摘要： A poppet valve in which a poppet is slidable in a valve body and opens or closes a main valve path for pressurized fluid at one end. The pressurized fluid is conveyed to a back pressure chamber at the rear of the poppet either through a reduced flow path or through a valve arrangement between the surfaces of the poppet and a poppet spool slidable within the poppet. Either a control rod or the poppet spool moving relative to the poppet opens a flow path at the side of the back pressure chamber and the flow continues through a hollow in the spool or the control rod to an oil chamber away from the back pressure chamber where it is released to a tank.
