ABSTRACT: A rotation speed control apparatus for an internal combustion engine has a signal-responsive diaphragm, whose position is determined by a negative pressure signal and which controls the opening of a throttle valve. If the signal is found to be abnormal, the diaphragm is rendered substantially inoperable, so that the throttle valve can be restored to a safe position, hence avoiding the risk of improper operation of the engine in the event of a malfunction of the diaphragm or other aspect of the pressure sensitive control system.
