Hydraulic accumulators are widely used in mobile systems in bladder, diaphragm and piston formats.  Applications for suspension and ride control have led to an increase in the number of smaller accumulators being mounted directly onto cartridge manifold sub systems. Their many uses include emergency storage, leakage compensation, shock absorption and noise reduction.   While it is always a good idea to consult the manufacturer when integrating an accumulator into a manifold, taking the following parameters into consideration can help you avoid system issues.

Someone recently joked with me that I’ve never created a circuit that didn’t have at least one Logic Valve in it. HydraForce model numbers for these valves begin with the prefixes EP, EPFR and EV. Typically, these valves are piloted-closed, vented-open, or used as pressure compensators or regulators. I use them often because they are versatile, and they have low pressure-rise and pressure-drop characteristics.

On our catalog pages for these valves, we describe them as: “hydraulic directional element, with multifunction potential when used with other directional, pressure, or flow control devices.” Talk about a vague (albeit true) statement. So, to demystify this situation a little, I started to think about all the different ways spool-type logic valves can be used in integrated circuits. I’ve sketched up some generic circuits that show different ways in which we use spool type logic valves:
