Fluid damper for bodies that are movable relative to one another, comprising a piston that is movably guided in a cylinder

A fluid damper for bodies adjustable relative to one another having a piston (4) guided adjustably in a cylinder (1), wherein in the piston (4) and/or between the piston (4) and the cylinder (1) at least one through opening (4.2) for through-flowing fluid is embodied, having adjusting means for adjusting a limitation of at least the maximum possible through-flow cross section of the fluid at the at least one through opening (4.2) of the fluid damper ready for operation;

• said the piston (4) is connected to a piston rod (6) leading out of the cylinder (1);
• said adjusting means having a detent connection (2), which holds the piston (4) in a desired position in the cylinder (1);
• and said detent connection is mounted radially nonrotatably on the end of the piston rod, located in the cylinder;
• wherein the adjusting means include a notched disk (7), secured nonrotatably on the piston rod (6), by means of which adjusting means at least one notch (7.1) of the through-flow cross section of the fluid at the location of the at least one through opening (4.2) of the piston (4) and/or between the piston (4) and the cylinder (1) is pre-adjustable.

• and said detent connection is mounted radially nonrotatably on the end of the piston rod, located in the cylinder;
• wherein the closing element includes at least one wing (3.1) supported rotatably in the piston (4), which wing, upon motion of the piston (4) relative to the cylinder (1) in a first direction, as a function of the speed or pressure on the piston rod (6), progressively closes the through opening (4.2) in the piston (4) and/or between the piston (4) and the cylinder (1) counter to a spring loading, and upon motion of the piston (4) counter to the cylinder (1) in a second direction opposite the first direction the spring loading restores the wing (3.1) and opens the through opening (4.2).
