Abstract:
A method for making a sheathed-element glow plug including a ceramic glow element, a contacting element, the contacting element including a pellet made of an electrically conductive powder, and a connecting element for supplying power and being electrically connected to the ceramic glow element via the contacting element, the method comprising the steps of:introducing a sealing gasket from a side tip of a combustion chamber of the ceramic glow element over the ceramic glow element and forming a composite; introducing the composite into a glow element housing; arranging components in a holding element, the components including an adapter sleeve, the connecting element, a ceramic sleeve, a metal ring and the pellet made of an electrically conductive powder; introducing the holding element into the glow element housing; pressing the components in the glow element housing using an axial force that is exerted on an end of the metal ring farther removed from the combustion chamber; and locking the metal ring using a force applied radially to the glow element housing from outside of it.
