Abstract

Abstract Break ignition plug and ignition device for piston motors and the like with a battery or any other current supply means, wherein a magnet coil acts upon an armature which, via connection means, actuates a movable electrode cooperating with a stationary electrode and wherein an ignition pulse passes through the magnet coil and a short-circuit line section between the movable and the stationary electrode, the magnet field building up in the magnet coil causing the breaking of the short-circuit line section with corresponding spark formation as well as an air supplying device which allows for better atomization of the fuel. The armature, and/or the connection means and/or the electrode are movable, in particular are rotatable, transversely with respect to the longitudinal axis of the ignition plug. At least one of the electrodes possesses a substantially saw-toothed shaped construction.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 146 words
A break ignition plug and ignition device, especially for piston motors, with a current supply means, comprising a movable electrode means cooperating with a stationary electrode means, armature means, connection means, a magnetic coil acting upon said armature means via said connection means to actuate said movable electrode means, an ignition pulse passing through the magnetic coil and a short-circuit path between the movable electrode means and the stationary electrode means, the magnetic field building-up in the magnetic coil causing the breaking of the short-circuit path with corresponding spark formation, the improvement comprising at least one of said electrode means being mounted to be rotatable through an angle of 360* with respect to the longitudinal axis of the ignition plug, and at least one of said electrode means possessing a substantially saw-toothed shaped construction cooperating with the other electrode means for the formation of ignition sparks.
Claim 2
Dependent Claim 146 words
A break ignition plug and ignition device, especially for piston motors, with a current supply means, comprising a movable electrode means cooperating with a stationary electrode means, armature means, connection means, a magnetic coil acting upon said armature means via said connection means to actuate said movable electrode means, an ignition pulse passing through the magnetic coil and a short-circuit path between the movable electrode means and the stationary electrode means, the magnetic field building-up in the magnetic coil causing the breaking of the short-circuit path with corresponding spark formation, the improvement comprising at least one of said electrode means being mounted to be rotatable through an angle of 360* with respect to the longitudinal axis of the ignition plug, and at least one of said electrode means possessing a substantially saw-toothed shaped construction cooperating with the other electrode means for the formation of ignition sparks.
Claim 3
Dependent Claim 24 words
