Title: (EN) Thermostat valve arrangement with magnetic locking device and a cooling system for combustion engine driven vehicles
Abstract: front page image
(EN)

A thermostatic valve aggregate for a motor vehicle cooling system, having a valve housing containing a valve seat, further having an expansible drive element which is configured in the valve housing and is coupled to a valve element, and a spring biasing the valve element against the valve seat, one coolant hookup on each side of the valve seat, a bypass valve element prestressed by a bypass valve spring in the direction of a bypass valve seat in order to selectively link one bypass hookup to the valve housing to one of the other hookups, characterized

in that an electromagnet is mounted on the valve housing and comprises a core extending as far as the bypass valve seat, in that the bypass valve element is fitted with a magnetically effective armature element resting against or nearly reaching the core when the bypass valve rests against the bypass valve seat.
