ABSTRACT:
An internal combustion engine control system having a source of vacuum and a vacuum operated control device. A vacuum operated temperature controlled valve construction is provided for interconnecting the source to the device when the construction senses a certain temperature, the construction having means for only disconnecting the source from the device when the value of the source falls below a certain level thereof regardless of the temperature being sensed. The valve construction has a temperature operated pilot valve arrangement for actuating the valve construction to an open condition thereof when the certain temperature is sensed, the pilot valve arrangement including a snap acting bimetal disc for opening and closing a pilot valve seat thereof.
