REGULATORS AND FEED SYSTEM Russian patent published in 2014 - IPC F04B49/03 F04B19/00 

FIELD: process engineering.

SUBSTANCE: invention relates to regulator and/or its parts or components, for example, in air-driven tool feed systems. In compliance with some versions, two-step regulators feature every adjustable and/or readjustable step. In some preferable versions, adjustable and/or readjustable two-step regulators can be used selectively at low and/or high pressure and intermittent flow feed and continuous flow feed and/or low and/or high flow feed rate, or combinations thereof. In some versions, regulators feature stable operating parameters irrespective of pressure feed cylinder. In compliance with some versions, regulators incorporate selector of pressure fed to regulator inlet and, respectively, to connected hose, optional pressure gage to control outlet pressure. Also it can incorporated special cartridge "fed-discharged" cartridge as high-pressure cartridge and/or module.

EFFECT: stable gas feed.
