FIELD: machine building.
SUBSTANCE: invention relates to devices spraying the content at a high pressure. The aerosol package contains an adjusting valve to reduce internal pressure inside the package filled with a compressed gas to a preset level the spraying valve operates at. Here, the adjusting piston is kept by the return force in equilibrium. The device incorporates a seal closing at the pressure in the adjusting chamber exceeding the preset pressure value. To avoid inaccuracy of pressure adjustment possible due to inner pressure reducing inside the package with the consumption, the package is furnished with a tightening seal. The said seal isolated the piston free end relative to the package inner pressure and the preset pressure.
EFFECT: higher adjustment accuracy.
