Abstract

The invention relates to a cylinder accumulator with a floating piston (6), subdividing the cylinder space into an oil space (4) and a gas space (5), in a hydraulic circuit. A control rod (14) projecting axially into the gas space (5) is arranged in an axially movable manner at the cylinder lid (3) on the gas-space side, which control rod (14) acts through the piston (6) on a control valve (18) arranged in the cylinder lid (3) on the gas-space side. Crossing a part (3a) of the cylinder lid (3) projecting from the cylinder lid (3) is an oil passage (17a, 17b), in which the control valve (18) is arranged in the area of the cylinder axis and the inlet side (17a) of which is connected by a bypass pipeline (19), bridging the accumulator, to the pipeline (8), leading into the oil space (4), for the charging-oil flow. A distance tube (23) coaxially surrounding the control rod (14) is arranged on the inside of the cylinder lid (3) on the gas-space side. The distance tube (23) accommodates a spring arrangement which is supported on an intermediate base (25) arranged in the distance tube (23) and acts via an abutment (27) against the piston (6) on the control rod (14). <IMAGE>
