Yes, the valve can and does control the flow across the orifice. Sorry but I beg to differ. I guess it would be possible to use something similar in the PLC? No, both compensators are working but they are controlling the maximum cut-off pressure and torque limit pressure not the pump flow. If the flow is dynamically controlled, then power control can be achieved.

You probably know very well how a pressure relief on a LS line work.


View Contact Call Seller Now. By changing the setting on the proportional relief valve, the pressure drop across the orifice will change and so the pump will change its flow to compensate.

This is where the flow control works. The LAXDS controller has an additional relief that is attached to the pump servo piston to give constant a1vso or constant torque. Without such an orifice the small pressure relief valve could become saturated and loose it’s function.


You can see that the pump load sense compensator is looking at pressures on either side of the orifice. A10VSO Variable displacement pump power control You keep saying that the proportional relief valve is to limit the pressure.

The Eng-Tips staff will check this out and take appropriate action. It would also help to know the stand by pressure of the pump Adrian RE: Piston Pumps in Navi Mumbai.

Bosch Rexroth Axial Piston Variable Pumps Type A10VSO series 31

Again, my question is how is it happening? Piston Pumps in Mumbai. Power and torque are both a function of pressure x flow rate displacement. Deactivating this cookie would stop permitting the orders. However the circuit diagram describes a power limiting pump with proportional control of the cut-off pressure ie. Number of Employees 11 to 25 People. The flow can be steplessly changed by adjusting the swashplate. Why is there an LS-spool to start with, why not just a pressure compensator spool?

I personally have nothing more to add, it looks like it works in a particular way,,but I have bee doing this long enough to know that I could be completely wrong. We have several hundred regular clients from both the public and private sectors.

Call Send a quick message. To see if there is a power limiting valve attached to the servo piston. I found a document of Parker, explaining the same load sense control in each stage. Of course the orifice is there to limit the flow as Jacc rightly says.


Only when the final squeeze is required does EV3 energise which leads me to think that its working stroke is relatively short and so power limiting would not be a big advantage.

Red Flag This Post Please let us know here why this post is inappropriate. The delta pressure at the compensator will be the same as the pressure drop across the orifice. It has two drainage ports on the housing, and superior suction performance. The pressure relief valve designed on the pump rate decrease piston is it not a representation of a power control?

How does the pump a10vsoo is flow level. It’s easy to join and it’s free. The way pump pressure and flow control systems work are not similar, they are fundamentally different.

Look at the orifice Could you give me details on this phenomenon? Statistic cookies help website owners to understand how visitors interact with websites by collecting and reporting information anonymously.

I am glad to help I am glad that the help has been worthwhile.

Actually, I’m in England. It would also help to know the stand by pressure of the pump Adrian.
