Patent number: 9410469Abstract: A valve device for an internal combustion engine includes a housing with an inlet and an outlet, a passage opening which fluidically connects the inlet with the outlet, a first valve-closing member which controls the passage opening, an actuator, a valve rod on which the first valve-closing member is arranged, a stop element, a spring surrounding the valve rod, and an element. A first end of the spring is supported against the first valve-closing member, and a second end of the spring is supported against the stop element. The element substantially surrounds the spring. The element comprises a first lateral surface and a second lateral surface in mutual engagement with each other. The first lateral surface abuts against the first valve-closing member and is movable therewith. The second lateral surface abuts against the stop element. The first valve closing member moves relative to the stop element.Type: GrantFiled: April 27, 2012Date of Patent: August 9, 2016Assignee: PIERBURG GMBHInventors: Stefan Vitt, Osman Sari, Michael Wagner, Bernd Homeyer

Patent number: 9016265Abstract: An exhaust gas recirculation valve for an internal combustion engine includes a housing comprising an exhaust gas inlet and an exhaust gas outlet, and a valve closing body fastened to a valve rod. The valve rod is movable. A valve seat is arranged between the exhaust gas inlet and the exhaust gas outlet. A guide bushing comprising a first section guides the valve rod in the housing. A sealing ring is arranged at an end of the guide bushing remote from the valve closing body. The valve closing body is lowered onto the valve seat by a movement of the valve rod and lifted from the valve closing body by an opposite movement of the valve rod. A circumferential gap is formed between the valve rod and the guide bushing in the first section of the guide bushing directed toward the sealing ring.Type: GrantFiled: August 3, 2011Date of Patent: April 28, 2015Assignee: Pierburg GmbHInventors: Stefan Vitt, Osman Sari, Gérard Dietz

Patent number: 5701874Abstract: A control valve for the recycling of exhaust gas from an exhaust gas channel to an air inlet channel of the engine, wherein a valve member of the valve opens and closes a valve opening between the exhaust gas channel and the air inlet channel. An electromagnetic control unit acts on the valve member to open the valve and a spring biasses the valve to a closed state. The valve member has a closure portion for closing the valve and is formed with a balancing section spaced from the closure portion and formed with a cross-sectional area equal to that of the closure portion so that the air pressure in the inlet channel applies equal and opposite forces on the balancing section and the closure portion whereby the valve is balanced and not subject to pressure variations in the air inlet channel, such as due to turbocharging.Type: GrantFiled: April 17, 1996Date of Patent: December 30, 1997Assignee: Pierburg AGInventors: Osman Sari, Helmut Blank
