FIELD: ventilation.

SUBSTANCE: air consumption stabilisation device contains a housing 1, with a control valve designed as a fixed cylinder 2 with cuts in a lateral surface 3 and a plunger 4 with a limit stop 5 installed in the cylinder 2 with a possibility of reciprocating movement. The air flow pressure makes the plunger 4 move inside the cylinder 2. The cylinder is installed on the orifice 6 which is rigidly fixed on the housing 1. The elastic element 7 is fixed by one end on the plunger 4, by another one - on the tension adjustment screw 8 installed on the stand 9 fixed in the housing. The tension adjustment screw 8 adjusts the necessary tension of elastic element.

EFFECT: simplification of design and exception of spatial orientation of the air consumption stabilisation device, operation without external power source.
