FIELD: transport engineering; vehicles powered by engines operating on gaseous fuel.
SUBSTANCE: proposed multiway valve has housing with intake tubular channel connected by one end with liquid gas charger, and by other end, with tank and outlet tubular channel equipped with devices to control flow of liquid gas flow into tank and from tank. Valve contains also electronic level pickup installed in tank which is connected both with cutoffs of inlet and outlet gas flows and with tank charging level indicator controlled by control unit. Two shutoff valves are installed along intake tubular channel, respectively, first and second ones, upflow and downflow relative to intake electromagnetic valve. Pressure pickup is arranged downflow relative to charger and upflow relative to first shutoff valve. Flow limiter, two-position manually controlled valve and outlet electromagnetic valve are installed along outlet tubular channel.
EFFECT: improved accuracy and reliability of checking level of tank filling, and safety of device.
