Abstract

The invention concerns an equaliser for the forced closure of a suction valve in die-casting moulds. It consists of an external body or casing (11), a central thrust piston (16) guided axially on a guide head (17) and a multiplicity of Belleville washers (18) placed concentrically between piston and body. The Belleville washers (18') are set out in groups on several parallel levels defined by spacers, and each group of Belleville washers lies axially with one part on a collar (19) around the thrust piston and the other part on a support washer (20) in the said body. <IMAGE>
