Valve Device

摘要

A valve device having a valve housing, through which passes a fluid channel, in which are formed a valve seat and a valve member which is accommodated such that it can be moved relative to the valve seat, having an electromechanical actuating means for moving the valve member between at least two functional positions in order to influence a free cross-section of the fluid channel, and having a control device, which is designed for activating the actuating means depending on a control signal and comprises a delay means which, in the case of the valve being switched off, is designed for a time-delayed movement of the valve member into a switch-off position. The control device and the delay means are designed in the form of electric circuits and include an electrical energy store which, in the case of the valve being switched off, is designed for energy-independent movement of the valve member into the switch-off position.

1. A valve with a valve housing, through which passes a fluid passage, in which are formed a valve seat and a valve member accommodated so that the valve member may be moved relative to the valve seat, with an electro-mechanical actuating means for moving the valve member between at least two functional positions in order to influence a cross-section of the fluid passage, and with a control device which is adapted to activate the actuating means on the basis of a control signal and which includes delay means which, in connection with a valve switch-off process, are adapted for delayed-action movement of the valve member into a switch-off position, wherein the control device and the delay means are adapted as electrical circuits and include an electrical energy storage which, in the case of a valve switch-off process, is adapted for an energy-autarkic movement of the valve member into the switch-off position.
