FIELD: valve used in air cushions or mats for providing fluid communication between two or more zones, may be employed for isolation of zones and formation of structure to be connected to cushion.
SUBSTANCE: valve has slide valve casing provided between two outer housing halves. Each of housing halves has a plurality of receptacles of connector with nipples. Each of said receptacles has at least one outer stopper. Slide valve casing has a number of connectors arranged along its length and equipped with nipples. The latter are inserted into air pipes along peripheral edge of cushion and connected with individual inflation zones. Each connector with nipples has at least one holding slot provided on its surface. Stoppers of housing halves cooperate with cushion edge and holding slot for holding of nipple in air pipes. Movable slide valve is located within bore. Slide valve has inner longitudinal bore and a plurality of apertures provided along the entire length thereof. Apertures communicate with inner bore. Valve is opened to align slide valve apertures with connector equipped with nipples for communicating of inflation zones with each other through slide valve bore. Valve is closed for moving slide valve apertures from position in which slide valve apertures are out of alignment with housing apertures to thereby seal inflation zones.
EFFECT: increased efficiency in isolation of zones and formation of structure for connection to cushion so as to prevent shifting and leakage.
