Abstract
A device for adjusting the quantity of molten metal used in pressure casting has a pump pumping molten metal up from a supply container to a pressure chamber and to a level-determining tank having an adjustable overflow. Hydrostatic pressure balances the levels in the level-determining tank and the pressure chamber so that adjusting the overflow also adjusts the level of metal in the pressure chamber.
