摘要
A new construction of the relief valve is presented with pilot G-pi bridghydraulic resistances network. The design theory of G-pi bridge relief valve is studied and theformulas for designing the relief valve with zero static pressure override are obtained. The staticperformances of the relief valve are experimentally investigated. The theoretical and experimentalresults show that the static pressure override of the developed relief valve can be zero, i.e. whenthe overflow increases the control pressure is kept constant.
