摘要： An injection apparatus for a hot-chamber die-cast machine including a cylindrical sleeve; a plunger body slidingly movably disposed in the sleeve and having a circumferential groove on an outer cylindrical surface and passages extending from a pressurizing face to the groove. Divided seal rings fit loosely in the groove of the plunger body in such a manner that the divided rings are urged radially outwardly by the pressure of the molten metal in the sleeve through the passages when the plunger body is moved. The divided rings satisfy the following conditions:t.sup.3 .ltoreq.4.5.times.10.sup.2 (mm).times.D.sup.2 .times.P/Ewhere t: thickness (mm) of the divided rings, E: Young's modulus (Pa) of the divided rings, D: inner diameter (mm) of the sleeve, and P: pressure (Pa) which should be exerted onto the molten metal when injected.

摘要： The apparatus for filtering scraps of light metal for regeneration thereof comprises an upper vessel having heating means for maintaining the scraps, charged therein for the filtration thereof, at a predetermined temperature so as to melt the same or for maintaining molten metal, supplied therein after having been molten, at the predetermined temperature, a lower vessel having heating means, filtering means interposed between the upper and lower vessels, temperature controlling means for both the heating means, pressurizing means connected to the upper vessel and/or depressurizing means connected to the lower vessel, and a lifting/lowering device for the upper vessel and/or a transporting device for the lower vessel. The apparatus may further comprise an inner vessel for receiving molten metal having been passed through the filter means, which is freely removably arranged in the lower vessel.
