Title: Fluid control valves
Inventor: GUY KENNETH THEODORE
IPC: F16K31/122
Filed: 1965-07-08
Abstract: 1,136,093. Valves. ROTAX Ltd. 30 Aug., 1966 [8 July, 1965], No. 28943/65. Heading F2V. [Also in Division G3] A valve controlling the flow from an inlet 12, Fig. 1, to an outlet 13 comprises a valve closure 18 carried by a piston 17 which is subjected to the fluid pressure in chambers 19, 20. The chamber 19 is connected by conduit 22 to the downstream pressure while the chamber 20 has a constant pressure regulated by a valve 24. The valve 18 is thus adjusted with changes in downstream pressure to keep this pressure constant. A second valve 29 is connected to a piston 25 and the chambers 26, 27 on opposite sides of the piston are connected by conduits 32, 33 to control valves 34, 35, Fig. 2, which under normal conditions are in the positions shown whereby the chamber 26 is connected to a pressure supply 39 and the chamber 27 to exhaust through ports 38 so that the valve 29 is open. A piston 50 is loaded by a spring 58 against downstream pressure applied through conduit 51. If the valve 18 sticks say or the downstream pressure rises above a predetermined value for any reason, the pressure causes the piston 50 to depress a plate 45 and actuate the valves 34, 35 to cause closure of the valve 29. Downward movement of the piston 50 to actuate the valves rocks a locking device until a rod 62 engages a notch 65 to hold the piston 50 in its lowermost position. To release the piston 50, a valve 53 is actuated to lower a second piston 49 which carries a spring 57 which, when the valve 53 is again actuated to cause the piston 49 to rise, rocks the lock to release the pin 62 from the notch 65. When the valve is operating normally, the valve 29 may be closed by actuation of the pilot valve 53 when the combined pressures on the pistons 50, 49 actuate the valves 34, 35.

Filed: 1960-08-25
Abstract: 954,215. Thermal regenerators. DIDIERWERKE A.G. Aug. 25, 1960, No. 29320/60. Heading F4K. An arrangement for changing over the operating conditions in a thermal regenerator such as a coke oven regenerator, comprises hydraulic actuators 8a, 8b, 8c &c. which actuate members such as gas valves, waste heat and air valves or dampers and are operated in sequence by control members 9 such that each control element is brought into operation by another or the previous actuator in the circuit. The hydraulic actuators are preferably of the double-acting piston type. Operation of the circuit shown is initiated by movement of a rotary valve member 6 whereupon fluid such as oil under pressure from the reservoir 1 passes via lines 7 and 7a to the first actuator 8a, the piston in which moves upwardly (direction 10) and operates control member 9a to permit pressure fluid to flow through line 7b to the next actuator 8b. Consequent movement of the piston in actuator 8b (direction 11) operates control element 9b, thus allowing pressure fluid to operate actuator 8c. Movement of the piston in actuator 8c actuates a limit switch 13. On reversal of the regenerator valves &c. becoming necessary, the rotary valve element 6 is operated so that pressure fluid flows first to actuator 8c and the system then functions in reverse until all the actuators have been operated and the piston of actuator 8a makes contact with limit switch 13. Provision is made for manual operation of fluid pressurizing means in the event of an electrical failure. 13a are limit switches which operate to fix the control members 9 in position only when there is a shortage of gas or an electrical failure occurs.
