Use cases in automation
A hydraulic temperature control works without auxiliary power. The principle is based upon the thermodynamic change of volume due to changes in temperature. A vessel filled with hydraulic oil produces an increasing pressure when temperature is rising. The pressure is used to move a piston, connected to a valve.
Use cases for fluid power
- The tools of digging machines are moved by hydraulic power.
- Heavy hatches can be locked by hydraulics.
- Brakes in cars are usually hydraulic.
