A pressurized fluid, typically air, or a centrifugal wheel is used to propel the blasting material (often called the media).

The technique, which involves cracking open rock seams with pressurized fluids, is only just starting to be used in Europe.

This is usually achieved by the introduction of pressurized fluid through the particulate medium.

The pressurized fluid pushes a piston down in its cylinder, recycling some of the energy to turn the vehicle's wheels.

The shaft spins within a cylinder of pressurized fluid, without mechanical contact.

Once they reached the fault, the pressurized fluids did exactly what they're meant to do: force open existing fractures.

Hydraulic cylinders get their power from pressurized hydraulic fluid, which is typically oil.

When an erection is desired, the man uses a pump to fill the cylinders with pressurized fluid.

This will cause pressurized fluid in the formation to flow into the wellbore and make its way to the surface.

A hydraulic motor is one that derives its power from a pressurized fluid.
