<p>The press-button actuated valve is for a tin having a separate pressure compartment for the drive gas. The valve has separate channels (3, 4) for the gas and the fluid to be sprayed, which converge in the outlet nozzle (8). Valve elements (5-7) open and seal the gas channel (4). Another valve element (10) seals the outlet nozzle (8) and the fluid channel, when in neutral position, but is moved in the opening direction by the outflowing drive gas, when the gas valve elements are actuated. The fluid control valve element is hollow, sealed by a rear wall (13), and the drive gas flows into it.</p> |
