Abstract: A gas pressure spring is provided including an expanding wax as a compensating medium for reducing a temperature dependency of a spring force of the gas pressure spring in an operating temperature range of the gas pressure spring spanning a minimum temperature of −40° C. to +10° C. up to a maximum temperature of +40° C. to +100° C. The expanding wax includes at least one liquid phase and at least one solid phase in the entire operating temperature range, the expanding wax comprising a number of primary alcohols. Also provided is a drive system for a flap including a gas pressure spring for supporting the flap, and an electromechanical drive for driving the flap.

Abstract: Provided is a gas strut, including: an outer working space arranged radially to the stroke axis between the working cylinder and the equalizing cylinder, the outer working space being connected to the inner working space in a gas-conducting manner; an equalizing piston enclosing the working cylinder radially to the stroke axis, the equalizing piston) being mounted displaceably along the stroke axis, delimiting the outer working space on one side transversely to the stroke axis and being subjected to a pressure of the working medium and a pressure of the equalizing medium so as to increase the volume of the outer working space; and a restoring medium arranged in a restoring space radially to the stroke axis between the working cylinder and the equalizing cylinder, the equalizing piston being subjected to a pressure of the restoring medium so as to decrease the volume of the outer working space.

Abstract: A gas pressure spring is provided including a pressure tube and a fluid with a fluid pressure enclosed by the pressure tube in a fluid-tight manner in an operating state of the gas pressure spring. A wall of the pressure tube has a local taper, the taper forming a predetermined breaking point of the wall adapted to open to release a portion of the fluid from the pressure tube in a controlled manner when the fluid pressure exceeds a limit pressure. A wall thickness of the wall has a line-shaped minimum within the taper, the wall thickness increasing monotonically from the minimum to an edge of the taper in all circumferential directions around a longitudinal axis of the pressure tube. Also provided is a method of manufacturing the gas pressure spring.
