Abstract
A hydraulic valve includes a valve housing, a valve cone, a spring housing, a check valve, a first hydraulic connection and a second hydraulic connection. The valve housing has a valve seat and the valve cone is movable in the valve housing between a closed position and an open position. In the closed position, the valve cone is in contact with the valve seat and blocks a first flow path between the first and the second hydraulic connection. In the open position, the valve cone is lifted off the valve seat and the first flow path is opened. A spring element is disposed in the spring housing, which biases the valve cone into the closed position. The check valve is disposed in the valve cone and opens a second flow path from the second hydraulic connection to the first hydraulic connection when pressure is applied to the second hydraulic connection.
