Abstract

The invention relates to a spring unit including mechanical spring means (1) having a spring direction and being located between a first spring support (2) and a second spring support (3), which first (2) and second (3) spring supports are movable in relation to each other in the spring direction. The spring unit further comprising a first actuation member (4) facing the rear side (22) of the first spring support (2) and a second actuation member (5) facing the rear side (32) of the second spring support (3), which first (4) and second (5) actuating members are movable relative to each other and relative to the first (2) and second (3) spring supports in the spring direction.According to the invention, the first actuation member (4) is arranged to be able to apply a pushing force to the first spring support (2) and includes first pulling means (6) arranged to be able to apply a pulling force to the second spring support (3), and the second actuation member (5) is correspondingly arranged. Thereby a relative movement of the first (4) and second (5) actuation members towards each other as well as a relative movement of the first (4) and second (5) actuation members away from each other result in compression of the spring means (1).
