Claims

[Claims for Utility Model Registration] (1) A fuel restriction mechanism for an automatic start/stop device that automatically starts and stops a diesel engine using aerodynamic force, in which the piston that slides under the aerodynamic force is approximately cylindrical. A speed regulating valve for limiting the flow rate of air flowing to the air chamber is provided in the main body of the main body, and is integrated with the main body in an air circulation passage connected to an air chamber in the main body, and the speed regulating valve controls the fuel flow. A fuel limiting mechanism with a built-in speed regulating valve, characterized in that the operating speed of the limiting mechanism is limited. (2) A speed adjustment valve is a throttle valve that changes the throttling rate of air flow by adjusting the minute gap between the conical valve body and the valve seat, and releases air leaking from the minute gap to the outside. A fuel limiting mechanism with a built-in speed regulating valve according to claim 1 of the utility model registration claim, in which a relief hole is formed.
