| 201 | Pump integrated with two independently driven prime movers | US14944368 | 2015-11-18 | US09920755B2 | 2018-03-20 | Thomas Afshari |
| A pump having at least two fluid drivers and a method of delivering fluid from an inlet of the pump to an outlet of the pump using the at least two fluid drivers. Each of the fluid drives includes a prime mover and a fluid displacement member. The prime mover drives the fluid displacement member to transfer fluid. The fluid drivers are independently operated. However, the fluid drivers are operated such that contact between the fluid drivers is synchronized. That is, operation of the fluid drivers is synchronized such that the fluid displacement member in each fluid driver makes contact with another fluid displacement member. The contact can include at least one contact point, contact line, or contact area. | ||||||

| 217 | Agitator tool for progressive cavity pump | US12272971 | 2008-11-18 | US08079753B2 | 2011-12-20 | John Sebree |
| The invention relates to an agitator tool for use with a progressive cavity pump for agitating a slurry of sand, heavy oil or water. The agitator tool has an elongate body having a lower end, an upper end, and a plurality of longitudinal grooves spaced between the lower and upper ends and radially about the body. The upper end is configured for coupling to a pump rotating element. Agitation members are pivotally mounted within the longitudinal grooves so as to be movable from an actuation position wherein the agitation members project outwardly from the body during rotation to agitate the slurry, to resting positions wherein the agitation members are folded within the grooves during installation or removal of the tool. | ||||||
| 218 | HIGH-PRESSURE FUEL PUMP | US13045669 | 2011-03-11 | US20110219947A1 | 2011-09-15 | Hans-Peter Deeg |
| A high-pressure fuel pump includes a housing and a swash plate which is mounted in the housing and is arranged in an oil space of the housing. A drive shaft is connected to the swash plate and passes through a housing opening, and with a seal for the drive shaft, which seal is mounted in the housing in the region of the housing opening. The high-pressure fuel pump has a plurality of pump elements for sucking up, compressing and ejecting fuel, which pump elements can be acted upon consecutively by the rotatable swash plate. In a pump of this type, the fuel pump has at least one magnet, the magnetic force field of which acts on the oil space of the housing. Premature wear of the pump, in particular premature wear of the seal, is avoided since the magnet separates off iron-containing dirt particles found in the oil. | ||||||
