2.1.2.5. The oil operating valve (OCV)

Fig. 2.37. Design of the oil managing director of the valve (OCV): 1 – spool-type valve; 2 – spiral; 3 – plunger; 4 – returnable spring

The oil operating valve (OCV) consists of the spool-type valve which changes oil channels, an electromagnet which moves the spool-type valve, a plunger and a returnable spring (fig. 2.37).
