Title:
HOTTWATER MIXING FAUCET
Document Type and Number:
Japanese Patent JPS55135277
Kind Code:
A
Abstract:
PURPOSE:To obtain always uniform proper temperature even if water pressure varies by arranging an automatic pressure cotrol valve which is held slidably inside the shell body, ON-OFF valve which is equipped with hot-water discharge port and arranged at the shell body projected part, and a temperature controller inside hot- water mixing chamber. CONSTITUTION:When hot water is established on the low temperature side, a cam 26 is operated, and a leaf spring 25 pushes a piston 14 through linkage parts 15 and 16, and an automatic pressure control valve 10 is moved rightward, and the conduction hole 121 on the hot-water side is narrowed by a pressure control valve 181, and the conduction hole 122 on the cold water side is widened by a pressure cotrol valve 182. While, when temperature is established on high-temperature side, the cam 26 is operated to the non-contact position with the leaf spring 25, and the spring pushes the piston 14, and the automatic pressure control valve 10 is moved leftward, and the hot-water conduction hole 121 is widened and the cold water conduction hole 122 is narrowed. If the difference of water pressure between hot water and cold water becomes large, the piston 14 is pushed to the low pressure side rapidly, and the automatic pressure control valve 10 is shifted against the leaf spring 25, and thus the always constant temperature of the hot water can be obtained.
