Patents by Inventor Gary E. Rhoads

Gary E. Rhoads has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4741298
    Abstract: A rollerized timing valve lifter for use in high performance engines. It has a press fit hydraulic mechanism utilizing an oil supply feed means from the roller body through and to the hydraulic mechanism. It has structure to maintain a self adjusting lifter to zero valve lash due to engine wear and heat expansion. It further includes a method of altering valve timing automatically through an oil restricted oil bleed passage way leading to the pressure chamber thereby allowing a leak down or delay of valve timing at low speeds. The passageway is narrow enough to become substantially inoperative at high engine speeds to thereby produce effective solid lifter action.

  • Patent number: 4694787
    Abstract: A automatic fluid distributing valve timing device in combination with an internal combustion engine of which is adjustable and variable, a device controlling opening and closing degrees of the valves in relationship to the crankshaft of a common reciprocating engine. This device controls the opening of a valve by a pressurized oil co-ordinating disk working in conjunction with a actuating piston attached to the cylinder head of a high performance engine, of which when fed by oil pressure, opens intake and exhaust valves by the alignment of two elements allowing oil to flow for a regulated time and of which is adjustable, adjusting valve duration, overlap and lift. This device eliminates multiple working parts of the engines valve train such as the conventional cam, lifters, push rods and rocker arms, eliminating a large percent of friction and horsepower loss. The novel invention has very few working parts compared to the above mentioned valve train, resulting in a large horsepower increase.

  • Patent number: 4656976
    Abstract: A new and useful rocker arm for an internal combustion engine and more particularly a hydraulic actuated rocker arm of which varies valve timing automatically. Improving low end horsepower by altering valve opening and closing points, while engine speeds increase, valve duration and overlap increases automatically for a large fuel flow improving top end horsepower. This novel device also improves fuel economy and helps eliminate smog pollutant emissions to a minimum.

  • Patent number: 4602597
    Abstract: The present invention relates to push rods for an internal combustion engine and more particulary to a hydraulic push rod. A new and useful hydraulic push rod of which varies valve timing automatically, improves low end horsepower by altering valve opening and closing degrees, or points of opening in relationship to the crankshaft. While engine rpms increase, valve duration and overlap also increase automatically for a large flow of fuel at higher engine rpms. This novel device also improves fuel economy and smog pollutant emissions.

  • Patent number: 4601268
    Abstract: A new and useful two-way valve with an adjustable aperture, to work in combination with a hydraulic valve lifter in a combustion engine, and particularly that of a high performance engine, preventing valve overlap and shortening cam duration at low operating speeds. The two-way valve having an adjustable aperture restricted oil bleed passage way, leading to the pressure chamber allowing the lifter to bleed down, whereby the engine runs and operates at its perfected capabilities at low and high speeds. The passage way being adjustable for many cam profile characteristics, adjusted narrow enough allowing it not to bleed at a higher revolution per minute, consequently causing lifter pump up to a fully solid condition at higher engine speeds, and substantially incorporate an effective solid lifter action, but without pumping beyond its predetermined point of stability eliminating valve float which causes engine misfire.
