Poppet valve has body in which pressure and vacuum plates are mounted on the same axle. Valve is provided with one inlet and one outlet for use in closed systems. Plates are spring-loaded in opposition. Seats are made compact in pairs separately for pressure and vacuum, symmetrically on one intermediate element. Pressure plate is provided with holes for interaction with vacuum gate. Pressure and vacuum plates are made for counter interaction. Valve makes it possible to inhale vapours settled in closed system and to return them to reservoir. EFFECT: improved environment protection. 1 dwg
