Abstract: 598,566. Valves. HOBSON (AIRCRAFT & MOTOR) COMPONENTS, Ltd., H. M., and GREENLAND, L. S. May 22, 1945, No. 12812. [Class 135] A fuel distributing valve for combustion turbine engines comprises a piston valve 42 movable in a cylinder 30 against a spring 58 by the fuel inlet pressure, the cylinder being formed with radial holes 54 which lead through calibrated restricting passages 57 to the several delivery nozzles, and the disposition of the holes or the shape of the valve head or both being so formed that the effective areas of the holes when partly obstructed serve to counteract differences in hydraulic head at the delivery nozzles and tend to equalize the rate of flow through them when the fuel pressure falls below a given value. At higher pressures the holes 54 are unobstructed.. The holes may be arranged at different heights or the end of the valve may have a continuous oblique edge but, as shown, the holes 54 are all at the same height and the lower end of the valve is formed with eleven stopped lands 61 ... 71, Fig. 3, corresponding to eleven circularly arranged delivery pipes 33. The lands are separated by longitudinal slots 60 to facilitate grinding. The holes corresponding to the nozzles with the greatest hydraulic head are the ones least obstructed by the lands. The valve is arranged in a casing comprising two parts 22, 23 secured together and mounted in a panel 25 by bolts 24. A set screw 43 in a slot 44 prevents the valve 42 from rotating. The compression of the spring 58 may be adjusted by a screw 59. A passage 72 conveys any leakage past the piston 42, when it is not pressed against the surface 74 by the full fuel pressure, to one of the delivery pipes 33. Fuel from the supply pipe 46 passes a filter 47 and a check valve 49 on its way to the valve 42. For starting the engine with the valve 49 closed, fuel is delivered from the supply pipe 46 through a branch pipe 52. Specification 598,568 is referred to.
