Abstract

Viene descritto un dispositivo con transponder (26) per rilevare la pressione del pneumatico di una ruota di veicolo a motore che presenta una valvola (18). Il transponder (26) è accoppiato elettromagneticamente con un'antenna (30) che è prevista lateralmente accanto alla ruota (10) del veicolo in prossimità della traiettoria circolare della valvola (18) quando la ruota (10) del veicolo gira. Il transponder (26) è previsto su un elemento - pistone (24) che è disposto in un corpo (22) della valvola che può essere avvitata sulla valvola (18). Il corpo (22) della valvola è costituito di un materiale ad elevata permeabilità. Fra l'elemento - pistone (24) ed il corpo (22) della valvola è previsto un dispositivo a molla (66). Il corpo (22) della valvola e l'elemento - pistone (24) costituiscono una unità pistone - cilindro (20). L'elemento - pistone (24), quando è avvitato sulla valvola (18) è sottoposto alla pressione del pneumatico. Il dispositivo a molla (66) contrasta la pressione del pneumatico. Se la pressione del pneumatico cade al disotto di un valore critico di pressione l'elemento - pistone (24) viene sospinto dal dispositivo a molla (66) dentro il corpo (22) della valvola, cosicché il transponder (26) è schermato dal corpo (22) della valvola nei confronti del campo elettromagnetico (32) dell'antenna.(Figura 2).
