Title: Hosing apparatus

Filed: 1956-11-12
Abstract: 824,965. Cleaning tanks. STRAHMAN VALVES Inc. Nov. 12,1956 [Nov. 14, 1955 No. 34496/56. Class 138(1). [Also in Groups XXVIII and XXIX] Hosing apparatus, in which steam and cold water are mixed and the resultant hot water is delivered to a length of hose provided with a self-closing nozzle at its discharge end, is arranged to maintain the hose filled with water. Water entering past a non-return valve 7a to inlet 12 passes round a loose fitting valve 41 to passage 15 until the pressure is sufficient to move the valve 41 to the left when water flows freely through ports 44. As the valve 41 moves to the left it engages the valve stem 29 and moves this stem to the left against the force of spring 34 to open the valve 22 which allows steam entering past non-return valve 6a and inlet 11 to pass to the steam passage 14. The steam and water rise in chamber 17 and the resultant hot water passes to the hose 4. If, for any reason, the supply of water ceases or the pressure is reduced sufficiently, the spring 34 will cause the stem valve 22 to close and shut off the steam supply to the passage 14. The closing of the valve 22 causes a movement of the valve 41 to close the ports 44, but owing to the loose fit of the valve a small flow of water can pass into the hose 4. Hand control valves are mounted in the steam and water supply lines and the water line may be provided with a small flow by-pass so that, in effect, the water valve cannot be closed. Specification 732,516 [Group XXIX] is referred to.

A tar-stage hydraulic amplifier valve assembly has a first stage comprising a first valve closure member 3 movable with respect to fluid supply and exhaust ports 5, 8 in a housing 1 and a second valve closure member 2 movable with respect to at least one control port 9a in the first valve for controlling fluid flow through the control point to the second valve stage of the assembly, the first and second valve members being coupled by drive means 18, 20 carried thereby for moving the second valve member in response to a control signal, the second stage including feed-back means responsive to pressure variations produced in the second stage by said fluid flow for moving the first valve member with respect to the housing ports to cut-off said flow. Electrical input signals from e.g. a gyro compass, selsyn motor or potentiometer are applied to the terminals 22 to energize the two solenoids 18 carried by the sleeve valve 3 and displace an armature 20 against centralizing springs 21, 26 to move a control piston valve 2 allowing pressure fluid supplied from a port 5 or exhausted through a port 8 to act in a conduit 9 on the end of a piston valve 4. Movement of the valve 4 against a piston 16 hydraulically loaded from the port 5, laps the sleeve ports 7, 15 with the piston valve 2 through a follow-up lever 25. The valve 4 controls the supply and exhaust of fluid to a piston 14. The outside surface of the sleeve 3 may control supply and exhaust piston 14 in which case the parts 4, 16, 25 are dispensed with and feedback achieved by leading the pressure at 9a on to the end face of the sleeve 3 to counteract the fluid pressure force on the other face at 6. A potentiometer coupled to piston 14 may be used to cancel the input signal and restore valve 2 to its neutral position.
