The present invention relates to a dual-stage pump for a hydraulic system with a housing, a high and low-pressure pump element, a common pressure outlet and a switching valve that is arranged between a tank connection and the low-pressure pump element. The switching valve has a spring element and a piston being movable against a force of the spring element relative to the housing and having a closing member that can be lifted from a valve seat by a control pressure that is tapped on the pressure outlet and applied in a control pressure chamber. On the one hand, the invention is characterized in that the switching valve comprises a tappet that is movable relative to the housing and configured to move the piston and arranged between the control pressure chamber and the piston and has a smaller effective diameter than the piston. On the other hand, the invention is characterized in that the dual-stage pump comprises at least one valve that can be screwed into the housing, wherein a cutting edge of the valve is sealingly cut into the housing.
In a hydraulic drive of a tool piston in a cylinder first and second flat contact areas each are contiguous, when moving into and in the open position of the valve member between the detent element and the valve member, wherein a pressure-limiting valve that can be loaded with the pressure in the cylinder from a closed position to an open position and a detent element loaded by a spring in the locking direction to positively hold a neck of a valve member of the pressure-limiting valve are arranged in the open position, wherein the detent element at least via the tool piston at its return to a released position can be moved and, when moving the valve member to the open position of the pressure-limiting valve, non-positively acts on the valve member.

Pressure-controlled 2-way flow control valve for hydraulic applications and valve assembly comprising such a 2-way flow control valve
The present disclosure provides, in a first aspect, a pressure-controlled 2-way flow control valve for hydraulic applications, wherein the 2-way flow control valve has applied thereto a first pressure signal in the closing direction of the 2-way flow control valve by means of a first output-side tapping and a second pressure signal in the opening direction by means of an LS pressure reporting duct. A pressure signal corrupting the first or second pressure signal is applied to the 2-way flow control valve in the closing or opening direction by means of a second tapping which is effective at least over part of the control stroke of the 2-way flow control valve.

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.
