The present invention is a throttle body assembly which is adaptable for both gasoline and diesel applications, and may also be used for applications to meter fluid, such as for a water cooling valve. The throttle body assembly includes at least one bearing assembly and at least one seal which is used to configure the bearing assembly to withstand a high-pressure environment.

Bearing seal assembly for electronic throttle control valve

A throttle body assembly includes a housing defining a throttle bore with a throttle plate in the bore and mounted on a shaft. An electric motor has a pinion gear. A gear assembly includes an intermediate gear and a sector gear and transfers rotational drive from the electric motor to the throttle plate. Biasing structure biases the sector gear and thus the shaft to cause the throttle plate to close the throttle bore defining a closed position thereof. When the motor is energized, rotation of the pinion gear causes rotation of the gear assembly, against the bias on the sector gear, thereby causing rotation of the shaft to move the throttle plate from the closed position to an open position. A position sensor assembly determines a position of the plate.

Electronic throttle body assembly

A throttle body assembly includes a housing defining a throttle bore with a throttle plate in the bore and mounted on a shaft. An electric motor has a pinion gear. A gear assembly transfers rotational drive from the electric motor to the throttle plate. Biasing structure biases the gear assembly and thus the shaft to cause the throttle plate to close the throttle bore defining a closed position thereof. When the motor is energized, rotation of the gear assembly, against the bias biasing structure, thereby causing rotation of the shaft to move the throttle plate from the closed position to an open position. A position sensor assembly determines a position of the plate.

Improved throttle body assemblies are described. More particularly, throttle body assemblies having improved throttle position sensor assemblies are described. In one aspect, a throttle body assembly for providing controlled aspiration to an engine is described. The assembly comprises a throttle body housing defining a throttle bore for receiving a throttle plate. The throttle plate is actuatable by an electric motor. The assembly further comprises a throttle position sensor configured to monitor positions of the throttle plate. The throttle assembly further comprises an electric discharge path formed between the throttle position sensor and the throttle body housing, wherein the electric discharge path substantially prevents the accumulation of residual electric charge across the throttle position sensor.

Throttle body assembly

Throttle body assemblies having improved throttle position sensing assemblies and a method of integrating a throttle position sensor assembly with a throttle body assembly are described. The method comprises the steps of: i) press-fitting a sensor element onto a shaft of a throttle plate of a throttle body assembly; ii) engaging one or more inwardly extending members of the sensor element with one or more recessed portions formed on the shaft of the throttle plate; and iii) disposing an inductive rotary position sensor proximate the sensor element, wherein the press-fit engagement and one or more inwardly extending members limit axial and rotational movement of the sensor element with respect to the throttle plate, and wherein the inductive rotary position sensor detects a relative position of the sensor element for the purpose of ascertaining a position of the throttle plate.

Throttle position sensor assembly

An electronic throttle control housing structure () for a vehicle includes an upper housing (), a lower housing () mating with the upper housing, and a sensor assembly () clamped between the upper housing and the lower housing. One of the upper housing or the lower housing has surfaces defining slot structure () therein. A portion of the sensor assembly is received in the slot structure in interference fit relation with the surfaces defining the slot structure. Thus, no screws or glue is needed to mount the sensor assembly in the housing structure.
