The invention refers to a spring arrangement for a revolving device in a housing, e.g. a gas throttle in an internal combustion engine. The spring arrangement is comprised of two, around a bearing axel parallel to the working pull-back springs, which at their respective one end are set up in order to affect the device and in their respective other ends are designed to fit up against a fixed turning holding-up tool. In known execution methods for parallel operating pull-back springs a spring is used on each side of the throttle. This involves troublesome and costly mounting and additionally such arrangements often demand too much space. In the above named invention, the downsides are eliminated and the invention is characterized by the spring arrangement being made of a spring packet (7) comprised of an outer spring (9) which is mainly concentrically designed with an inner spring (8), the outer spring (9) and the inner spring (8) are connected to each other in their respective axial ends by two end plates (10, 11) that are shaped in order to interfere in the turn of winding of the springs (8, 9). The springs are concentrically arranged around the storage axle (4) and through this they obtain a compact construction which does not require greater space than if only a spring was used.<IMAGE> |
