FIELD: machine building.
SUBSTANCE: valve mechanism for aportable gas supply system consists of a primary inlet hole, a primary outlet hole, a control, a secondary inlet hole and a secondary outlet hole. The primary inlet hole is adapted for connection to a gas bottle. The primary outlet hole has a hydraulic connected to the primary inlet hole and adapted for connection to one or more elements for gas supply from the gas bottle. The control is arranged between the primary inlet hole and the primary outlet hole for reduction of pressure of gas supplied from the gas bottle to the primary inlet hole. The secondary inlet hole has a hydraulic connection to the primary outlet hole. The secondary outlet hole has a hydraulic connection to the primary outlet hole and the secondary inlet hole. Secondary inlet and outlet holes are adapted for connection of the valve mechanism to one or more gas bottles.
EFFECT: use of the proposed invention will allow providing continuous and uninterrupted gas supply.
