Patents by Inventor Mark A. Reeves

Mark A. Reeves 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: 10960193
    Abstract: A tattoo needle has a paddle secured at a point adjacent the distal end of the needle and a swivel secured to the proximal end of the needle. A stationary eyelet is secured to end of the swivel opposite the needle. A sleeve slides over the barrel, which rotates. The barrel retains the paddle of the needle, thus restricting rotating motion of the needle when the barrel is rotated.

  • Patent number: 6874754
    Abstract: An exhaust gas recirculation valve having a reciprocating pintle shaft supported by a sleeve bushing and having a labyrinthine pathway between a valve operating chamber and a shaft/bushing interface to minimize intrusion of exhaust gases into the interface. The labyrinthine pathway is formed between fixed annular elements of the valve body and shaft bushing and a movable annular element of the valve head telescopically disposed between the fixed elements.

  • Publication number: 20040051067
    Abstract: In a solenoid-actuated pintle valve assembly, the solenoid assembly is shrouded by a manifold jacket connected via an opening to a source of air at a pressure higher than the working gas pressure within the valve chamber. During operation of the valve and solenoid assembly, a low mass flow of air is forced continuously throughout the solenoid assembly and exits through any leaks in the jacket and along the bushing bores into the valve chamber. Thus, the bushing bore and solenoid assembly are actively protected against entry of contaminants. Further, since it is no longer necessary to vent the valve to permit the escape of gases leaking along the bushing bores, contaminant-laden gases are kept from being exhausted into the engine compartment and from leaving a carbon track residue. The invention is especially useful for exhaust gas recirculation valves on internal combustion engines.

  • Patent number: 6247461
    Abstract: A relatively simple pressure balanced high flow exhaust gas recirculation (EGR) valve includes an actuator and a separately formed valve assembly retained to the actuator by a deformed lip. The valve body has dual seats controlled by axially spaced heads which are pressure balanced when closed and allow high gas flow when open. The valve body and the associated valve shaft, or portions thereof, are formed of materials having similar coefficients of thermal expansion so that the shaft and body experience similar thermal growth and good seating of the spaced valves is maintained regardless of gas temperature variations. Thickened portions at the valve seats comprise annular ends of a control portion which resist distortion of the seats. The valve body is configured for installation in a cylindrical bore or recess of an associated manifold or other gas passage defining member.
