07-2011 |
| 20100143173 | DUAL-PLATE SWASH PUMP - A swash-plate machine for pumping fluids uses dual swash plates in complementary or mirror-image orientation. The vibration that is generated as a reaction to forced nutatory motion imposed on a single swash plate is thereby largely cancelled. Rotated orientation of the divider plate position in one chamber with respect to the other (preferably 90 degrees difference) provides four outputs per revolution instead of the two available from both sides of a single swash plate. Improved bearings for the part-spherical swash plate base permits only oscillatory movement for that part and facilitate better sealing. | 06-10-2010 |
