| 1. A vibration damper comprising:
a cylinder filled with damping medium;
a container surrounding said cylinder and forming a compensating space between the container and the cylinder;
an endwall fixed to an end of the container and enclosing an end of the cylinder and an end of the compensating space, said
endwall having a first filling channel connected to said compensating space and a closing element in the first filling channel,
said first filling channel having a shoulder facing said compensating space;
a spring which loads the closing element against the shoulder;
a piston rod received through said endwall, the piston rod being connected to a piston which is movable in the cylinder;
a pressure container in said compensating space; and
an adapter having first and second ends and a second filling channel extending from said first end to said second end, said
adapter having an upper part proximate said first end fixed to said endwall and a connecting part proximate said second end
connected to said pressure container such that said pressure container is connected to said end wall only by said adapter,
said second filling channel of said adapter having a first open end which communicates with said first filling channel in
said endwall, and a second open end inside said pressure container,
wherein the upper part comprises flats for rotating the adaptor with respect to the endwall, whereby the pressure container
can be oriented in the compensating space.
