Abstract: A vehicle cleaning system that can be manufactured to integrate with an existing motor vehicle or as part of a new vehicle manufacture, providing a convenient automated method of cleaning a large motor vehicle such as a trailer or RV. The vehicle cleaning system can be implemented by delivering water from either an independent valve running to an onboard cleaning system; a water line connection; or from an onboard holding tank which may contain water or other cleaning agents, to a valve system operating a series of extrusion nozzles. The cleaning system may have one or more manual or electromechanical pumps and a manual or electromechanical valve system to actuate at least one cleaning cycle, or to activate the operation of the vehicle cleaning system in specific zones along the body of a vehicle. The vehicle cleaning system may operate by means of a roof-mounted actuated piping and nozzle system or an extrusion nozzle spray system having recessed extendable nozzles, or an integrated nozzle system.

Abstract: A fluid pump apparatus for an artificial lift system has a barrel, a standing valve positioned at a lower end of the barrel so as to be movable between an open position and a closed position, a plunger reciprocatingly mounted in the barrel, a traveling valve positioned in an interior of the plunger so as to control fluid flow through the plunger, and a pilot slidably positioned in the plunger. The plunger has a first aperture at an upper portion thereof and a second aperture extending through a wall of the plunger so as to open to a channel extending through the channel. The traveling valve is slidably movable within an interior of the plunger. The plunger has a seat that is cooperative with a surface of the traveling valve. The pilot is cooperative at the surface of the traveling valve so as to move the traveling valve.

Abstract: A deliquification pump for deliquifying a well comprises a fluid end pump adapted to pump a fluid from a wellbore. In addition, the deliquification pump comprises a hydraulic pump adapted to drive the fluid end pump. The hydraulic pump includes a first internal pump chamber and a first pump assembly disposed in the first chamber. The first pump assembly includes a piston having a first end, a second end, and a throughbore extending between the first end and the second end. In addition, the first pump assembly includes a first wobble plate including a planar end face axially adjacent the second end of the piston and a slot extending axially through the first wobble plate. The first wobble plate is adapted to rotate about the central axis relative to the housing to axially reciprocate the piston and cyclically place the throughbore of the piston in fluid communication with the slot.
