Abstract: The invention relates to a piston-cylinder unit (100) comprising a cylinder (110) filled with a fluid (150), a piston (120) slidably guided in the cylinder (110), a piston rod (130) attached to the piston (120), a seal (140), and a lubricant in contact with the seal (140) and with the cylinder (110), the piston (120) and/or the piston rod (130). The lubricant is a polyalphaolefin oil or a polyalkylene glycol oil. The seal (140) is made of chlorine-free acrylonitrile butadiene rubber. The invention also relates to a method for producing the piston-cylinder unit (100).

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.
