An automatic dispenser for injecting starting fluid into an internal combustion engine is disclosed. This dispenser includes a valve actuator which is adapted to receive a valved cannister containing a pressurized starting fluid and to pass starting fluid from the cannister through a conduit to an injector positioned in an air intake passage of the engine. The valve actuator is coupled to the starting system of the engine so that the cannister valve is continuously injected into the engine during operation of the engine\s starter motor. In this way a continuous flow of starting fluid is automatically dispensed during engine cranking. The valve actuator is also provided with a reservoir which temporarily stores a predetermined volume of starting fluid while fluid is flowing through the actuator, and then supplies this fluid to the injector after the cranking has stopped, thereby providing starting fluid to the engine during the period immediately following termination of cranking. In addition, an electrical circuit for manually controlling the valve actuator and improved reservoirs are also described.

An apparatus for automatically injecting a pressurized starting fluid from a valved cannister into an air intake passage of an internal combustion engine provided with starter means, said apparatus comprising: a valve actuator having an intake bore coupled to the valved cannister and an exit bore, said valve actuator, when activated, operating to pass starting fluid continuously from the valved cannister, through the intake bore, to the exit bore, said actuator including a coil and a movable armature disposed adjacent the coil to actuate the cannister valve when electrical current is passed through the coil; means for conducting starting fluid from the exit bore of the valve actuator to the air intake passage; reservoir means in fluid communication with the exit bore for temporarily storing a volume of starting fluid during the period when the valve actuator is activated, and for supplying the volume of starting fluid to the air intake passage immediately following de-activation of the valve actuator, said reservoir means including a cavity formed in the armature; means for venting the cavity formed in the armature to increase the volume of starting fluid temporarily stored in the cavity; and means for automatically activating the valve actuator during operation of the starter means, such that the valve actuator is automatically controlled to cause starting fluid to be injected into the air intake passage during and immediately following operation of the starter means.
