Dosing valve

The invention relates to a metering valve which is particularly suitable for spraying aerosols and cosmetics.

According to the invention, this valve is designed so that for Entnaiiiie a predetermined hen ^ e too pressurized Medium from a container, a double valve in a Dooierkammer is arranged, which closes an outlet pipe in the cow position, while the dosing chamber via a riser with a Pressure vessel is in communication, with solidified: in the outlet position the outlet pipe connects to the Dosierkaaiaer and the connection of the Do3ierkaminer with the pressure vessel is blocked. The double valve is advantageously designed in such a way that, when actuated, the connection of the Do3iarkainiiier with your pressure vessel closes before the connection of the doser chamber with the outlet pipe is manufactured ..

By pressing the operating button 10, the valve rod a.

Through this mo- The sealing lining 6 is removed from the opening by the valve rod 8 of the outlet pipe 3 removed, bo that this comes with the interior of the metering chamber 1 in connection. The one in the dosing chamber 1 Pressurized medium flows out through the outlet pipe 3 until 'the pressure difference between the interior of the metering chamber 1 and the surrounding airspace is balanced. Now the pressure on the actuation button 10 is removed and the spring 11 moves the valve rod 8 back up so far that the opening of the outlet pipe 3 is closed by sealing lining 6 fen and the connection between the riser pipe 4 and the metering chamber 1 is restored

Two times, the elasticity of the sealing linings 6 and 7 or at least one of the two selected so that when the double valve 2 is actuated, the connection between the riser pipe 4 and the metering chamber 1 is interrupted before the connection of the outlet pipe 3 with the metering chamber 1 is established. This measure makes it possible to use the double
