Abstract

PERFECCIONAMIENTOS EN UN SENSOR DE PICADO PARA LA FIJACION DIRECTA O INDIRECTA EN UN MOTOR DE COMBUSTION. EL SENSOR DE PICADO PARA LA FIJACION DIRECTA O INDIRECTA EN UN MOTOR DE COMBUSTION PRESENTA UNA CARCASA (10) CON UNA CAPSULA A PRESION (11) SOBRE CUYA CARA EXTERIOR SE HAN DISPUESTO UN DISCO PIEZOCERAMICO (14) Y UNA MASA SISMICA (16) QUE ACTUA SOBRE EL PRIMERO. ESTAS PIEZAS SE PONEN EN CONTACTO POR UN MUELLE DE PLATO (17), CON DISCOS DE CONTACTO (13, 15) PRODUCIENDOSE LA PRETENSION DE DICHO MUELLE MEDIANTE UN ANILLO ROSCADO (18) SOBRE LA CAPSULA A PRESION. DE ESTA MANERA SE PUEDE REGULAR A ELECCION LA FUERZA EJERCIDA SOBRE EL DISCO PIEZOCERAMICO.
