CVM Precise Fluid Dispenser

Pilot block and main block are separated. Discharge volume can be changed by exchange only main block while pilot is left as it is.

Selling unit is one set.(Pilot Block + Main Block) Us to 4 blocks can be combined as one assembled body by utilizing tie bolts.

Large, middle small valves can be combined as one assembled body.

Pilot plunger is of double action type, hence 5-way air solenoid valves shall be applied.

Description of the Operation of CVM Dispenser

1 Standby

  • Description of the Operation of CVM Dispenser 1 Standby
  • With the air solenoid valve OFF, the air comes in the air cylinder from its bottom (B).The top side (A) is open to the atmosphere. 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

  • Description of the Operation of CVM Dispenser 2 Pilot Plunger goes down
  • When the solenoid valve is turned ON, the air comes from the top (A) of air cylinder, lowering the pilot plunger, Accordingly, the grease that gas com 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)

  • Description of the Operation of CVM Dispenser 3 Dispensing process
  • The discharge port opens to the atmosphere, so that the main plunger lowers under the grease pressure, dispensing the grease filled the lower chamber.

4 Pilot Plunger goes up

  • Description of the Operation of CVM Dispenser 4 Pilot Plunger goes up
  • With the solenoid valve OFF, the air comes through the bottom (B) of the air cylinder (with the top side (A) opening to the atmosphere). The pilot plunger rises along with the air piston.
  • 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"
