An actuator for displacing a movable pin between two end positions, at least one of which two end positions is a stop, comprises an energy buffer, components mutually connecting the energy buffer and the movable pin, a mass capable of storing energy of the energy buffer as kinetic energy, wherein at the end of the displacement in at least one direction the kinetic energy of the mass is stored again in an energy buffer, locking means which block the actuator in at least one extreme position when the remaining kinetic energy has been wholly or almost wholly generated to the energy buffer, and means with which the lost energy can be supplied at the end of the movement cycle, and is characterized in that between energy buffer and movable pin are situated at least two rotating components, i.e., an actuating element which drives the movable pin between two end positions, whereof the distance between the end positions in relation to each other is not necessarily determined, and a mass which moves along partly parallel with the actuating element, wherein kinetic energy is stored in the mass at the beginning and over only a part of the movement, on the basis of which kinetic energy the movement of the rotating components can be completed without other energy sources having to be applied for this purpose and whereof at the end of the movement the mass can rotate further relative to the actuating element, wherein the remaining kinetic energy of the mass is relinquished to the energy buffer. |
