machine that takes advantage of the fact that pressure is sorted out equally in all directions possible in a liquid. :)
archimedes' principle
Yes
-your device must use hydraulics to exert a large force, using minimal space. - your hydraulic system must transmit motion smoothly. -you must be able to operate your device with no breakage of parts.
A hydraulic device
A spring device which maintains the spool of a directional control valve in position.
hydraulic ram
A hydraulic pump uses an external mechanical force to pressurize the hydraulic fluid. A hydraulic motor uses the pressurized hydraulic fluid to apply a mechanical force an external machine. See the difference between a pump and a motor.
* EVAD Ebbw Vale and District Development Trust * EVAD Electro-Hydraulic Ventricular Assist Device
It is automatically tensioned by a non-user-adjustable hydraulic device.
a hydraulic system multiplies a force by applying the force to a small surface area.the increase in pressure is then transmitted to another part of a confined fluid, which pushes on a larger surface area
The work done is equal
Leaks are your first clue, and the operations of the device your using it for, slows down or is not as powerful.
