A delivery system having a telescoping spring is used to drive a plunger. The telescoping spring includes a nested inner spring that uses the unused volume on the inside of an outer spring. The telescoping spring has a staged release of each spring. The inner spring is connected to a non-anchored end of the outer spring, and rides within a container located within an inner dimension of the outer spring. The spring constant K of each spring can be the same or different. The delivery system can be fully mechanical or implemented as a smart delivery system under electronic control.

A furniture drive for retracting a movably supported furniture part into a closed position relative to a furniture carcass includes a housing, an entrainment member which can be releasably coupled to the movable furniture part, a spring device for applying a force to the entrainment member, and a guide path arranged or formed on the housing. The entrainment member is displaceably arranged along the guide path, and the guide path includes a first bend for releasably locking the entrainment member. The guide path includes at least one second bend for releasably locking the entrainment member, and at least one movably-supported switch element with a first and with a second switching position is provided. The switch element, in the first switching position, blocks the first bend so that the entrainment member can move into the second bend and the switch element, in the second switching position, unblocks the first bend so that the entrainment member can move into the first bend.

The invention relates to a spring unit, a spring accumulator, and an actuator. The spring unit comprises at least one spring element, which has a part that can be deflected against a spring force, and a compensation device, which is designed to counteract the spring force more strongly in the case of a more greatly deflected part than in the case of a less greatly deflected part. The spring accumulator comprises such a spring unit. The actuator comprises such a spring unit and/or such a spring accumulator.
