A dispensing pump includes a spring assembly and a locking arrangement to prevent the dispensing head from being deployed and/or actuated during shipment, stocking and pre-purchase handling. The dispensing pump includes a pump base, and a dispensing head having a piston stem. The spring assembly includes a slotted tubular spring element and first and second loading cones received at opposing ends of the slotted tubular spring element. Various locking arrangements may include interacting rotatable lugs provided between the dispensing head and the pump base, snap beads to retain the piston and dispensing head in a secured shipping position, and recyclable locking rings disposed between the dispensing head and pump base which prevent an active dispensing head from being actuated.

Suspension system of a vehicle and a shock absorber assembly of the suspension system, the shock absorber assembly includes a top mount and a jounce bumper. The jounce bumper includes a main body made of an elastic material, such as a foam elastomer or rubber and a fixing element made of a second harder material. The fixing element has a wall portion that extends around the outermost upper part of the main body and at least one elastic retaining area cooperating with a respective protuberance arranged in the top mount to fix the jounce bumper to the top mount. Between the outermost upper part of the main body and the fixing element there is a gap that enables the main body to expand radially also in the area covered by the wall portion of the fixing element when the main body is compressed during use.

A damping stopper is interposed between two members axially displaced relative to each other and is provided with an elastic body which, when the interval between the two members decreases, is axially compressed by the two members and expands radially outward. In the elastic body, a second member suppressing the expansion is located in one axial region and attached to the outer periphery. When axially compressed by the two members, the elastic body expands while receiving resistance by the second member. The expanding elastic body contacts the side wall of one of the two members.

Embodiments described herein relate generally to apparatus with ribbed structures or geometries for stiffness and damping control, and methods of producing the same. In some embodiments, an apparatus includes a ribbed structure having a set of ribs, configured to deform elastically under shock. In some embodiments, the set of ribs can have a sinusoidal wave shape. In some embodiments, the set of ribs can have a heterogeneous wave shape. In some embodiments, the set of ribs can have material properties that change along the length of the ribbed structure, such as wavelength, amplitude, wave shape, and material thickness.

Various embodiments of the present technology may provide methods and apparatus for a 3D-printed spring. The 3D-printed spring may be formed from a plurality of toroidal elements spaced apart from each other and connected with a plurality of connectors. Each connector connects one toroidal element to a directly adjacent toroidal element.
