Abstract
A fluid pump includes a plastomer spring. The spring includes a first end portion and a second end portion and a plurality of rhombus shaped spring sections, joined together in series at adjacent corners and aligned with each other in an axial direction to connect the first end portion to the second end portion. The spring sections can be compressed in the axial direction from an initial condition to a compressed condition and can subsequently expand to their initial condition.
