SUBSTANCE: two-chamber diaphragm fitting consists of case, wherein there is positioned lower chamber, and upper part, wherein there is located upper chamber. An orifice connects the upper chamber with the lower one. Shutting-off element is designed to turn towards the fitting and rotates around the first axis between the first position and the second position. A pivoted lever turns towards the case of the fitting and is connected with the shut-off element so, that rotation of the pivoted lever around the second axis forces the said shut-off element to rotate around the first axis between the first and the second position.
