FIELD: engines and pumps.
SUBSTANCE: invention relates to dispersion of liquids by compressed gas. The pressure regulation device is arranged in the container for liquids and is designed to keep up a constant preset surplus pressure. The device contains a cylinder, a piston arranged reciprocating inside the cylinder and limiting the first chamber filled by gas for application of preset surplus pressure. There is also the second chamber, a passage from the second chamber outside the device, a valve passing in the container for opening and closing the passage. The second chamber is a high pressure container with a closed end face and an open end face furnished with a rim. The said rim accommodates the cover to close the second chamber. The high-pressure container envelopes the cylinder of the first chamber which makes a part of the cover.
EFFECT: simpler design, creation and adjustment of the pressure.
