Claim Text:
1. An injection assembly for a molding machine, comprising: an injection piston; a drive device for moving the injection piston; and a force storage means, wherein the force storage means comprises a spring device, and connects the drive device to the injection piston, the molding machine includes a molding tool, and injection material is injected by the injection piston into a cavity of the molding tool of the molding machine at a first injection pressure which is set by a control or regulating unit, the spring device is of a stiffness which substantially corresponds to a counteracting force acting on the injection piston at the first injection pressure of the injection material, and at an increased injection pressure which is above the first injection pressure, the injection piston is moveable relative to the drive device against the stiffness of the spring device and with elastic deformation of the spring device.
