ABSTRACT:
In a fluid spring arrangement for a metal forming die assembly of the gas-operated, piston-cylinder type, the surfaces of the piston and cylinder which are in sliding contact are lubricated by lubricant entrained in the pressurized gas directed into the working chamber of the cylinder. The lubricant is contained in an apertured cartridge within the cylinder through which the gas is constrained to flow. A valve plate cooperates with an apertured wall of the cartridge to entrain lubricant in the gas when the flow of gas is into the cylinder and prevent the entrainment of lubricant when the flow of gas is out of the working chamber of the cylinder.
