Claim 0:
1. A sliding door system (10), comprising:
a door frame (11);
a sliding door leaf (12) that can move relative to the door frame (11) between an open end position and a closed end position along a door guide rail (15);
a catch (21), arranged either on the door frame (11) or on the sliding door leaf (12);
a drive element (41) of a feed device (30), the drive element (41) being arranged on the door frame (11) if the catch is arranged on the sliding door leaf (12) and the drive element (41) being arranged on the sliding door leaf (12) if the catch is arranged on the door frame (11),
wherein the catch (21) can be coupled to the drive element (41) in a partial stroke range of the sliding door leaf (12) adjacent to one of the open end position or the closed end position, so that the feed device (30) moves the sliding door leaf (12) relative to the door frame (11) into the respective open end position or closed end position,
wherein the feed device (30) has
an acceleration device formed as a tension spring (101) and
a deceleration device (51) formed as a cylinder-piston unit (51),

wherein the cylinder-piston unit (51) has a piston (71) that can move relative to a cylinder (54) and separates a displacement chamber (61) from a compensation chamber (62), and
wherein a passage cross-section between the displacement chamber (61) and the compensation chamber (62) can be changed in a load-dependent manner by a piston disk (91) that can be applied against a piston end side (73) on a displacement chamber side,
wherein a minimum passage cross-section is between 0.5 percent and 4 percent of an internal cross-sectional area of the cylinder (54),
wherein a maximum passage cross-section is between 10% and 15% of the internal cross-sectional area of the cylinder (54),
wherein the tension spring (101) has a tension force at a maximum effective length that is between twice and three times the tension force at a minimum effective length, and
wherein the tension force of the tension spring (101) is between 1.5 times and 3.5 times a sum of a static frictional force of the sliding door leaf (12) and a resistance of the cylinder-piston unit (51) with the maximum passage cross-section when the tension spring (101) is extended by a quarter of an effective stroke of the tension spring (101) beyond the minimum effective length.
