ABSTRACT:
In an electrically operated valve, a valve closure member, which lies in the path between the inlet channel and the outlet channel, is connected to an expansion member. At the time of electrical heating, the expansion member lifts the valve closure member from the associated valve seat, due to which the path for the flowing medium is cleared. A cooling member is located in an annular channel, into which, controlled by a regulating valve, different quantities of flowing medium can be introduced. The cooling member is thermally coupled to the expansion member. In this way, the expansion member, according to the position of the regulating valve, can be cooled to different degrees, due to which the response behaviour of the valve is variable in particular after switching-off the electric current.
