A device ( 1 ) for the hydraulic lash adjustment for several identically acting gas-exchange valves per cylinder of a valve train of an internal combustion engine is provided, the device ( 1 ) including a common housing ( 2 ) with directly adjacent pressure pistons ( 3 ) provided corresponding to the number of identically acting gas-exchange valves. Each pressure piston ( 3 ) moves relative to the housing in an axial direction in a separate guide ( 4 ) in the housing ( 2 ), and also has a support ( 6 ) for an at least indirect contact with the corresponding gas-exchange valve on a distal end ( 5 ) away from the housing, and a non-return valve ( 8 ) in the region of a housing bottom ( 7 ) wherein a separate high-pressure chamber ( 9 ) is associated with each pressure piston ( 3 ) in which the non-return valve ( 8 ) opens. The high-pressure chamber ( 9 ) extends axially between the bottom ( 7 ) of the pressure piston ( 3 ) and a base ( 10 ) of the housing ( 2 ), and the pressure pistons ( 3 ) arranged in the common housing ( 2 ) have a common reservoir.
