The present disclosure relates to a mechanical energy storage for a fluid dispensing device (10), the mechanical energy storage comprising:a first drive spring (51) extending along a longitudinal direction (z),the drive spring (51) comprising a first longitudinal end (53) to engage with a housing (10) of the fluid dispensing device (1) and a second longitudinal end (54) opposite to the first longitudinal end (53) to engage with a driver (30) movable relative to the housing (10) along the longitudinal direction (z),wherein the mechanical energy storage (50) is reversibly transferable into a pre-loaded state by resiliently compressing the first drive spring (51) in the longitudinal direction (z) to thereby induce a resilient deformation of the first drive spring (51) in a first direction (y) transverse to the longitudinal direction (z), and-wherein the mechanical energy storage (50) is transferable from the pre-loaded state into an unloaded state by allowing the first drive spring (51) to relax into or towards an undeformed configuration with regard to the first direction (y) accompanied by a longitudinal expansion of the first drive spring (51).

A copper-coated steel wire includes a core wire made of a stainless steel, and a coating layer made of copper or a copper alloy and covering an outer peripheral surface of the core wire. In a cross section perpendicular to a longitudinal direction of the core wire, the outer peripheral surface of the core wire has a value of an arithmetic mean roughness Ra of not less than 25% and not more than 90% of a thickness of the coating layer.

A torsion spring may be formed as a bar spring or helical spring comprising a spring wire of fiber composite material. In some examples, the torsion spring comprises a number of layers of fiber reinforcement, which are impregnated with a matrix material. The layers may comprise tensile-loaded fibers and compression-loaded fibers. Groups of layers of the same loading direction may exist and, seen from an inside to an outside, the group stiffness of at least two groups may differ. Likewise, methods for making such torsion springs of fiber composite material are disclosed.

An energy absorbing cell has a first structural element, a second structural element disposed parallel to and spaced apart from a first structural element, a first intermediate member, and a second intermediate member. Each intermediate member is disposed at an angle between the structural elements. A first end and a second end of each intermediate member are respectively attached to the structural elements. The intermediate members are formed from an elastic material. The angles of the intermediate members are selected such that application of a compressive force to displace the structural elements toward one another triggers a snap-through instability in both intermediate members. The energy absorbing cell is used, singly or in combination with one or more other energy absorbing cells, to form energy absorbing structures, such as vehicle bumpers or highway barriers, adapted to control the deceleration of an object impacting the energy absorbing structure.

First to Nth plate-shaped members (N: an integer not less than 3) are arranged at multiple stages. The plate-shaped member for a kth number counted from the first plate-shaped member is defined as a kth plate-shaped member (k: integers from 2 to N1). The first plate-shaped member has a first wire support portion. The kth plate-shaped member has a kth through hole through which a (k1)th wire support portion of the (k1)th plate-shaped member penetrates. A (k1)th wire suspending the kth plate-shaped member is provided at an upper part of the (k1)th wire support portion penetrating through the kth through hole. A kth wire support portion is provided adjacently to the kth through hole in a predetermined rotational direction around a reference point on the kth plate-shaped member.
