Temperature-driven valve assembly

A gas pressure spring comprising two separated chambers for accommodating a fluid, wherein the chambers are connected to each other through a valve assembly, the valve assembly comprising:

• a) a channel portion for the fluid-conducting connection of the two chambers for accommodating the fluid having a through opening for the fluid;
• b) at least one switching element having an opening configuration in an opening temperature range and a closing configuration in a closing temperature range;
• b1) wherein the at least one switching element is, at least in sections, movable relative to the channel portion along an axis of movement in a temperature-driven manner;
• b2) wherein an opening normal of the through opening is oriented towards the switching element, and
• b3) wherein the channel portion circumferentially enclosed by a channel wall around the axis of movement;
• and
• c) at least one sealing means circumferentially extending around the channel wall;
• c1) wherein the at least one sealing means, in a mounting position, abuts on at least one sealing surface of the channel wall, a surface normal of the sealing surface being oriented towards the at least one switching element;
• c2) wherein the at least one sealing means, in the mounting position, cooperates, in a sealing manner, with the at least one sealing surface and the at least one switching element (8) in the closing configuration and closes the through opening;
• and
• c3) wherein the at least one sealing means, in the mounting position, is spaced apart from the at least one switching element in the opening configuration along the axis of movement so that a primary fluid path connects the two chambers through the through opening and between the at least one switching element and the at least one sealing means in a fluid-conducting manner,
• d) at least one recess in the channel wall,
• d1) wherein a projection of the at least one recess along the axis of movement is, enclosed by a projection of the at least one sealing surface along the axis of movement, and
• d2) wherein, in an operating position of the sealing means in which the at least one sealing means is spaced apart from the at least one sealing surface along the axis of movement, a secondary fluid path connects the two chambers to each other in a fluid-conducting manner through the at least one recess.
