摘要 |
<p>A pilot-controlled pressure limiting valve with a feeding function for pressure medium to be replenished comprises a main control spool movable between a pressure chamber and a high pressure inlet and being formed with a control edge to control communication between the inlet and a low pressure outlet; an annular piston slidably surrounds the main spool and in the closing position of the spool rests on a stationary abutment in the range of the low pressure outlet; the other face of the annular piston cooperates with a stop flange on the main spool so that when pressure medium is fed into the low pressure outlet the annular piston engages the stop flange and moves the main spool in opening direction so as to establish communication between the outlet and the inlet.</p> |
