Attachable rod ignition coil
The invention relates to an attachable rod ignition coil comprising an ignition coil part and an adapter provided with an ignition plug receiving element for fixing the adapter to an ignition plug. A shock-absorbing element is arranged between the ignition coil part and the adapter and/or between the adapter and the ignition plug receiving element.
1. An ignition coil component attachable to a spark plug, comprising:
electrically conductive means connected to said ignition coil component provided with a socket for receiving a spark plug; and
shock absorbing means disposed in said socket engageable by said spark plug upon insertion thereof in said socket,
wherein said electrically conductive means includes means for yieldably attaching said spark plug to said electrically conductive means when said spark plug is received in said socket in engagement with said shock absorbing means.
2. A component according to claim 1 wherein said shock absorbing means is electrically conductive.
3. A component according to claim 1 wherein said shock absorbing means comprises at least one material selected from the group consisting of plastics, rubber, silicon metal, ceramic and sintered material.
4. An ignition coil attachable to a spark plug, comprising:
electrically conductive means connected to said ignition coil component provided with a socket for receiving a spark plug; and
shock absorbing means disposed in said socket engageable by said spark plug upon insertion thereof in said socket,
wherein said socket of said electrically conductive means includes a peripheral recess for receiving a portion of said shock absorbing means and thereby retaining said shock absorbing means in said socket of said electrically conductive means.
5. A component according to claim 4 wherein said shock absorbing means is provided with a disk-shaped configuration.
6. An ignition coil component attachable to a spark plug, comprising:
an adapter mounted on said component and displaceable relative thereto along a line of traverse, having a socket disposed therein for receiving the head portion of said spark plug; and
shock absorbing means disposed on said line of travel between said adapter and one of said component and said head portion of said spark plug when said head portion is received within said socket,
wherein said adapter includes a second recess disposed along said line of travel, said component includes a portion received in said second recess and said shock absorbing means is disposed in said second recess between said portion of said component and said adapter.
7. A component according to claim 6 wherein said adapter includes means for detachably securing said head portion of said spark plug in said second recess.
8. A component according to claim 6 wherein said adapter is formed of an electrically conductive material.
9. A component according to claim 6 wherein said shock absorbing means is formed of an electrically conductive material.
10. A component according to claim 6 including a second shock absorbing means disposed between said component and said adapter.
11. A component according to claim 6 wherein said second shock absorbing means comprises an annular member received in annular recesses in said component and said adapter.
12. An ignition coil component attachable to a spark plug, comprising:
an adapter mounted on said component and displaceable relative thereto along a line of travel, having a socket disposed therein for receiving the head portion of said spark plug; and
shock absorbing means disposed on said line of travel between said adapter and one of said component and said head portion of said spark plug when said head portion is received within said socket,
wherein said adapter having a recess includes an annular recess and said shock absorbing means is retained in said annular recess.
13. A component according to claim 6 wherein said shock absorbing means comprises a spring.
