Gas spring system having at least one gas spring

A gas spring system having at least one gas spring with a cylinder closed at a first end, a piston arrangement displaceably arranged in the cylinder, which arrangement divides the cylinder into a first working chamber near the first end and a second working chamber remote from the first end, and a piston rod arranged on one side of the piston arrangement, which rod projects through the second working chamber and is led out of the cylinder concentrically to the longitudinal axis (L) of the cylinder at a second end opposite the first end, sealed by a seal and a piston rod guide, wherein the cylinder has at least one overflow channel connectable to the working chambers for the automatic push-out movement of the gas spring wherein at least one retaining region of the cylinder which interrupts the overflow channel is provided for limiting the stroke of the piston arrangement in which the automatic push-out movement is blocked, wherein the piston arrangement is designed as a piston packet that is closed depending on direction, wherein the piston packet is designed in a springless manner and has an annular sealing element which is provided for sealing between the retaining region of the cylinder and the piston arrangement during a push-out movement of the gas spring wherein the piston packet has a further annular sealing element, which is provided for static sealing between piston arrangement and piston rod, and wherein the sealing element is arranged and displaceable in a radially outer annular space of the piston packet such that the sealing element can be pressed against the cylinder with a first pressing force during a push-out movement of the gas spring, and can be pressed against the cylinder with a second, lower pressing force during a push-in movement of the gas spring, wherein the piston packet has a piston and a stop disk and the piston, with a projection extending in the axial direction relative to the longitudinal axis (L), rests against the stop disk in such a manner as to form the radially outer annular space.
