< Mentor Note -- thread moved to HH from the technical engineering forums, so no HH Template is shown > Hey. We are a group of 4 students, working with a project. The focus is directed towards the supply of hydraulic fluid. Four different piston cylinders subjected to different gradient pressures needs to be supplied with lubrication, but the volumeflow needs to be the same at each supplyline. We are not sure how to manage to achieve same volumeflow in each supplyline when the pressure gradients are different. We have been thinking about installing a pump for each supply line, but that will take to much place. Everithing needs to be minimized. Do you guys have some ideas? Answers will be much appreciated!
