Patent number: 7382220Abstract: An ignition coil for an internal combustion engine has a rod-shaped magnetic core, which collaborates with a cushioning element in the axial direction. The magnetic core and the cushioning element are furthermore inserted into a secondary coil shell. Moreover, the coil shell has an ignition coil housing, which is filled at least partially with an epoxy resin. In order to avoid that the epoxy resin gets into the gap between the coating and the magnetic core, the cushioning element is developed as a sealing element at the same time. At the same time, the secondary coil shell has a coating on its inner wall for the accommodation of radial stresses. The ignition coil thus designed is developed to be relatively compact, and has good thermomechanical properties.Type: GrantFiled: December 22, 2006Date of Patent: June 3, 2008Assignee: Robert Bosch GmbHInventor: Wolfgang Keller
