Abstract

180,386. Gilkes & Co., Ltd., G., and Thorpe, G. E. T. Jan. 26, 1921. Regulating.-In control gear for hydraulic turbines comprising a deflector 7 and a nozzle spear valve 5, the pressure fluid from the nozzle inlet has direct access to one side of a piston 14 on the spear valve rod 4, and on the other side the inflow is adjusted by a valve 26 and the outflow regulated by a poppet valve 16 bearing on an outlet port in the piston through which this pressure fluid passes along the hollow valve rod 4 into the jet. According to the invention, a dash pot 24 connected to a bell-crank lever 20 with an adjustable tappet 21 bearing on the poppet valve 16 prevents this valve following up the piston too quickly, but allows its quick return: In operation, on a rise of speed occurring, the deflector 7 connected to a governor sleeve 12 immediately masks part of the jet and the linkwork 11, 37, 36, 35 compresses a spring 34 bearing on a lever 33 of the bell-crank lever 20 so that the poppet valve 16 moves forward but only slowly by reason of the dash-pot 24; the outlet behind the piston 14 being therefore closed, the pressure increases and the spear valve 5 moves slowly forward to close the jet and at the same time the deflector 7 moves out of the jet. On a fall of speed, the link-work 'positively rotates the bell-crank lever 20 and the pressure returns the poppet valve 16. A filter 27 is provided for the pressure fluid before it reaches the valve 26.
