hydraulic press

Physics

A device in which a force (F₁) applied to a small piston (A₁) creates a pressure (p), which is transmitted through a fluid to a larger piston (A₂), where it gives rise to a larger force (F₂). This depends on Pascal’s principle that the pressure applied anywhere in an enclosed fluid is transmitted equally in all directions. The principle of the hydraulic press is widely used in jacks, vehicle brakes, presses, and earth-moving machinery, usually with oil as the working fluid.

Hydraulic press.

Chemical Engineering

A device in which forces are transferred by way of pressure in a fluid. A force F₁ is applied over an area a₁ and is transferred to a smaller area a₂ resulting in an increased applied force F₂ such that $F_{2} = F_{1} \times a_{2} / a_{1}$ . Extreme pressures can be obtained using pressure multipliers in which a force applied over a large area is transferred over a very small area thereby intensifying the pressure. This pressure can be intensified further by transfer onto an even smaller area.
