Question 1 a-Single acting cylinder 1 I need a force of 300 kN for the extension stroke. In this single acting cylinder the spring force of the pre-loaded spring varies from 2.4 to 7.2 kN. Max. system pressure (for the hoses etc.) is 500 bar. . . The diameter of the rod is 5 cm, the piston diameter is 10 cm. What system (gauge) pressure do I need at the blind end of the cylinder? Is this ok (max system pressure)? What is the max. back-pressure on the return line (max. gauge pressure at the cylinder port on the blind end) we can tolerate to make sure this cylinder will return? Will the (return) flow start quickly? Fluid from Pump Cylinder Spring Rod End Blind End Piston Drain Rod Extension Retraction
