Pressure-balancing distributing valve with selective cutoff for tyres of twin wheels of motor vehicles equipped with an onboard minimum-pressure warning system

摘要

A valve comprising a distributor body (20) with a single collector (21) having, at one end, a cap valve (22) connectable to a source of compressed air, and at the other end sealing coupling means for connection to the electropneumatic transducer of a warning system; a pair of distribution ducts (25-26) extending from said collector and ending with corresponding tangs for the insertion of the tubes leading to the tires and a pair of valve bodies (29-30) pushed to open by the inflation pressure and actuated by an adjustable spring (37) so that each cuts off its corresponding derived duct, to cutoff the connection between the two tires, when the action of the pressure becomes smaller than the load of the spring.
