A valve assembly for an exhaust system of a vehicle comprises a housing defining an inlet, an outlet, and a longitudinally extending exhaust gas passageway in fluid communication with the inlet and the outlet. The valve assembly further comprises a valve flap disposed in the housing and rotatable between a first position restricting exhaust gas flow through the exhaust gas passageway, and a second position whereat exhaust gas flow through the exhaust gas passageway is less restricted. A mass damper is disposed within the exhaust gas passageway and attached to the valve flap. The mass damper includes end portions and an intermediate portion disposed between the end portions with the intermediate portion having a thickness that is greater than a thickness of the end portions. The mass damper is positioned proximate an inner surface of the housing and positioned between the valve flap and the housing when the valve flap is at the second position.

An electric actuator comprises a motor and a plate, wherein the motor has an electric contact in electrical contact with the plate. An intermediate shaft is in contact with the plate. A controller is fixed to an upper part of the actuator. The controller has an electrical output electrically communicating with the electric contact of the motor through the intermediate shaft and the plate.

A method to manufacture a throttle valve for an internal combustion engine comprising a valve body having a seat and a tube for the passage of conditioning fluid; an actuating device, which controls the rotation of a throttle plate; and a substantially uniform layer of a structural and heat-conducting resin interposed between the seat and the tube and applied on the entire available surface of the seat; the method comprising the steps of manufacturing the valve body provided with the seat by causing a first metal material to undergo a die casting process; applying a trace of the structural and thermosetting resin on the bottom of the seat; and inserting the tube into the seat so as to obtain a substantially uniform layer of the structural and thermosetting resin, which is interposed between the seat and the tube.

A valve device that includes a valve body; a valve shaft configured to rotate the valve body; a coil spring being electrically conductive and configured to be twisted with rotation of the valve body and the valve shaft; a first conductive member being electrically conductive and facing an inner circumferential surface or an outer circumferential surface of the coil spring in a radial direction of the coil spring; and a first detector configured to detect at least one of a rotation angle of the valve body or a rotation angle of the valve shaft based on an electrostatic capacitance between the coil spring and the first conductive member, the electrostatic capacitance changing according to a state of the coil spring that changes with the rotation of the valve body and the valve shaft.

A valve assembly for an exhaust system of a vehicle. The valve assembly includes a housing, a valve flap and a mass damper. The housing defines an inlet, an outlet, and a longitudinally extending exhaust gas passageway in fluid communication with the inlet and the outlet. The valve flap is disposed in the housing and is rotatable between a first position restricting exhaust gas flow through the exhaust gas passageway, and a second position whereat exhaust gas flow through the exhaust gas passageway is less restricted. The mass damper is disposed within the exhaust gas passageway. The mass damper is attached to the valve flap and comprise of a material having a high density. The mass damper is shielded from the exhaust gas flowing through the exhaust gas passageway when the valve flap is in the second position.

A throttle valve housing (1) for a throttle valve arrangement for an internal combustion engine, wherein the throttle valve housing (1) is used to accommodate a pivotally mounted throttle valve and provides movement space for the throttle valve, wherein the throttle valve housing (1) has an inflow opening (2) on a first side for receiving a fluid and the throttle valve housing (1) has an outflow opening (3) on a second side for discharging a fluid, and wherein at least one sealing piece (4) projecting into the flow cross-section is arranged in the movement space of the throttle valve housing (1) and is used as a stop for the throttle valve in the closed position. Improved sealing characteristics are achieved in that the sealing piece (4) is formed in the wall of the throttle valve housing (1) in a non-cutting manner.

Airtightness of a connector molding is improved. There is provided a connector molding in which a conductor and a fixing member are integrally molded with a molded body including a connector portion. The conductor is fixed to the fixing member, and is integrally molded with the molded body in a state in which an external connection end portion protrudes into a space within the connector portion. A part of the fixing member is exposed to the space within the connector portion and the remaining portion is covered by the molded body, or the entire fixing member is covered by the molded body.
