0 operated by or involving the pressure of water or some other liquid:
1 (of a device) operated by water pressure or by pressure from another liquid:
The plane’s hydraulic systems can withstand incredibly high temperatures.
2 a hydraulic machine or tool operates by using power from the pressure of water or another liquid:
They manufacture hydraulic pumps, valves, and motors.
However, alternative energy sectors (electricity and hydraulic), plus the textile sector are the 'winning' sectors here.
Also, the actuator is equipped with two pressure sensors in the hydraulic circuit; they monitor the output torque.
Further improvement was sometimes achieved by trial-and-error adjustment of the valves controlling the oil pressures in the hydraulic system.
Melted paraffin wax was poured over the agar to provide an effective hydraulic seal.
Actuation of the lift and tilt hydraulic cylinders is achieved by specifying a valve position for lift and tilt respectively.
The present day humanoid robots are stiff-legged, have complex structures, and do not use energy restoring element like pneumatic hydraulic cylinders or mechanical springs.
Each hole connected by nylon hydraulic tubing to a ' fluid commutator ', a manifold containing a rotatable, ported centre-body.
The latter may seem somewhat specialized, but is important because hydraulic actuators are critical components of robotic devices that enter hazardous environments.
