Title: Fuel pumping system and method

Abstract

A fuel pumping system that includes a pump drive is provided. A first pumping element is operatively connected to the pump drive and is operable to generate a first flow of pressurized fuel. A second pumping element is operatively connected to the pump drive and is operable to generate a second flow of pressurized fuel. A first solenoid is operatively connected to the first pumping element and is operable to vary at least one of a fuel pressure and a fuel flow rate of the first flow of pressurized fuel. A second solenoid is operatively connected to the second pumping element and is operable to vary at least one of a fuel pressure and a fuel flow rate of the second flow of pressurized fuel.

  • This patent describes a marine propulsion system. It comprises: an outboard two cycle internal combustion engine, a fuel tank, an oil tank, an oil-fuel mixer having a fuel inlet receiving fuel from the fuel tank, an oil inlet receiving oil from the oil tank, and an oil-fuel outlet delivering an oil-fuel mixture to the engine, a vapor separator coupled to the mixer and removing fuel vapor from the fuel. The vapor separator is connected between the fuel tank and the mixer.
  • This patent describes a valve operation control system in an internal combustion engine. It comprises: an engine valve openably and closably disposed between the atmosphere and at least two combustion chambers, at least one intake valve disposed between each combustion chamber and the induction manifold, at least one of the valves beginning to open to start an induction process when the angular position of the crankshaft is at an opening angular position for the valve and the induction process being ended when the crankshaft is at a closing angular position and the last one of the intake valves closes, andmore » a variable valve timing system for changing the timing of the induction process via control of at least one of the valves in compliance with predetermined operating conditions of the engine, the variable valve timing system including a camshaft having at least one splittable cam member with camlobe members for actuating the at least one intake valve.« less
  • This patent describes improvement in a low pressure drop valve connectible to a source of pressurized hydraulic fluid for modulating hydraulic fluid flow. The improvement includes valve body means defining an axially extending tapered bore and having hydraulic flow inlet and outlet ports, a plug valve movable axially in that bore and having an externally tapered surface facing the tapered bore and movable axially relative thereto the increase or decrease a gap formed between the tapered surface and the tapered bore, for controlling the flow of hydraulic fluid via the gap and at least one of the ports, means responsivemore » to a side stream of pressurized hydraulic fluid to control axial movement of the plug valve in the tapered bore, the means including first and second pistons connected with the plug valve to move axially therewith, the valve body means forming first and second cylinders respectively receiving the pistons for application of hydraulic fluid pressure to the pistons for displacing the pistons and plug valve axially, and protective O-rings.« less
  • This patent describes a high speed rotary liquid pump, adapted to be driven by a shaft in the core of a gas turbine engine. It comprises a rotatable impeller having a plurality of straight blades extending radially from an annular hub, the hub having a central aperture of sufficient size to engage the shaft for rotation therewith; a pump housing surrounding the impeller and defining a generally annular pump cavity for receiving the rotatable impeller; the housing also defining an annular fluid inlet aperture leading axially into the cavity adjacent the hub, a shield member axially adjacent the aperture andmore » disposed between fluid entering the aperture and the shaft, whereby circumferential swirl of the fluid due to contact with the shaft is minimized, and at least one fluid outlet passage extending tangentially from the periphery of the cavity adjacent the tips of the blades.« less
