Abstract
A valve housing includes a cylindrical valve bore with a high pressure inlet, a low pressure inlet and a discharge outlet. A first flushing valve spool is arranged elastically pre-stressed within the valve bore for enabling a fluid connection between the low pressure inlet and the discharge outlet. A shuttle valve spool is arranged elastically pre-stressed within the valve bore for enabling the fluid connection between the low pressure inlet and the discharge outlet. The first flushing valve spool is moveable into an open position if the fluid pressure at the low pressure inlet exceeds a first threshold value, and the shuttle valve spool is moveable into an open position for connecting the low pressure inlet with the discharge outlet, if the pressure difference between the high pressure inlet and the low pressure inlet exceeds a second threshold value.
