Not necessarily. It would depend on the total amount of flow delivered to the piston side. If the hose was already at its flow limit without regeneration, then yes, it is possible that the regenerated flow from the rod side could make the flow exceed the rated amount.
Great video! Does the ratio of the cylinder need to be 2:1? I have a 4” bore 1.75” rod cylinder for a log splitter that I wanted to add a regenerative circuit to but read that it should be a 2:1 ratio for the circuit to work, is this the case?
Thank you for your comment and question! No, the ratio need not necessarily be 2:1. Naturally, the greater the difference in surface area, the more pronounced the effect will be, but regenerative flow works with any cylinder (except a double rod cylinder with both rods the same size).

Hello Jack.. good evening...I wanted to undergo your courses but I believe the website appears shut down after covid. Can you help me ? Are you having any other course from any other source
Hi Rambobidu. Thank you for your question! I don't suppose it has much to do with regenerative flow, but perhaps I can answer it to your satisfaction. The valve you are speaking of is called a logic valve. It is typically piloted by a 3-way directional valve which, depending upon its condition, will either apply or release pilot pressure at the top of the valve piston. The logic valve has three ports, each acting upon a different surface area. The top surface area is equal to the sum of the surface area of the side and the surface area at the bottom. Since this makes the top surface area the largest of the three, more force will be generated to close the valve than to open it, so long as the pilot pressure is equal to or greater than the pressure in the other two ports. The valve will therefore remain closed if pilot pressure is applied. If pilot pressure is released, the valve will open so long as the pressure at one of the lower ports is sufficient to overcome the tension of the spring. The spring is of a somewhat negligible value - enough to hold the valve closed when there is no hydraulic pressure in the system at all. This logic valve will thus function very similarly to a pilot-to-close check valve. Hope this helps!
Dear sir How can I send you my circuit diagram for my doubt clearance.i have some doubts related to axial piston pump and power limiting valve. My whole equipment is of REXROTH.please help me ? I Will be obliged to you sir
even the regenerative cycle cannot explain itself like you did thanks :)
Such a well- done explanation video. Thanks Jack!
Thank you for your kind comment, John!
Excellent explanation Jack, thanks for doing this video! This will help SOOO many people.
Thanks!
Jack,
Please keep up the good work! This is awesome!
Thank you very much!
Understood very clearly,thanks
Thank you very much for your kind comment!
thank you .. that was a good explanation .. keep up the good work man !
Thank you very much for your kind comment!
I never could work out how my log splitter with single-stage pump has two extend speeds, but I think this video just explained it.
Nice Explanation Man....
Thank you, Rajat!
Excellent work
Thank you very much, Steven!
thank you
Very nicely explained. Thanks for upload ing this video. I'm searching for 400 mm bore cylinder using pcm circuit. Please help.
Am I mistake or would having a slightly larger hose to the piston side be required to maximize the efficiency of a regen circuit?
Not necessarily. It would depend on the total amount of flow delivered to the piston side. If the hose was already at its flow limit without regeneration, then yes, it is possible that the regenerated flow from the rod side could make the flow exceed the rated amount.

Perfect. I am interested in your online training. I just wanted know if there is any discount during the crisis.

i love how to say this .. great man very nice style :D
Thank you, Yousef!

Kindly upload some video about how to identify whether my axial piston pump needs replacement.
This one should help! ruclips.net/video/yh8B-RNzdSY/видео.html
