Can anybody direct me on reading on regen circuit. I need to understand when an why is used.

Thanks

RE: Regenrative circuit

Read this pdf from SUN hydraulics.....

quote from SUN document..
"Regenerative circuits allow a cylinder to be advanced more rapidly than it could be with pump flow alone. To achieve this, oil from the rod end of a cylinder is added to the pump flow to the blind end, increasing the rate of advance.
NOTE: Regeneration circuits apply only to single rod cylinders in the extended direction."



When a force from gravity or inertia extends the cylinder, the rod side might drain faster than the pump can fill the void on the capped side, and capped side will be subject to cavitation. By linking the flow from the rod side over to the capped side, pump only need to fill the volume difference, which is equal to the volume of the piston rod.
Such flow link system is called regeneration of flow.
There are a few ways to regenerate flow, the control valve spool can be designed to be regenerative, and there are inline valves (SUN valves), that can regenerate flow.

Thanks Mr Akkamaan,

Is it basically like having an hole on the piston cap?
It will open when the rod extend and close when it will rectract.

Thanks
 

RE: Regenrative circuit

No, it's like having a hole in the piston.  It is open when the piston extends and is closed when the piston retracts.

When regenerating, the piston active area is that of the piston rod.

Hi Faq,

The link does not work..can you try to post it again or
give some other direction on ho to get that document?
