Abstract

The present disclosure relates to various apparatus for controllably restricting an air flow to a vacuum controlled actuator in a vehicle induction system for the purpose of controlling a response of the actuator. In one embodiment the apparatus is a hose component having a hose that forms a flow channel, and which has an air flow restrictor seated within the flow channel. The air flow restrictor has a main body portion and an end wall having a reduced diameter air flow aperture. The air flow restrictor restricts air flow through the hose by a predetermined degree to tailor a response of the actuator in flow communication with the hose.

First claim

What is claimed is:

1. A pressure or vacuum controlled actuator for operating a valve associated with one cylinder bank of a vehicle engine, comprising:
an actuator cover forming a portion of and enclosing a portion of a pressure/vacuum chamber arranged in an interior of the pressure or vacuum controlled actuator;
an inlet port member formed directly on and formed in one piece together with the actuator cover, the inlet port member having
a first end arranged in the pressure/vacuum chamber at an interior of the actuator cover;
a second end arranged at an exterior of the pressure or vacuum controlled actuator; and
an inlet passage extending from the first end to the second end of the inlet port member, the inlet passage conducting pressure or vacuum through the actuator cover into the pressure/vacuum chamber to operate the actuator, the inlet passage of the inlet port member having an inside diameter;

a response tailoring air flow restrictor having an outside diameter smaller than the inside diameter of the inlet passage of the inlet port member, the air flow restrictor sized to be insertable into an interior of the inlet passage, the air flow restrictor having a reduced diameter aperture of a predetermined cross-sectional area, the predetermined cross-sectional area sized to restrict flow in the inlet port member to tailor the response of the actuator;
wherein the air flow restrictor, after insertion, is secured into the interior of the inlet passage by an adhesive;
wherein the reduced diameter aperture of the separate response tailoring air flow restrictor is sized to tailor a response of the actuator to a pressure or vacuum applied at the inlet port member, such that the pressure or vacuum controlled actuator is configured to position and move in unison with other pressure or vacuum controlled actuators of the vehicle engine.

2. The pressure or vacuum controlled actuator according to claim 1 , wherein
the actuator cover, and the inlet port member are unitary, formed together with in one piece from a plastic material.

3. An air induction system for a motor vehicle comprising:
a first pressure or vacuum controlled actuator for operating a valve associated with a first cylinder bank of a vehicle engine, comprising:
a first actuator cover forming a portion of and enclosing a portion of a first pressure/vacuum chamber arranged in an interior of the pressure or vacuum controlled actuator;
a first inlet port member formed directly on and formed in one piece together with the first actuator cover, the first inlet port member having
a first end arranged in the first pressure/vacuum chamber at an interior of the first actuator cover;
a second end arranged on an exterior of the first actuator cover of the first pressure or vacuum controlled actuator; and
a first inlet passage extending from the first end to the second end of the first inlet port member, the first inlet passage conducting pressure or vacuum through the first actuator cover into the first pressure/vacuum chamber to operate the first pressure or vacuum controlled actuator;

a first response tailoring air flow restrictor is a separate component, having an outside diameter smaller than an inside diameter of the first inlet passage of the first inlet port member, the first response tailoring air flow restrictor sized to be insertable into an interior of the first inlet passage, the first response tailoring air flow restrictor having a reduced diameter aperture of a predetermined cross-sectional area, the predetermined cross-sectional area sized to restrict flow in the first inlet port member to tailor the response of the first actuator;
wherein the first response tailoring air flow restrictor, after insertion, is secured into the interior of the first inlet passage by an adhesive;
a second pressure or vacuum controlled actuator for operating a second valve associated with a second cylinder bank of the vehicle engine, comprising:
a second actuator cover forming a portion of and enclosing a portion of a second pressure/vacuum chamber arranged in an interior of the second pressure or vacuum controlled actuator;
a second inlet port member formed directly on and formed in one piece together with the second actuator cover, the second inlet port member having
a first end arranged in the second pressure/vacuum chamber at an interior of the second actuator cover;
a second end arranged on an exterior of the second actuator cover of the second pressure or vacuum controlled actuator;
a second inlet passage extending from the first end to the second end of the second inlet port member, the second inlet passage conducting pressure or vacuum through the second actuator cover into the second pressure/vacuum chamber to operate the second pressure or vacuum controlled actuator;

wherein a single pressure/vacuum source signal is supplied to the inlet port members of both first pressure or vacuum controlled actuators together,
wherein the reduced diameter aperture of the first response tailoring air flow restrictor is sized to tailor a response of the first actuator to the single pressure or vacuum signal applied at both the first and second inlet port members, to coordinate and synchronize movement and modulation of the first and second pressure or vacuum controlled actuators to act together in unison.

4. The air induction system according to claim 3 , wherein the first actuator cover, and the first inlet port member are unitary, formed together with in one piece from a plastic material.

5. The air induction system according to claim 3 , wherein
the second inlet port member includes
a second response tailoring air flow restrictor having an outside diameter smaller than an inside diameter of the second inlet passage of the second inlet port member, the second air flow restrictor sized to be insertable into an interior of the second inlet passage, the second response tailoring air flow restrictor having a reduced diameter aperture of a predetermined cross-sectional area, the predetermined cross-sectional area sized to restrict flow in the second inlet port member to tailor the response of the second actuator;
wherein the second response tailoring air flow restrictor, after insertion, is secured into the interior of the second inlet passage by an adhesive;
wherein the reduced diameter aperture of the second response tailoring air flow restrictor is sized to tailor a response of the second actuator to a pressure or vacuum applied at the second inlet port member.

6. The pressure or vacuum controlled actuator according to claim 5 , wherein
the diameters of the reduced diameter apertures of the first and second pressure or vacuum controlled actuators are sized to coordinate and synchronize movement and modulation of the pressure or vacuum controlled actuators such that the first and second pressure or vacuum controlled actuators are tailored to move and position together in unison.
