Abstract
1431359 Valves LEONARD VALVE CO 22 April 1974 [1 Oct 1973] 17485/74 Heading F2V A temperature adjusting and shut-off member 25 in a mixing valve has a chamber containing a freely movable valve member 54 with its opposite ends subjected to the opposing pressures of hot and cold water to maintain the flows through ports 15, 16 into a mixing chamber 9 at uniform pressure. When the valve is open, hot water from an inlet 2 flows through a passage 11 and a port 72 and around a closure member 65 into a space 10 from which it flows through ports 37 and 30 in the member 25 and the port 15, into the chamber 9. Cold water simultaneously flows from an inlet around a closure member 80 and through ports 38 and 31 to the port 16. The ports 37 and 38 are regulated by lands at opposite ends of the valve member 54 which has ports 55, 57 to permit the hot and cold water pressures to act within spaces 58 and 56. The member 25 has a screw-threaded engagement with the valve body and is designed so that cold water flows into the mixing chamber first.
