FIELD: power engineering.
SUBSTANCE: invention relates to power engineering, to valves and fuel feed systems from low-pressure tanks in various fields of technology. Pneumatically operated fuel valve comprises bellows drive with control pressure feed branch pipes. Spring with bellows is fitted in its housing, rod with shutoff element and seat. At that, bellows drive with rod and shutoff element is installed in fuel tank and is fixed by supports above seat made around tank intake, and housing of bellows drive is tightly connected by sealing bellows with rod coming out of it.
EFFECT: invention is aimed at reduction of hydraulic resistance at outflow of working medium from tank, reduction of total weight of valve and possibility of operation at cryogenic temperatures of working medium.
