Electronic oscillator for a hydraulic flow divider

It is a common fact that sometimes in hydraulic actuation it is necessary to divide the flow in order to synchronize the movement of various mechanisms. In that case it is used a hydraulic flow divider that can be mechanically or electronically driven. Further we will refer only to the electronically driven hydraulic flow divider. Having a simple construction, the flow divider doesn't need a supplementary supply pump and uses a single rod that glides to the left or to the right according to the frequency of the driving signal.
