Abstract

Compression device consists of a piston accumulator with an additional gas cylinder, a pump and a distributor. Continuous control is effected by the overflowing of pressure fluid from the hydraulic circuit and the metal casting machine via a valve into the additional gas cylinder, or from the latter via a valve into the hydraulic circuit of the machine.
