Inventor: TURNER ERNEST
IPC: G05D11/00
Filed: 1916-04-15
Abstract: 106,296. Turner, E. April 15, 1916 Pressure-regulating valves.-Relates to valve apparatus for mixing two or more gases or vapours wherein the two fluids are adustably proportioned and the mixture maintained at a constant pressure. The controlling valve comprises a hollow piston 8 sliding in a casing having inlet ports 2, 3 for the two gases, an outlet port 4, and a return by-pass port 6. To regulate the gas proportions, the valve is turned by a. lever 22 which operates through a spindle 20 engaging a closed socket 19. The pressure of the mixture is adusted by varying the weight 14 which is picked up by the piston valve as it rises. The valve is balanced by the counterweighted lever 16. As the compressor, blower, or the like 5 draws and forces the mixture, the discharge pressure operates through the pipe 25 under the piston valve. If excessive, this pressure raises the valve, restricts the supply at the ports 2, 3, and by-passes some of the gas through the port 6, the port 13 in the valve partition 12, and the port 4 back to the compressor &c. 5. The valve 8 may however be operated by the suction of the compressor, &c., or by the suction and delivery combined.
