A device for distributing compressed air from a compressed air source to a plurality of apparatus that use compressed air. The device comprises a housing having valve chambers, inlet ports for connecting the valve chambers to the compressed air source, outlet ports, and exhaust ports communicating with outside the device. Each outlet port is adapted to communicate with at least one of the apparatus that use compressed air. Spherical valve bodies movably are provided in the valve chambers, respectively, each for closing one inlet port and one exhaust port. Shafts extend from the valve bodies, respectively. Each shaft has an end portion passing through one exhaust port and protruding from the housing. Electromagnetic actuators are coupled to the end portions of the shafts, respectively. Each actuator moves one valve body between an air-supplying position where the valve body closes the exhaust port and connecting the inlet port and the outlet port and an air-exhausting position where the valve body closes inlet port and connecting the outlet port and the exhaust port.

Dispositif de distribution d'air comprimé provenant d'une source de production d'air comprimé. Le dispositif, qui alimente de nombreux appareils utilisant de l'air comprimé, comprend un logement doté de chambres de clapet, d'orifices d'entrée raccordant les chambres de clapet à la source de production d'air, d'orifices de sortie et d'orifices d'échappement communiquant avec l'extérieur du dispositif. Chaque orifice de sortie est adapté de façon à communiquer avec au moins un des appareils utilisant de l'air comprimé. Des corps de clapet sphériques et mobiles sont prévus dans les chambres de clapet, respectivement; chaque corps sert à fermer un orifice d'entrée et un orifice de sortie. Une tige s'avance entre les corps de clapet respectifs. Chaque tige comprend une extrémité qui passe à travers un orifice d'échappement et sort du logement. Un actionneur électromagnétique est raccordé aux extrémités des tiges. Chaque actionneur fait passer un corps de clapet d'une position d'alimentation en air, position dans laquelle le corps ferme l'orifice d'échappement et raccorde l'orifice d'entrée et l'orifice de sortie, à une position dans laquelle il ferme l'orifice d'entrée et raccorde l'orifice de sortie et l'orifice d'échappement.
