  • Fluid pressure relay and output booster
    Patent number: 4151856
    Abstract: A primary element is connected to a control element of a first fluid pressure relay to move the element to positions at which pressure fluid outputs of relatively small volumes will be generated to represent the element positions. The pressure fluid outputs of the first relay are directed to the input of a second relay which generates pressure values for pressure fluid which are proportional to the first relay outputs in, and at, relatively larger volumes of the pressure fluid.
