Abstract

The valve block has an inlet side high-pressure valve connected to a HP feed passage, and an inlet side low-pressure valve connected to a LP feed passage. Both valves on the outlet side are connected to a common working channel and each have a switchable valve component by which the connection between the respective corresponding valve inlet and valve outlet is selectively shut off or opened. The connection between the outlet of the LP valve and working channel is check valve free.
