ABSTRACT:
An improved pre-detent tactile feedback assembly for a fluid control valve is provided. The pre-detent tactile feedback assembly includes an elastic member seated within an annular groove formed in the bore of a plunger valve assembly. Preferably, this elastic member is a garter type spring. When the plunger is moved from an opened to a closed position, a portion of the plunger contacts the elastic member, urging the elastic member outwardly into the groove. The additional force required to urge the elastic member into the groove provides a "feel" force to the control lever. Preferably, the groove is positioned within the bore so that this "feel" force is sensed just prior to actuation of an associated detent assembly.
