A hydraulic actuator is a device aimed to enable and assist the automatic opening or closing of a valve. It automates the whole steering process minimizing the human interaction with the valve package.
Hydraulic cylinders add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds and reduce considerably the physical effort necessary to turn the wheels when the vehicle is stopped or moving slowly.
A hydraulic actuator uses its hydraulic power to smooth the mechanical functioning of the machine, giving an optimal output in terms of linear, rotatory or oscillatory motion.
