Gas pressure spring comprising an expanding wax, drive system comprising the gas pressure spring

A gas pressure spring comprising 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 +50° C. to +100° C.,

• a. wherein the expanding wax comprises at least one liquid phase and at least one solid phase in the entire operating temperature range;
• b. wherein the expanding wax is composed of a number of alkanes and a number of primary alcohols having chain lengths which differ from each other;
• c. wherein the primary alcohols constitute a percentage of the substance amount of 10% to 30% of the expanding wax;
• and
• d. wherein the primary alcohols contained in the expanding wax
• i. comprise a number of primary alcohols having a lower melting temperature than all alkanes contained in the expanding wax, and/or
• ii. comprise a number of primary alcohols having a higher melting temperature than all alkanes contained in the expanding wax.
