Patent number: 10138820Abstract: An excentric pin for an electronic throttle control assembly, which is used to adjust the default position of at least one spring used to control the position of a valve plate, where the valve plate is located in an opening of a housing in the electronic control assembly. The excentric pin is used to adjust the default angle of the valve plate to have an angular tolerance of +/?0.10°. The excentric pin is slideably pressed into an aperture of the housing of the electronic throttle control assembly, and turned using some type of driver. The electronic throttle control assembly may be a one-spring design, or a two-spring design, where the two-spring design requires only one spring pin and the excentric pin. Also, the excenter pin may be used to adjust the position of the sector gear, e.g., function as the lower mechanical stop to provide a minimum opening angle for low leakage, and a minimum opening angle to avoid throttle plate corking into opening of the housing.Type: GrantFiled: October 25, 2016Date of Patent: November 27, 2018Assignee: Continental Automotive Systems, Inc.Inventors: Stefan Köhler, Stefan Burkhard, John Norman Stockbridge

Patent number: 9657650Abstract: 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.Type: GrantFiled: May 19, 2015Date of Patent: May 23, 2017Assignee: Continental Automotive Systems, Inc.Inventors: Mohammed Rizwan Khan, Donald Taylor, John Norman Stockbridge, Stefan Köhler, Nathan Cowan, Joy Jacobs, Jennifer Betsistas, Dominik Ilse

Patent number: 9115677Abstract: A vacuum assist system attaches to an intake line and an intake manifold of an internal combustion engine having a throttle. The vacuum assist system includes a venturi valve, a reservoir, and a proportionally controlled valve. The proportionally controlled valve is movable between an open position and a closed position. The proportionally controlled valve moved to the open position when the throttle is in the partially open position such that air is flows from the inlet to the intake manifold, from the inlet to the venturi valve, from the venturi valve to the intake manifold, and from the reservoir to the venturi valve. The proportionally controlled valve moves to the closed position when the throttle is in the almost-closed position such that air flows from the inlet to the intake manifold via the intake line and from the reservoir to the intake manifold to reduce the pressure within the reservoir.Type: GrantFiled: October 29, 2013Date of Patent: August 25, 2015Assignee: GM Global Technology Operations LLCInventors: John Norman Stockbridge, Matthew W.

Patent number: 8720414Abstract: 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.Type: GrantFiled: December 22, 2011Date of Patent: May 13, 2014Assignee: Continental Automotive Systems, Inc.Inventors: Nathan Cowan, John Norman Stockbridge
