An “unloading” system is used to divert pump flow to a tank during part of the operational cycle to reduce power demand. This is done…

Closed circuits are widely employed in vehicles performing running, circling or HST (Hydro Static Transmission: no shift change for speed change) functions. One of the…

This figure is an example of a motor that turns both directions. With the solenoid valve in position 1, the hydraulic motor turns right. After…

This circuit intensifies pressure by using the difference between cap and head area in cylinders. In the following figure, the solenoid valve for adding pressure…

This circuit detects the position of two cylinders and uses two servo valves to control the amount of working fluid required to adjust synchronization errors.…

This circuit realizes a very accurate synchronized motion via combined synchronizing cylinders. But, sometimes, spacing becomes an issue because it requires the volume of all…

With the shafts combined, these motors can displace the same amount of working fluid to and from each cylinder. The accuracy of the amount of…

This circuit utilizes the flow divider specialized for synchronization.

In this circuit, the flow control valve controls fluid flowing in and out of the cylinders. Generally, a high accuracy valve is employed.

This circuit realizes a synchronized motion by mechanically combined cylinder rods. In the following figure, the relationship between the two main cylinders and two other…
