Abstract

1475065 Fluid-pressure servomotor systems CAV Ltd 6 May 1974 [15 May 1973] 23004/73 Heading G3P A valve 18 is supplied by a source 14 and regulates a drain outlet 21 to provide a pressure higher than a control pressure by an amount determined by a spring 20 The control pressure may be regulated by a centrifugally actuated valve 11 and the valve 18 may be used to control the supply of fuel to an I.C. engine.
