Patent number: 9358878Abstract: A fluid energy reducing device includes a body having multiple, oppositely directed flow restrictors extending away from opposite sides of the body. Each flow restrictor can have a geometric shape such as a pyramid, triangle, or a conical shape. Fluid such as a fuel traveling in a wave entering the flow restrictors accelerates as the flow area in a flow passage of the flow restrictors decreases. The work performed by accelerating the fluid flow through one or more apertures created in each flow restrictor reduces the energy of the wave, thereby reducing noise in the fluid tank having the fluid energy reducing device when the reduced size and velocity wave subsequently strikes tank structure or walls.Type: GrantFiled: June 19, 2012Date of Patent: June 7, 2016Assignee: TransNav Inc.Inventors: Steven Gerrit Vreeken, Timothy James Nixon

Patent number: 7182322Abstract: An insert disposed between two cooperating leaf springs. The insert includes a body including a stem having a plurality of radially extending ribs inserted into an aperture in a first leaf spring. The body includes a face which slidably engages a second leaf spring. The face includes a plurality of circular protrusions extending therefrom. A pin is inserted into a central bore formed by cooperating fingers that form the body, causing an outwardly extending radial retention force to be exerted onto the surface of the aperture in the first leaf spring.Type: GrantFiled: January 14, 2003Date of Patent: February 27, 2007Assignee: TransNav, Inc.Inventors: Percy P. Vreeken, Philip W. Gilbert

Patent number: 5857503Abstract: A fluid channeling device to facilitate the draining of fluid from a fluid reservoir in a motor vehicle. The device may be attached to the vehicle so that it remains generally fixed, or the device may be temporarily attached to the vehicle for use while changing the fluid in the vehicle. The device is generally positioned below or in proximity to where the drained fluid will originate so that the device collects and channels fluid flowing from the point of origin. The device also includes an elongated throat section so that a hose may be attached to the device to further facilitate channeling the drained fluid.Type: GrantFiled: November 8, 1996Date of Patent: January 12, 1999Assignee: Transnav, Inc.Inventor: Percy P. Vreeken

Patent number: 5829317Abstract: A unitary brake pedal spacer for use in a brake pedal assembly. The brake pedal assembly includes a brake pedal having a tubular section which is attached between two opposing side walls of a brake pedal bracket. The brake pedal spacer is inserted within the interior of the tubular section, and the tubular section is then inserted between a pair of opposing apertures formed in the sidewalls of the brake pedal bracket. A shoulder bolt is inserted through the brake pedal spacer and a nut is threaded onto an end of the shoulder bolt to secure the assembly. The brake pedal spacer is a unitary apparatus which provides both spacer and bushing functionality for the assembly.Type: GrantFiled: January 7, 1997Date of Patent: November 3, 1998Assignee: TransNav, Inc.Inventors: Percy P. Vreeken, Timothy J. Nixon, Michael A. Barnes
