| 417328000 | Spring or weight motor | 9 |
| 20110200463 | PUMP, PARTICULARLY HIGH-PRESSURE FUEL PUMP - The invention relates to a pump, particularly a high-pressure fuel pump, having a housing, a drive shaft that is rotationally driven and has at least one drive section, and at least one pump piston, which is guided in a cylinder bore of a housing part of the pump in a sealed manner and which is driven by the drive section of the drive shaft at least indirectly in a lifting motion. The at least one pump piston is acted on by a spring element at least indirectly toward the drive section of the drive shaft. The spring element is disposed on the side of the drive shaft opposite the pump piston, and via a coupling device extending past the drive shaft it engages at least indirectly on the pump piston. | 08-18-2011 |
| 20120230847 | VIBRATING ARMATURE PUMP - The invention relates to a vibrating armature pump having a pump housing, which comprises a cylinder for receiving a substantially linearly displaceable pump piston unit ( | 09-13-2012 |
| 20140241911 | LEAF SPRING AND COMPRESSOR WITH LEAF SPRING - The present invention relates to compressor leaf springs, in particular, linear compressor leaf springs; the leaf springs comprising at least one spacer ( | 08-28-2014 |
| 20150147198 | AIR MAINTENANCE TIRE ASSEMBLY - A pumping device is used with a pneumatic tire mounted on a tire rim to keep the pneumatic tire from becoming underinflated. The pumping device includes a housing attached to the tire rim, a dynamic mass mechanically confined to radial movement relative to the housing and the tire rim, an intake port for ambient to enter the housing, and an exhaust port for forcing air into a tire cavity of the pneumatic tire for restoring air loss from an inflation volume within the tire cavity. | 05-28-2015 |
| 20150147199 | AIR MAINTENANCE TIRE ASSEMBLY - A pumping device is used with a pneumatic tire mounted on a tire rim to keep the pneumatic tire from becoming underinflated. The pumping device includes a housing attached to the tire rim, a dynamic mass mechanically confined to linear movement relative to the housing and the tire rim, the dynamic mass moving in response to shock loads transferred from the tire rim to the dynamic mass and pumping ambient air into the housing, an intake port for ambient air to enter the housing, and an exhaust port for forcing pressurized air into a tire cavity of the pneumatic tire for restoring air loss from an inflation volume within the tire cavity. | 05-28-2015 |
| 20150147200 | AIR MAINTENANCE TIRE ASSEMBLY - A pumping device is used with a pneumatic tire mounted on a tire rim to keep the pneumatic tire from becoming underinflated. The pumping device includes a housing attached to the tire rim, a dynamic mass mechanically confined to rotational movement relative to the housing and the tire rim, the dynamic mass moving in response to a minimum angular velocity of the tire rim and pumping ambient air into the housing, an intake port for ambient air to enter the housing, and an exhaust port for forcing pressurized air into a tire cavity of the pneumatic tire for restoring air loss from an inflation volume within the tire cavity. | 05-28-2015 |
| 20150147201 | AIR MAINTENANCE TIRE ASSEMBLY - A pumping device is used with a pneumatic tire mounted on a tire rim to keep the pneumatic tire from becoming underinflated. The device includes a pumping device attached to the tire rim, a dynamic mass mechanically confined to rotational movement relative to the pumping device and the tire rim, the dynamic mass moving in response to a minimum angular acceleration and a minimum angular velocity of the tire rim and pumping ambient air into the pumping device, an intake port for ambient air to enter the pumping device, and an exhaust port for forcing pressurized air into a tire cavity of the pneumatic tire for restoring air loss from an inflation volume within the tire cavity, the dynamic mass and the pumping device both being weighted equally on each side of a centerline of the tire rim. | 05-28-2015 |
| 417329000 | Fluid weight (e.g., gravity vessel) | 2 |
| 20090016905 | Fluid Mechanical Converter - The invention relates to a fluid mechanical converter having at least one energy-accumulator mass system that can be powered by a power drive. To provide a fluid mechanical converter, which improves overall efficiency using the simplest components, it is proposed according to the invention that the displacement of the driven energy accumulator-mass system is overlaid with a displacement that is caused by at least one inertial force. | 01-15-2009 |
| 20110250081 | Top-mounted digital-control tower pumping unit - A top-mounted digital-control tower pumping unit includes a tower frame ( | 10-13-2011 |
