Patents by Inventor Ranny Joe Nunley

Ranny Joe Nunley 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).

  • High pressure dual-action hydraulic pump
    Patent number: 8061179
    Abstract: A high pressure pump includes a pump housing. A piston rod located within the pump housing defines a plurality of pump cavities and a plurality of piston cavities. Movement of the piston within the piston cylinder pumps the fluid from the piston cavities out of the high pressure pump. The continuous pumping of HWBF from the pump housing provides fluid at a relatively constant flow and pressure. The HWBF pressure is also at a higher pressure than traditional single stage high pressure pumps can provide.
    Type: Grant
    Filed: August 12, 2008
    Date of Patent: November 22, 2011
    Assignee: GM Global Technology Operations LLC

  • Gravity fill system with pressure check valve
    Patent number: 7937979
    Abstract: A hydroform die includes a plurality of seal units to provide fluid to die cavities. The plurality of seal units each define a piston cylinder. A piston is located within the cylinder and is selectively moveable between an open and a closed position. Additionally, the piston at least partially defines a valve chamber located on a first side of the piston and a piston chamber located on a second side of the piston. A piston fluid passage is defined by the piston to fluidly connect the valve chamber and the piston chamber.
