Controlled by a “push-pull” control but powered by fluid power, the Kobelt 4605 hydraulic servo cylinder allows the user to produce half-a-ton of force with minimal human effort.
This product can be used wherever large forces are needed at fingertip actuation. Possible applications for this unit include waterjet reversing buckets and controlling CP propeller lever mechanisms. As well as controlling mechanical gearboxes and steering systems.
Cylinder 4605 is available in 4”, 6”, and 8” strokes and in either 1/4-28 UNF or 3/8-24 UNF threads on the valve spool. It is fully compatible with Kobelt’s 2000-series Push-Pull control heads and cables.
The 4605 unit consists of two main subunits, the valve and the cylinder. The operating principles of the cylinder are very simple. Pressurized fluid is directed to either end of the cylinder causing it to retract or extend and exert a force on whatever it is connected to. The valve is what is used to control the operation of the cylinder. It takes input from the user via the spool and directs the pressurized fluid where it needs to go to. It will complete the desired action (i.e. extend, retract, or stay in the current position).
See Figure 1 below for a depiction of the components.
