Abstract
A sliding door system includes a door frame and a sliding door leaf that can move relative thereto. A catch is arranged either on the door frame or on the sliding door leaf, which can be coupled to a drive element of a feed device arranged on the respective other component. The feed device has a spring energy store and a cylinder-piston unit. The cylinder-piston unit has a piston that separates a displacement chamber from a compensation chamber. A passage cross-section between the displacement chamber and the compensation chamber can be changed in a load-dependent manner by a piston disk that can be applied at a piston end side. The tension force of the tension spring of a minimal effective length is between 1.5 and 3.5 times the total static friction force of the sliding door leaf and the resistance of the cylinder-piston unit at the maximum passage cross-section.
