Abstract
PURPOSE: To enable maintaining of output pressure of an outlet port, by a system wherein compressed air at an inlet port is exausted to two outlet ports, and the outlet port is closed whose pressure is reduced due to a difference in the pressure between two output pressure when the pressure of the other outlet port decreases.
CONSTITUTION: Compressed air fed to a main reservoir 22 through a duct 39 from an air compressor flows into an inlet port 4 whereat said compressed air is distributed to two outlet ports 5 and 6, the compressed air being fed from the outlet ports 5 and 6 to sub-reservoirs 23 and 24 through check valves 25 and 26, respectively. The compressed air fed to the reservoirs 23 and 24 is supplied to various types of pressure-operated devices through ducts 40 and 41, respectively, said compressed air, meanwhile, being fed to ports 15 and 14 of pressure chambers 13 and 12 through ducts 43 and 42, respectively. Thus the same pressure is applied to internal and external surfaces of each of pistons 7 and 8 which are held in a neutral position. A valve 1 is especially provided with a manual restoring device 2.
