What are the internal parts of a power plunger?
What are the internal parts of a power plunger? |

 |
||||
Air chamber |
||||
 |
The air chamber is where the compressed air, which has been pumped into the chamber by the pump, is held until it is released by the trigger. | |||
Pressure relief valve |
||||
 |
The pressure relief valve allows the user to release some of the compressed air into the cylinder to be released out.
This is useful for clearing fragile or delicate plumbing, as the pipework may not require a great amount of pressure (as there is a possibility of it damaging or breaking the pipework), so by turning the valve, some of the built-up pressure will be released. |
|||
Differential release valve |
||||
 |
The differential release valve is activated when the trigger is pulled. The differential valve, when activated by the trigger, activates the pressure release valve, resulting in the pressure from the cylinder being released out of the air chamber, | |||
One way valve |
||||
 |
The one way valve (non return valve) allows air to flow into the cylinder, but has a rubber diaphragm to stop the air flowing back out through the valve again. When the trigger is pulled to activate the differential valve, the non return valve stops any built up pressure escaping back up and into the pump. | |||
O ring seal |
||||
 |
The O ring seal is fitted and sits where the pump and trigger section meets the air cylinder.
The O ring seal provides an airtight seal to stop any air pressure escaping between the two joining parts. It also prevents moisture from entering the power plunger when in use, protecting the internal parts. |
