ABSTRACT:
A piezoelectric high voltage impact mechanism is actuated electrically. The impact results from momentary actuation of a wire coil mounted in a magnetic frame. The force on the armature or hammer with electric power connected causes virtual closure of the magnetic circuit as the hammer strikes the adjacent end means of the piezoelectric element means. The resulting stress wave generates a high voltage transient which may be used to ignite gas appliances. The housing for piezoelectric element means is fastened to the magnetic frame. The coil is actuated from a relatively low voltage a-c or d-c power source. When the electric power source is disconnected from the coil the hammer or armature is returned to its initial position by a return spring or the force of gravity.
