Abstract
An ejector is provided for an induction system in a vibratory system generating vibration, including a dust ejector for an air induction system of an internal combustion engine. An ejection valve is provided by an inertial mass inertially activated and driven by the vibration to discharge contaminant from the induction system.
Claims17
An ejector for an induction system in a vibratory system generating vibration, comprising an ejection valve comprising an inertial mass inertially activated and driven by said vibration to discharge contaminant from said induction system, wherein said inertial mass is a plunger inertially driven by said vibration to vibrate and oscillate to an amplitude along an axial oscillation axis, said plunger oscillates along an axial travel stroke in a channel extending along said oscillation axis, said plunger having first and second axially spaced valve faces, said channel having first and second axially spaced valve seats engaged by said first and second valve faces, respectively.
An ejector for an induction system in a vibratory system generating vibration, comprising an ejection valve comprising an inertial mass inertially activated and driven by said vibration to discharge contaminant from said induction system, said inertial mass being a plunger inertially driven by said vibration to vibrate and oscillate to an amplitude along an axial oscillation axis, said plunger translating and oscillating along an axial travel stroke in a channel extending along said oscillation axis, said plunger having at least one valve face, said channel having at least one valve seat engaged by said valve face at one end of said travel stroke, said plunger having an axially facing impactor surface separate from said valve face, said channel having an impaction anvil surface separate from said valve seat and axially facing said impactor surface and impacted thereby during oscillation of said plunger along said axial travel stroke along said oscillation axis, said impactor surface repeatedly striking said anvil surface to provide a hammer-effect, fostering vibratory feeder movement of said contaminant through said channel.
A method for ejecting contaminant from an induction system in a vibratory system generating vibration, comprising providing an ejection valve comprising an inertial mass, and inertially activating and driving said inertial mass by said vibration to discharge contaminant from said induction system, and comprising providing said inertial mass as a plunger, and inertially driving said plunger by said vibration to vibrate and oscillate to an amplitude along an axial oscillation axis, and translating and oscillating said plunger along an axial travel stroke in a channel extending along said oscillation axis, providing said plunger with at least one valve face providing said channel with at least one valve seat, and engaging said valve face and said valve seat at one end of said travel stroke,
- and comprising:
- providing said plunger with first and second axially spaced said valve faces;
- providing said channel with first and second axially spaced said valve seats;
- alternately engaging said first and second valve faces with their respective said valve seat at distally opposite first and second ends of said travel stroke, to provide first and second alternately actuated shut-off valves, respectively;
- inertially actuating and translating said plunger to said first end of said travel stroke to engage said first valve face with said first valve seat and close said first shut-off valve, and disengaging said second valve face from said second valve seat to open said second shut-off valve;
- inertially actuating and translating said plunger to said second end of said travel stroke to disengage said first valve face from said first valve seat and open said first shut-off valve, and to engage said second valve face with said second valve seat to close said second shut-off valve.
A method for ejecting contaminant from an induction s stem in a vibrato system generating vibration comprising providing an ejection valve comprising an inertial mass, and inertially activating and driving said inertial mass by said vibration to discharge contaminant from said induction system, and comprising providing said inertial mass as a plunger, and inertially driving said plunger by said vibration to vibrate and oscillate to an amplitude along an axial oscillation axis, and translating and oscillating said plunger along an axial travel stroke in a channel extending along said oscillation axis, providing said plunger with at least one valve face providing said channel with at least one valve seat, and engaging said valve face and said valve seat at one end of said travel stroke,
- and comprising:
- providing said plunger with an axially facing impactor surface separate from said valve face;
- providing said channel with an impaction anvil surface separate from said valve seat and axially facing said impactor surface;
- impacting said anvil surface with said impactor surface during oscillation of said plunger along said axial travel stroke along said oscillation axis and repetitively striking said anvil surface with said impactor surface to provide a hammer-effect, fostering vibratory feeder movement of said contaminant through said channel.
