An object is to provide a type of device capable of properly cooling a bearing of a throttle body even under a condition that the throttle body receives heat of high-temperature intake air or exhaust gas. In the present invention, an engine coolant passage that guides a coolant of an engine is provided integrally with a member fixing a bearing to be adjacent to a circumferential wall of the bearing of the member fixing the bearing, which supports a throttle shaft, and heat transferred from the bearing (or likely to be transferred to the bearing) via the member fixing the bearing is carried away to the outside of a throttle body by the engine coolant.

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.

In at least some implementations, a throttle body assembly includes a body that has multiple throttle bores, multiple throttle valve heads received one in each of the throttle bores, at least one throttle valve shaft to which the throttle valve heads are coupled, and at least one of a fuel metering valve and a vapor separator carried by the body.

A throttle control assembly which includes a housing, and an adapter and an anti-rotation feature integrally formed with the housing. A scallop is integrally formed as part of the housing and substantially surrounds the anti-rotation feature. A first tapered portion and a second tapered portion are both integrally formed with the adapter. A first groove and a rib portion are also integrally formed as part of the adapter. A plurality of outer scallops are also integrally formed as part of the adapter. The anti-rotation feature, the scallop, and each of the plurality of outer scallops are integrally formed with the housing. A portion of the plurality of outer scallops are formed as part of the second tapered portion, and a portion of the plurality of outer scallops are formed as part of the rib portion.

A turbine supercharger includes: a turbine; a turbine housing which houses the turbine; and a turbine bypass valve for controlling a flow rate of exhaust gas to be supplied to the turbine. The turbine housing includes, inside the turbine housing: a scroll flow passage for guiding the exhaust gas to the turbine; an outlet flow passage for discharging the exhaust gas supplied to the turbine to outside of the turbine housing; and a bypass flow passage bypassing the turbine and connecting the scroll flow passage and the outlet flow passage. The turbine bypass valve includes: a valve rod; a valve body having a flat plate shape and being configured to revolve about the valve rod; and a valve housing having a cylindrical shape and defining a part of the bypass flow passage inside the valve housing. The valve housing is fixed to an inner peripheral wall surface of the bypass flow passage, inside the turbine housing.

A throttle body fuel injection system including a throttle body with at least one air intake, a fuel injector coupled to the throttle body at a fuel port and an annular ring coupled to the cylindrical inner wall of the air intake. The annular ring includes a primary fuel discharge orifice adjacent to the fuel port and a plurality of secondary fuel discharge orifices arranged radially around the annular ring for spraying atomized fuel into the air intake.

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.

In at least some implementations, a charge forming device for a combustion engine includes a throttle body and a throttle valve. The throttle body has a throttle bore with an inlet through which air flows into the throttle bore and an outlet from which a fuel and air mixture exits the throttle bore. The throttle bore has a throat between the inlet and outlet and the throat has a reduced flow area compared to at least one of the inlet and outlet. The throttle valve has a valve head received within the throat of the throttle bore and movable relative to the throttle body between a first position and a second position wherein the flow area between the valve head and the throttle body is greater when the valve head is in the second position than in the first position.

An exhaust valve includes a body defining a passage section and extending along an extension axis from an upstream inlet able to be connected to an upstream pipe to a downstream outlet able to be connected to a downstream pipe. A flap is positioned in the body, across the passage section, and rotates around a rotation axis secant to the extension axis between a closed orientation where the flap closes the passage section and an open orientation where the flap frees the passage section. A transmission member is aligned along the rotation axis and is secured to the flap by a first end, and the second end of which is positioned outside the body. A rotating actuator drives the flap via the second end of the transmission member. A fastening element is used to fasten the actuator on the outside of the body (2). The valve further includes at least one fin positioned between the body and the actuator. Also, an exhaust line includes such a valve.

An exhaust gas flap includes a flap tube (12), a flap diaphragm (16), in an interior of the flap tube on a pivot shaft (14) rotatable about a pivot axis (A), a pivot drive (30) for the pivot shaft (14) and a coupling device (36) coupling the pivot shaft to a drive shaft (34). The coupling device includes a first coupling area (42) rotationally coupled, positive-lockingly meshed with the drive shaft and a second coupling area (44) rotationally coupled, positive-lockingly meshed with the pivot shaft. A biasing element (58) is supported in relation to the coupling device and in relation to one shaft of the drive shaft and the pivot shaft. The coupling device is axially prestressed, by the prestressing element, away from the one shaft along in the direction of the pivot axis and is prestressed about the pivot axis in relation to the one shaft.
