AIR HEATER FUSE FOR DIESEL ENGINES

Predmet izuma je varovalka grelnika zraka diesel motorjev. Vstopni zrak dizel motorjev je za lažji zagon motorja potrebno ogreti, zato je pri večjih dizel motorjih je v sesalni cevi vgrajen električni grelnik. Zaradi obstaja varovanje v primeru prekomernega električnega toka in segrevanja ohišja. Varovalka po izumu je značilna po tem, daje talilni vložek (9) na grelnik zraka pritrjena z pritrdilnim vijakom (5), pri čemer se talilni vložek (9) nahaja med glavo pritrdilnega vijaka (5) in ohišjem grelnika zraka (1) in je talilni vložek (9) izoliran od stebla pritrdilnega vijaka (5) z izolacijskim distančnikom (12a) ali drugim izolacijskim materialom. An air heater fuse for diesel engines for easier starting of a diesel engine inlet air needs to be warmed. In large diesel engines an electric heater is therefore installed into an inlet manifold due to protection in case of excessive electric current and warming of the housing. The fuse of the invention is characterised in that the fusible link (9) is fastened to the air heater by the fastening screw (5), wherein the fusible link (9) is arranged between the head of the fastening screw (5) and the housing (1) of the air heater, and the fusible link (9) is insulated from the shaft of the fastening screw (5) by the insulating spacer (12a) or another insulating material.
