Abstract

Perfeccionamientos en dispositivos para indicar la presión de inflación insuficiente en las cubierta de vehículos, y del tipo que comprende una bobina emisora abastecida por un generador de señales a una frecuencia determinada, y una bobina receptora, alojándose las bobinas emisora y receptora sobre un soporte fijo del vehículo próximas a cada rueda rotatoria por lo que no pueden acoplarse de una forma inductiva sino que pueden acoplarse tan solo por un circuito de acoplamiento respectivo situado en cada rueda, cuyo circuito comprende una primera y una segunda bobinas de transferencia conectadas en serie con un contacto eléctrico accionado por un transductor sensible a los valores de la presión en la cubierta; situándose las bobinas de transferencia en la rueda de tal manera que permitan que la bobina receptora reciba periódicamente una señal alimentada por el generador a la bobina emisora cuando las bobinas de transferencia se encaran respectivante a la bobina emisora y a la bobina receptora y si el contacto eléctrico ha cerrado el circuito de acoplamiento debido a que la presión exceda de un valor mínimo establecido.
