That '70s show

IN THE FACE OF SOARING FUEL COSTS, MANY OEMs ARE HAVING TO RETHINK THEIR OLD WORK FUNCTION DESIGNS FOR PUMP-UNLOADING SOLUTIONS. HERE'S A FEW HINTS TO ENSURE OPTIMUM EFFICIENCY. Remember when gas was US$0.50 (?0.33) per gallon? It was wonderful; everyone around the globe drove V8s, and no one thought anything of it. Today, the economies of energy are very different. Oil prices are hovering around US$100 a barrel, forcing engineers to increasingly consider fuel conservation when designing new machines. So put a little thought into your hydraulic circuit and you can achieve some pretty considerable fuel savings. To that end, here are a couple of incorrect methods that you should avoid, as well as a few great ways to unload your hydraulic circuit, so that when you're not using the hydraulics, you won't burn through fuel like it's 1974!
