PRESSURE FEED UNIT. |
| abstract |
The invention relates to a pressure supply unit for an aerosol can, said unit being fixed to a gas cartridge (41). The unit comprises a chamber pressurized to the desired pressure of the bomb, a wall of the chamber is a membrane (33) and is connected to a needle valve (35) regulating the flow of gas from said cartridge (41) . A decrease in the pressure of the bomb causes the membrane (33) to move the needle to release gas from the cartridge (41). |
