Abstract

Il gruppo valvolare comprende due valvole di intercettazione (V1, V2) fra un raccordo di ingresso (1) destinato ad essere collegato ad un compressore, e due raccordi d'uscita (21, 22) destinati ad essere collegati ai due circuiti frenanti dell'impianto di frenatura. Le uscite di tali valvole di intercettazione possono essere accoppiate agli ingressi di altre due valvole di intercettazione (V3, V4) attraverso due valvole supplementari (I1, I2) a pressione di apertura fissa e più bassa della pressione di apertura di dette valvole di intercettazione (V1 - V4). Dette seconde valvole di intercettazione (V3, V4) sono destinate ad essere collegate in uscita ad un dispositivo dì frenatura e di stazionamento e, rispettivamente, a dispositivi pneumatici ausiliari dell'impianto di frenatura. (Figura 1).
