Publication number: 20120199246Abstract: The invention is based on the insight that a filling system obtained by combining a “Kruse” compatible threaded socket and an annular magnet as required for the operation of the “Elaflex” nozzle, will exhibit air exchange problems related to the difference in the positioning of the respective air intake openings of the “Kruse” bottle and the “Elaflex” nozzle. More particularly, the invention is based on the insight that by judiciously providing a chamber in fluid communication with the volume of air or vapor in the tank, filling may be made possible with a “Kruse” bottle as well as with an “Elaflex” nozzle.Type: ApplicationFiled: October 14, 2010Publication date: August 9, 2012Applicant: Inergy Automotive Systems Research (Societe Anonyme)Inventors: Laurent Budzyk, Paul Elong

Patent number: 8109739Abstract: A dosing pump for a liquid additive in fuel of a heavy fuel engine includes a piston, a cylinder, and a high resolution linear actuator, including a motor driven by a controller, for moving the piston axially in the cylinder. The pump includes a manifold, and a low friction dish-shaped seal having a peripheral portion forming a seal between the cylinder and the manifold in a fully extended position of the piston. The dish-shaped seal includes a top portion attached to the piston that moves with the piston such that the top portion of the seal is compressed against the manifold in the fully extended position. The shape of the seal minimizes non-linearity of the volume dosed as a function of movement of the piston, and the controller drives the motor so as to remove a remaining non-linearity of the volume dosed as a function of movement of the piston.Type: GrantFiled: September 3, 2004Date of Patent: February 7, 2012Assignee: Inergy Automotive Systems Research (Société Anonyme)Inventors: Nathan Wrench, Helen Victoria Lewis, Simon James Naylor, Charles Douglas Johnstone, James Beeching Neave
