H Type Hydraulic Press Machine
The hydraulic press depends onPascal's principle-thepressurethroughout a closed system is constant. One part of the system is apistonacting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force. Only small-diametertubing(which more easily resists pressure) is needed if the pump is separated from the press cylinder.
