FIELD: transport engineering; pneumatic tires. ^ SUBSTANCE: invention can be used for inflating vehicle tires to required pressure by external compressed air source. Proposed device has housing with space with inlet hole for connection with compressed air source, and outlet hole for connection with space of pneumatic tire. Housing space is divided into working and discharge chambers by diaphragm with ring sealing member. Diaphragm is flexibly thrusted between end face walls of housing space so that working chamber is separated from discharge chamber until pressure difference in said chambers exceeds preset threshold value at which compressed air at inflating the tire starts escaping into atmosphere with specific hissing. There is no necessity to constantly check value of required pressure at inflating the tire. ^ EFFECT: improved convenience, simplified control at tire inflating. ^ 25 cl, 2 dwg |
