发明名称 ELECTRONIC THROTTLE BODY ASSEMBLY
摘要 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.

主权项 1. An valve assembly comprising: a housing defining a throttle bore; a throttle plate disposed in the bore and mounted on a shaft; an electric motor having a pinion gear; a gear assembly being constructed and arranged to transfer rotational drive from the electric motor to the throttle plate; and biasing structure constructed and arranged to bias the gear assembly and thus the shaft to cause the throttle plate to close the throttle bore defining a closed position thereof, wherein, when the motor is energized, rotation of the gear assembly, against the bias thereon, causes rotation of the shaft to move the throttle plate from the closed position to an open position.
