The invention relates to a lay bar of a warp knitting machine which has at least a guide bar device arranged on a driving element. The driving element and a driving mechanism as well as at least a counter force element (5) are arranged in connection, wherein the counter force element (5) has a piston-cylinder-device. For the piston-cylinder-device, a piston connected to the driving element through a piston rod (6) can move in a cylinder (9) with a certain cylinder cross section in a stroke length (H) region and can be loaded through a pressure medium. People intend to keep the stress change in the driving element little. Therefore the cylinder (9) is arranged in a cavity (10) of a vessel (11) filled by the pressure medium. The cavity (10) has the capacity larger than the external capacity of the cylinder (9) and is in connection with an internal space of the cylinder (9) on a side surface of the piston (12) provided with a piston rod (6). The cylinder (9) is connected to the vessel (11) at at least two positions in a direction parallel to the stroke length (H). The two positions have an interval. |
