Abstract

In un sistema di alimentazione di pressione ad un dispositivo di commutazione automatico di un cambio di velocità viene inviata pressione di lavoro regolabile da un dispositivo di valvole a piú vie o soltanto ad organi di regolazione di due innesti di comando situati davanti al cambio di velocità o ad organi di regolazione di commutazione per l'azionamento di innesti che producono il flusso di forze all'interno del cambio di velocità dove, nell'ultimo caso, l'organo di regolazione di un innesto di comando è caricato da una pressione principale dipendente dal carico.
