Hydraulic system, comprises at least two users, at least two adjustment pumps, at least one actuation valve, and a pressure storage unit. A hydraulic system, esp for an injection moulding machine, comprises at least two users, at least two adjustment pumps (1,2), and at least one actuation valve with which the pumps can be operated. At least one user can be supplied with the outlet pressure from at least two adjustment pumps. The latter are electrohydraulic control pumps, and the actual control valve of a primary pump serves as the threshold valve of a secondary pump. A pressure storage unit is associated with one of the users, and the adjustment motors are located on each side of an electric motor. |
