Patent number: 8011347Abstract: An exhaust brake has a body with a passageway for exhaust gases therein. A valve member is movably located within the passageway for selective movement between an open position where the valve member opens the passageway and exhaust gases are free to move through the passageway and a closed position where the valve member blocks the passageway and the passage of exhaust gases through the passageway. The valve member has an aperture therethrough to permit a limited flow of exhaust gases through the aperture when the aperture is open. An exhaust valve actuator mechanism is coupled to the valve member for moving the valve member between the open position and the closed position. A closure member is positioned adjacent to the aperture.Type: GrantFiled: August 2, 2010Date of Patent: September 6, 2011Assignee: Jenara Enterprises, Ltd.Inventors: Andre F. Lhote, Vincent A. Meneely, Gabriel Gavril, Tamara Spence, John P. Hartley

Publication number: 20110095221Abstract: An exhaust gas flow control valve assembly comprises a valve casing forming an exhaust gas passage defining a cylindrical inner peripheral surface and a butterfly-type exhaust gas flow control valve disposed within the exhaust gas passage and movable between an open position and a closed position. The flow control valve includes a single-piece valve disc member having a circumferential groove formed in an outer peripheral surface thereof, and a flat, resilient stainless steel sealing ring disposed in the groove with a clearance for radial displacement of the sealing ring relative to the groove. The sealing ring includes a cylindrical outer peripheral surface provided with rounded corners. The outer peripheral surface of the sealing ring is in firm contact with the inner peripheral surface of the valve casing solely by an elastic force of the sealing ring when the exhaust gas flow control valve is in the closed position.Type: ApplicationFiled: October 26, 2010Publication date: April 28, 2011Inventor: Gabriel GAVRIL

Patent number: 7913810Abstract: A high-performance muffler assembly for exhaust system of an internal combustion engine. The muffler assembly comprises an elongated casing having an inlet port and an exit port, a first pipe disposed within the casing and having an inlet end in fluid communication with the inlet port and an outlet end selectively fluidly connected to the exit port of the casing, and a first valve mounted within the casing. The first valve is selectively movable between a closed position and an open position for regulating an exhaust gas flow through the first pipe. The muffler assembly is operable in a number of different modes of operation including a high-performance mode, an exhaust braking mode, a reverse-flow mode, etc., determined by the positions of the first valve of the muffler assembly.Type: GrantFiled: March 8, 2010Date of Patent: March 29, 2011Assignee: Pacbrake CompanyInventors: Vincent A. Meneely, Brad Sebring, Gabriel Gavril

Patent number: 7527482Abstract: A method is provided for compressing a gas in a single cycle and in a single cylinder to a pressure of at least 17.2 Mpa with a compression ratio of at least about five to one. The method further comprises dissipating heat from the cylinder during the compression stroke whereby the gas is discharged with a temperature significantly less than isentropic. The apparatus comprises a hollow cylinder and a reciprocable free-floating piston disposed therein. The piston divides the cylinder into: (a) a compression chamber within which a gas can be introduced, compressed, and discharged; and, (b) a drive chamber, into which a hydraulic fluid can be introduced and removed for actuating the piston. The apparatus further comprises a piston stroke length to piston diameter ratio of at least seven to one. For operating the apparatus with a compression ratio of at least five to one, an outlet pressure of at least 17.Type: GrantFiled: March 26, 2003Date of Patent: May 5, 2009Assignee: Westport Power Inc.Inventors: Mihai Ursan, Anker Gram, Gabriel Gavril, Shahin Hessami, Ian Lockley
