Document Type and Number:
Japanese Patent JP3643122
Kind Code:
B2
Abstract:
A pressure balance or proportioning valve which comprises a disk-shaped mobile unit (10) having a pair of cylindrical shells (12) extending from each side of the mobile unit (10) which is axially movable in a bore (2) of a housing which contains hot and cold water inlet (5) and outlet (3, 4) pipes. The housing includes hot and cold water outlet pipes (3, 4), a cold water inlet (5) or supply pipe in one end of the bore, and a hot water inlet (5) or supply pipe at the other and opposite end of the bore. The hot and cold water supply pipes terminate in end walls (7) and have cylindrical side walls (13) adjacent the end walls with openings (14) extending radially through the cylindrical side walls (13). The mobile unit (10) is disposed intermediate the end walls (7) and moves axially, in response to unequal water pressure, in the bore between the end walls (7). Movement of the mobile unit (10) results in the cylindrical shells (12) either blocking or uncovering the radially extending openings (14) thereby equalizing the amount of hot and cold water entering the hot and cold water outlet pipes.
