An arrangement with or in the form of a gas spring, comprising a first and second gas chamber with one or more devices separating these, which devices are arranged to increase the volume of the first chamber and reduce the volume of the second chamber, or vice versa, when a difference in pressure arises in the chamber. The invention also relates to a method for determining the spring characteristics of a gas spring, with the spring characteristics being created only by a first device, by means of which the space in the gas cylinder is divided into a first gas chamber and a second gas chamber, or in combination with a second device which is arranged in an additional chamber, which is divided by the second device into a third chamber and a fourth chamber that are connected to the first chamber and the second chamber respectively. The first or second device is arranged as a separating device that brings about an increase in the volume of the first chamber or the third chamber and a reduction in the volume of the second chamber or the fourth chamber, or vice versa, in response to a pressure difference between the first chamber and the second chamber or the third chamber and the fourth chamber. By means of the invention, a gas spring is obtained that is compact and divides up movement, and that has advantageous spring characteristics and a large gas volume.
Gas spring intended for a vehicle and comprising a gas cylinder with a piston operating in the gas cylinder that divides the cylinder into two chambers by means of at least one divider arranged between the piston and the cylinder, wherein the divider functioning between the gas cylinder and the divider functioning between the gas cylinder and the piston is arranged to be able to be moved relative to the piston and/or the cylinder in a direction parallel to the direction of operation of the gas cylinder.
Arrangement with or in the form of a gas spring that comprises first and second gas chambers and one or more separating devices for separating the first and second gas chambers wherein the separating device(s) are arranged to increase the volume of the first chamber and to reduce the volume of the second chamber, or vice versa, when a difference in pressure arises in the chamber.
Method for determining the spring characteristics of a gas spring wherein the gas spring of comprises a gas cylinder, and wherein the damping characteristic or damping characteristics are created only by means of a first device including a first piston provided with a piston rod, by means of which piston the space in the gas cylinder is divided into first and second gas chambers, or in combination with a second device including a second piston or divider that is arranged in an additional chamber which is divided by the second device or the second piston or divider into a third chamber and fourth chamber that are connected to the first chamber and the second chamber respectively, wherein the first and second devices are arranged as separating devices that bring about an increase in the volume of the first chamber or the third chamber and a reduction in the volume of the second chamber or the fourth chamber, or vice versa, in response to a difference in pressure between the first chamber and the second chamber or the third chamber and the fourth chamber.
