Three=phase pressure diecasting system - has second and third phase passages connected to common high-pressure accumulator

摘要

The pressure-diecasting machine has a three-phase system, the pressure section comprising a cylinder with piston preceded by a compressor cylinder with multiplicator piston. To give constant pressure ratio, the passages for the medium under pressure for the second and third operating phases are connected to a common high-pressure accumulator. The latter is equipped with two separate quantity-regulating devices controlled by solenoid valves.
