Motor und Steuerventilanordnung mit reduzierter Variabilität der Betriebsüberzeit

摘要

A control valve assembly includes a one-piece valve movable between a first position at which the valve closes a seat defined by a housing and positioned fluidly between a fluid inlet and a first fluid outlet, and a second position at which the valve is out of contact with the seat. The valve includes an outer diameter having an annular seating shoulder located thereon which is configured to contact a frustoconical surface of the seat when the valve is at the first position, and the annular seating shoulder is further configured to deform in response to contacting the frustonical surface without changing a seating diameter associated therewith. Closing the seat with the annular seating shoulder reduces performance variability of the valve over time.
