The OCV Oil Control Valve Structure of VVT System
The VVT system's OCV valve is a proportional valve, that is, the movement position of the spool is proportional to the PWM duty ratio provided by the ECU of the engine to the OCV coil. When the duty ratio is gradually increased, the electromagnetic force of the coil is gradually increased, the iron core assembly moves in the solenoid, and the valve core is pushed forward against the spring force. When the duty cycle signal is gradually reduced, the electromagnetic force is gradually reduced. The spool gradually returns to its position under the action of the spring force. During the movement of the spool, the valve sleeve cooperates with the valve sleeve to realize the switching of the oil passage, thereby controlling the direction and flow of the oil into and out of the OCV valve, and controlling the flow of oil flowing into or out of the oil chamber of the phaser.
