Description of CVN Dispenser Operation
With the air solenoid valve OFF,The air piston and pilot plunger rises (up) under the force of spring.
The main plunger stops at the top point due to difference in the area receiving the pressure.
In this case, the grease comes through the inlet into the bottom side of the main plunger for filling.
2 Pilot Plunger goes down
When the air solenoid valve is turned ON, the air comes from the top of air cylinder, lowering the pilot plunger, Accordingly,the grease that has come through the inlet flows through the upper pass to come in the top of main plunger. On the other hand, the lower pass of main plunger is connected to the discharge port.
3 Dispensing process (Main plunger goes down)
The discharge port opens to the atmosphere, so that the main plunger lowers under the grease pressure, dispensing the grease filled in the lower chamber.
4 Pilot Plunger goes up
With the solenoid valve OFF, (with the top side (A) opening to the atmosphere). The pilot plunger rises along with the air piston. Under the force of spring.
Accordingly, the grease flowing through the inlet comes the bottom side of main plunger, and the main plunger rises due to difference in the area receiving the pressure.
In the case, the dispenser draws back the fluid accumulating in the discharge port, Preventing fluid dripping.
The function is called “Suction back”.
