Abstract

LOS DISPARADORES ELECTROMAGNETICOS RAPIDOS CON VASTAGO DE PERCUSION Y CON UNA BOBINA DE DISPARO ELECTRICA, CUYO DEVANADO ES RECORRIDO POR UNA CORRIENTE DE CARGA, POSEEN UN IMAN PERMANENTE RELATIVAMENTE GRANDE, QUE MANTIENE EL VASTAGO DE PERCUSION EN LA POSICION TENSADA CONTRA LA FUERZA DE UN RESORTE. LA ELEVADA FUERZA DE RETENCION DEL IMAN PERMANENTE INFLUYE DESFAVORABLEMENTE EN LA CARACTERISTICA DEL RESORTE, CUANDO SE TENSA EL DISPARADOR. EL DISPARADOR RAPIDO SE CONSTRUYE POR ELLO DE TAL FORMA, QUE AL TENSAR EL DISPARADOR SE OBTENGA, POR UN LADO, UNA CARACTERISTICA FAVORABLE DEL RESORTE Y, POR OTRO, UNA FUERZA DE RETENCION GRANDE CON UN VOLUMEN MINIMO DEL IMAN. PARA ELLO SE PREVE, QUE EL NUCLEO (4) MAGNETICO TENGA LA FORMA DE UN CASQUILLO TUBULAR DE MATERIAL FERROMAGNETICO, QUE SOBRESALE DE LA PLACA POLAR (5) INFERIOR DE LA CARCASA (3) DEL IMAN Y QUE ATRAVIESA COAXIALMENTE LA BOBINA (2) DE DISPARO EN TODA SU LONGITUD. EL VASTAGO (6) DE PERCUSION ES DE MATERIAL NO MAGNETICO. EL IMAN (8) PERMANENTE SE MONTA EN EL VASTAGO (6) POR ENCIMA DE LA BOBINA (2) CON UN ENTREHIERRO (20) CON RELACION A LA PARED DE LA CARCASA (3). EN EL ESTADO TENSADO DEL DISPARADOR RAPIDO SE CIERRA EL CIRCUITO MAGNETICO (22) ENTRE EL IMAN (8), EL NUCLEO (4), LA PLACA (5) Y UNA PARTE (3A) DE LA CARCASA (3), QUE RODEA LA BOBINA (2). EN EL ESTADO DESACTIVADO O NO TENSADO SE CIERRA EL CIRCUITO MAGNETICO (22A) A TRAVES DEL IMAN (8) Y DE UNA PROLONGACION (15) SUPERIOR Y MAS ESTRECHA DE LA CARCASA. CON ESTA CONSTRUCCION SE PUEDE SIMPLIFICAR TAMBIEN CONSIDERABLEMENTE EL MONTAJE DEL DISPARADOR RAPIDO.THE RAPID ELECTROMAGNETIC TRIGGERS WITH A PERCUSSION STEM AND AN ELECTRIC TRIP COIL, WHOSE WINDING IS TRAVELED BY A LOAD CURRENT, POSSESS A RELATIVELY LARGE MAGNET, WHICH MAINTAINS THE POSITIONAL ROD OF A PERCUSSION IN THE POSITION OF THE POSITION. THE HIGH RETENTION FORCE OF THE PERMANENT MAGNET UNFAVORABLY INFLUENCES THE SPRING CHARACTERISTIC, WHEN THE TRIGGER IS TAKEN. THE FAST TRIGGER IS BUILT THEREFORE IN SUCH A WAY, THAT BY TENSIONING THE TRIGGER, A FAVORABLE SPRING FEATURE IS OBTAINED, AND, ON THE OTHER, A LARGE RETAINING FORCE WITH A MINIMUM VOLUME OF THE MAGNET. FOR THESE PROVISIONS, THE MAGNETIC NUCLEUS (4) SHOULD HAVE THE SHAPE OF A TUBULAR BUSHING OF FERROMAGNETIC MATERIAL, PROJECTING FROM THE POLAR PLATE (5) BOTTOM OF THE CASE (3) OF THE MAGNET AND COAXIALLY CROSSING THE COIL (2) OF TRIP IN ALL ITS LENGTH. THE PERCUSSION STEM (6) IS OF NON-MAGNETIC MATERIAL. THE PERMANENT MAGNET (8) IS MOUNTED ON THE STEM (6) ABOVE THE COIL (2) WITH A GAP (20) IN RELATION TO THE HOUSING WALL (3). THE MAGNETIC CIRCUIT (22) CLOSES BETWEEN THE MAGNET (8), THE NUCLEUS (4), THE PLATE (5) AND A PART (3A) OF THE CASE (3), THAT SURROUNDS THE COIL (two). IN THE DEACTIVATED OR NON-TENSIONED STATE, THE MAGNETIC CIRCUIT (22A) IS CLOSED THROUGH THE MAGNET (8) AND A SUPERIOR AND TIGHTEST EXTENSION OF THE HOUSING. WITH THIS CONSTRUCTION THE FAST TRIGGER ASSEMBLY CAN ALSO BE CONSIDERABLY SIMPLIFIED.
