Abstract
17,089. Auld, J. Aug. 14. Lift valves; actuating valves.-To enable a lift valve to be. opened easily it is fitted with a balancing-piston, the pressure on which is controlled by a separate auxiliary valve. In one form, shown in Fig. 1, the piston b is made a. loose fit in the liner c so that fluid pressure admitted at.e leaks past the piston into the chamber a and tends to. hold the valve on its seat. When opening- the main valve, the auxiliary valve g is first opened to connect the chamber d to the outlet f through a passage h and so balance the valve. In a modification, pressure is admitted below a balancing-piston when it is desired to open the main valve.
