Abstract

1. Procedimento per il pilotaggio di un regolatore elettropneumatico.2.1. Procedimenti del genere servono al pilotaggio di un regolatore elettropneumatico, la cui camera operativa può essere collegata mediante due valvole elettromagnetiche ad una sorgente di depressione o ad una sorgente di pressione. In questo procedimento esiste l'inconveniente che per regolazioni rapide occorrono grandi sezioni di valvola, con le quali non si possono realizzare con sufficiente sensibilità regolazioni lente, a causa dei tempi di valvola troppo brevi.2.2 Il nuovo procedimento prevede di conseguenza che le due valvole elettromagnetiche vengano azionate ciclicamente, nel caso di una registrazione necessariamente lenta del regolatore, con la stessa frequenza e con un rapporto di tastatura variabile per ciascuna valvola.2.3 Il procedimento rende possibile registrazioni di velocità del regolatore praticamente a piacere, in base ad un pilotaggio sensibile nel caso di basse velocità di regolazione e si presta per un dispositivo destinato all'azionamento automatico di una frizione di autoveicolo.1. Procedure for piloting an electro-pneumatic regulator. 2.1. Such procedures are used to pilot an electro-pneumatic regulator, whose operating chamber can be connected by means of two electromagnetic valves to a depression source or to a pressure source. In this procedure there is the drawback that for rapid adjustments large valve sections are required, with which slow adjustments cannot be carried out with sufficient sensitivity, due to too short valve times.2.2 The new procedure consequently provides that the two valves electromagnetic are cyclically activated, in the case of a necessarily slow adjustment of the regulator, with the same frequency and with a variable probing ratio for each valve. 2.3 The procedure makes it possible to regulate the speed of the regulator practically at will, based on sensitive control in the case of low adjustment speeds and is suitable for a device intended for the automatic actuation of a vehicle clutch.
