Abstract

Throttle valve has a flexible seating, a valve pin with 2 ends which each have a seating collar and a bushing. After assembly of the components, a pref. Araldite (RTM) type plastomer is cast in, and forms the valve body. Pref. two shells are fitted to the sides of the seating and the vol. for the body is bounded by a reserve place for the passage of mounting screws, also an upper air outlet, an air evacuation pipe, a loading channel and lower feed channel for therplastomer, which if necessary is injected using compressed air.
