Abstract

PURPOSE:To let the pressure medium substitution of a pressure cylinder requiring holding of pressure-contact for a long time by communicating the push side chamber and pull side chamber of the pressure-contact cylinder by way of a pressure medium sustituting mechanism which makes open operation when the pressure of the push side chamber becomes more than a fixed value. CONSTITUTION:When an electromagnetic changeover valve 12 is set by a pressure- contact signal, the pressure oil having been accumulated in an accumulator 11 is supplied through the valve 12 to the pressing chamber 2 of a pressure-contact cylinder 4, causing a piston 1 to move leftward and stop when it contacts the pressure- contact target 14. At the same time, the pressure oil in the pull side chamber 3 is discharged through the changeover valve 12 to a discharge oil tank 15. When the pressure contacting is started, the circuit pressure of the pressing chamber 2 rises and the pressure oil thereof operates a sequence valve 19 and passes therethrough, thence it opens a pilot valve 18, through which a small amount of the pressure oil flows via orifice 17 into the pull side chamber 3. The pressure oil then recirculates into the discharge oil tank 15 through the electromagnetic changeover valve 12.
