Abstract RU 2531480 C1

FIELD: machine building.

SUBSTANCE: in cut-off valve the correlation between elements of its design is introduced and also the functional interaction of the valve named elements is given. A feedback line in the cut-off valve is additionally connected with pressure source.

EFFECT: improvement of reliability of cut-off valve design at the expense of avoidance of a faulty actuation of the valve at movement of the movable piston due to severisation of the feedback line.

3 cl, 4 dwg
