DIGITAL LINEAR ACTUATOR LARGE PORT SIDE-GATED CONTROL VALVE FOR ELECTRONIC THROTTLE CONTROL
First Claim
1. An apparatus, comprising:
- a valve assembly, including;
an actuator;
a valve member moveable between an open position and a closed position, the valve member connected to the actuator; and
a housing having an inlet port and an outlet port;
wherein the actuator controls the movement of the valve portion between the open position and the closed position to control the flow of air between the inlet port and the outlet port.

Abstract
A digital linear actuator (DLA) large port throttle control valve manifold assembly which is suitable for use with various automotive engines. The sidegate capnut is sized such that the full amount of throttle body intake manifold air is controlled to the engine. Apertures are formed as part of the side gate capnut to minimize axial air loading on the capnut, providing a pressure balance. Providing a pressure balance also reduces the axial force required to position the capnut, which in turn reduces size of the actuator needed to position the capnut, thus reducing the overall size of the DLA. The positional control of the DLA along with the internal plenum port(s) window profile provides the desired air flow for each commanded position.

11. A valve assembly, comprising:
-
a housing; an inlet port formed as part of the housing; an outlet port formed as part of the housing such that the outlet port is selectively in fluid communication with the inlet port; an actuator connected to the housing; a valve member connected to and controlled by the actuator, the valve member located in the housing between the inlet port and the outlet port; a circumferential wall formed as part of the housing, the valve member in contact with the circumferential wall; and a plurality of internal ports formed as part of the circumferential wall; wherein the actuator moves the valve member between an open position, such that air passes from the inlet port, through the plurality of internal ports, and through the outlet port, and the actuator moves the valve member to a closed position, where the valve member obstructs the plurality of internal ports, preventing the flow of air from the inlet port to the outlet port. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A throttle control valve assembly, comprising:
-
a housing; an inlet port integrally formed as part of the housing; an outlet port integrally formed as part of the housing; an interior plenum cavity formed as part of the housing, the inlet port selectively in fluid communication with the interior plenum cavity; a valve member disposed in the interior plenum cavity; an actuator connected to the housing, the valve member controlled by the actuator; an exterior plenum cavity formed as part of the housing, the exterior plenum cavity in fluid communication with the outlet port, and the exterior plenum cavity selectively in fluid communication with the interior plenum cavity; a circumferential wall formed as part of the housing such that the circumferential wall separates the interior plenum cavity from the exterior plenum cavity, the valve member being in contact with the circumferential wall; and a plurality of internal ports integrally formed as part of the circumferential wall, the plurality of internal ports providing selective fluid communication between the outlet port and the interior plenum cavity, and between the interior plenum cavity and the exterior plenum cavity; wherein the actuator moves the valve member to selectively obstruct the plurality of internal ports to control the flow of air from the inlet port to the outlet port. - View Dependent Claims (19, 20, 21, 22, 23)
