摘要： A method for controlling movement of a piston in a metering device is described. The method comprises supplying a fluid by actuating the metering device's piston, wherein compression or expansion of the fluid causes corresponding temperature variations. The method further comprises superposing a corrective movement onto the piston movement, with the corrective movement at least partly compensating for at least one of thermal expansion and contraction of the fluid induced by the temperature variations. In one embodiment, the corrective movement imposed onto the piston movement comprises two components: a reduction (74) of the compression jump (73), and a subsequent increase (75) of the piston's forward displacement rate (71) during a period (76) of time (72).
