Abstract
An injection assembly with pressure booster for pressure die-casting machines, which includes a main injection piston (7) that is actuated by a pressurized liquid that is allowed to flow by a check valve (13), and a booster piston (17), which is arranged so that it can slide axially with respect to the main piston (7), wherein the multiplier piston (17) is separated from the check valve (13) and is arranged downstream thereof along the advancement direction of the main injection piston (7).
