ELECTRONIC CONTROL VALVE HAVING AN INTEGRAL NON-CONTACT NOISE MITIGATION DEVICE

摘要

An electronic control valve having a valve stationary portion defining a substantially central bore extending along an axis of the valve, and a valve train including a movable member of the valve. The valve train moveable member is disposed in the central bore, and the valve train is adapted for reciprocal movement along the axis. A mass is engaged is with the valve train and adapted for reciprocal movement along the axis. A biasing means is disposed between the valve train and the mass. Reciprocal movements of the mass along the axis induced by forces exerted along the axis by the valve train are transmitted through the biasing means, whereby reciprocal movement of the valve train along the axis is dynamically reduced by the mass.

1. An electronic control valve, comprising:
a valve stationary portion defining a substantially central bore extending along an axis of said valve; a valve train including a movable member of said valve, said valve train moveable member disposed in said central bore, said valve train adapted for reciprocal movement along said axis; a mass engaged with said valve train and adapted for reciprocal movement along said axis; and a biasing means disposed between said valve train and said mass, reciprocal movements of said mass along said axis induced by forces exerted along said axis by said valve train transmitted through said biasing means, whereby reciprocal movement of said valve train along said axis is dynamically reduced by said mass.
