ルブの安全装置。[Scope of claims for utility model registration] (1) Controlling the actuator with an electronic control circuit,
In an engine control valve mechanism in which the actuator operates a throttle valve and the actuator is controlled by an electronic control circuit, a negative pressure chamber is defined by a diaphragm and communicates with the downstream side of the intake passage;
An actuator drive characterized in that it has a valve that varies the cross section of the intake passage in conjunction with the diaphragm, and means that is operated by the electronic control circuit and that introduces atmospheric air into the negative pressure chamber only when the actuator fails. Throttle valve safety device. (2) Utility model registration claim No. 1, characterized in that magnets that attract each other are attached to the negative pressure chamber side of the diaphragm and the member forming the negative pressure chamber.
A safety device for the actuator-driven throttle valve described in (1).
