Abstract:
A two-piece igniter, comprising:an outer housing including a cylindrical member having an outer wall and an inner wall, the inner wall defining a passage through the outer housing, the inner wall having a first profile defining a first diameter and a second profile defining a second diameter, the first profile having at least one undercut section; a plug member adapted to fit within the passage of the outer housing and including an axial electrode and an electrically insulating insulator element encircling the axial electrode, the axial electrode having a first end for connection to an electric source and a second end for engagement within a combustion area, the plug member having a first profile and a second profile, the second profile adapted to be received within the at least one undercut section of the first profile of the outer housing; and a longitudinally extending biasing member positioned about the plug member; and wherein the plug member may be releasably coupled within the outer housing by inserting the plug member within the passage of the outer housing and turning the plug member with respect to the outer housing, thereby locating the second profile of the plug member within the at least one undercut section of the first profile of the outer housing, and wherein the biasing member biases the second profile of the plug member into engagement with the at least one undercut section of the first profile of the outer housing.
