Glow plug with a sleeve to receive the heating rod, equipped with a distal turned-up part

摘要

The invention concerns a glow plug comprising a heating rod (11), a plug body (13) having a receiving housing (14) of the heating rod, a receiving sleeve (16) which is fixed rigidly and impermeably to the proximal portion of the heating rod, and a load sensor (17). The receiving sleeve (16) has a distal extremity portion which is turned up on the proximal side towards the exterior, and connected rigidly and impermeably to the plug body, so as to form a turned-up part (26) which is elastic in flexion and impermeable.
