For a hydraulic device for supplying at least one load (30) with hydraulic medium on an injection molding machine for processing plastics, a temperature-control device for the temperature control of the hydraulic medium by means of a temperature-control medium is provided, said temperature-control device having a cooling line (15). The hydraulic medium is pumped to the load through at least one hydraulic line (12, 13) by means of a hydraulic pump (10), which can be temperature-controlled by the temperature-controlled hydraulic medium or by the temperature-control medium. A servomotor (20) for the hydraulic pump (10) is connected to the hydraulic pump (10). The hydraulic line (12') containing the temperature-controlled hydraulic medium and/or the cooling line (15) containing the temperature-control medium is led to said servomotor. Because the hydraulic line (12) and/or the cooling line (15) forms a cooling jacket for the hydraulic pump (10), favorable energy optimization is created for the temperature control of the hydraulic device. |
