The stems that support wicket gates of hydraulic machines such as pump turbines are stablized against undesired oscillation or other vibration by applying a transverse hydraulic force against each stem to push it against one side of a supporting bushi...
In an improved hydraulic device the leakage of fluid between a rotor and a first one of a pair of end plates is prevented by a metal-to-metal seal between the rotor and end plate. To maintain the seal, the rotor and end plate are urged together under ...
