Patent ID: 8479768

Claim:
A directional control valve arrangement, comprising: a directional control valve ( 8 ) including a valve spool ( 22 ); a pressure-medium connection between a pressure passage (P), a discharge passage ( 18 ), and two working passages ( 14 , 16 ), wherein said pressure-medium connection is controllable via said valve spool ( 22 ); a releasable blocking valve ( 10 ) provided in a first working passage ( 14 ), wherein the releasable blocking valve ( 10 ) is arranged between a first section of the first working channel ( 14 ) leading to the valve spool ( 22 ) and a second section of the first working channel ( 14 ) leading to an outer working connection ( 1 ), wherein when the first working channel ( 14 ) is blocked via the valve spool ( 22 ) toward the tank port ( 18 ), the second section of the first working channel ( 14 ) is relieved of pressure; wherein an intermediate space ( 100 ) in the pressure-medium flow path between the blocking valve ( 10 ) and a control edge ( 65 ) of the valve spool ( 22 ) that blocks the working passage ( 14 ) toward the tank port ( 18 ) is provided to accommodate a compression volume from the second section of the first working passage ( 14 ), and wherein the intermediate space ( 100 ) is connectable to the second section of the first working passage ( 14 ) by controlling open the blocking valve ( 10 ) when the discharge passage ( 18 ) is blocked by the control edge ( 65 ).
