    摘要: In a solar generator, comprising a reflector and an electrohydraulic sun-position tracking device with at least one hydraulic cylinder and a hydraulic control seat valve, the reflector can be guided via the control seat valve to follow in synchronism with the course of the sun continuously and uninterruptedly. The control seat valve for regulating a pressure medium flow permanently supplied to the hydraulic cylinder comprises a seat surface and a sealing surface permanently pressed against each other with variable contact pressure, with which the pressure medium flow can be generated as controlled leakage. The sealing surface is made of a material that can be deformed by contact pressure. In the control seat valve, the controlled leakage is set in a control position at least substantially without lifting movement exclusively by the relative material deformation of the sealing surface on the seat surface, which deformation is set via the contact pressure.

    摘要: An electrohydraulic control device for an adjustable hydraulic pump system includes a valve device, an electronic control unit and a first fluid sensor. The valve device includes a pressure inlet, a tank outlet and a first electromagnetically actuated valve. An outlet pressure of the first adjustable hydraulic pump system is applied to the pressure inlet. The first fluid sensor detects an actual value of a fluid parameter of the first adjustable hydraulic pump system and transmits it to the electronic control unit. The electronic control unit includes computer-based modeling of the dynamics of the first adjustable hydraulic pump system, and actuates the first electromagnetically actuated valve based on the actual value of the fluid parameter and the computer-based modeling.
