Abstract: The present invention is related to a valve assembly and a method of manufacturing same. An extruded profile is used as a housing of the valve assembly, within said housing a single-component valve-element is injection-moulded, having a shaft-part and a plate-part, by moulding said single-component valve-element within a central bore against said housing during injection-moulding. Curing of the single-component valve-element and contracting thereof is allowed, providing for a clearance between the single-component valve-element and components of said housing for relative movement therebetween.

Abstract: In a throttle assembly for a flowing medium having an inlet and outlet and having two throttle devices disposed between them coaxially to one another, which each have at least one flow window for the passage of a flow of the medium flowing from the inlet to the outlet and are rotatable relative to one another for controlling the flow of the medium, in order to avoid friction and wear between the throttle devices and to assure a closing position without leakage flows, the throttle devices are embodied as hollow cones, with a cone jacket including at least one flow window, and the cones are disposed concentrically to one another in such a way that in the closing region of the throttle assembly, they are displaced axially toward one another by displacement means.
