FIELD: automation of test and control of municipal household equipment. SUBSTANCE: gas controller has a body with inlet and outlet branch pipes and valve with seat and with above- and under-valve spaces positioned between branch pipes. It also includes start button, blaster, burner, and transducers of draught, flame and controllable parameters, type "nozzle-flap". Under and above-valve spaces are separated by throttle valve formed by guaranteed microclearance between side wall of valve and the body. Blaster contains two nozzles. Above-valve space is coupled to the first nozzle of blaster through series-connected transducers of "nozzle-flap" type first through draught transducer and then through flame transducer. The second nozzle of blaster is also coupled to above-valve space through start-button nozzle. Flame transducer is connected simultaneously to outlet branch pipe of body or to injection space of burner through controllable-parameter transducer, type "nozzle-flap". Invention makes it possible to simplify construction, assembly and adjustment of controller. EFFECT: reduced overall dimensions, enhanced reliability of controller. 4 cl, 1 dwg
