Claim Text:
1. A mechanical dampener comprising: a) a housing defining a hermetic chamber having an axis; b) first and second counter-acting members spaced apart along the axis and displaceable along the axis for receiving external compressive loads compressing the first and second counter-acting members towards one another; c) a working liquid contained within the chamber; d) a set of plates received in the chamber between the first and second counter-acting members and movable towards one another substantially along the axis under compression of the first and second counter-acting members, the set of plates having a resilient geometry forming a spring providing a resistance by an inherent spring force against compression of the first and second counter-acting members in the axial direction by separating the plates axially by at least one inter-plate gap to allow ingress of the working liquid, such that in response to a compressive load applied on the first and second counter-acting members that exhibits an input force exceeding the inherent spring force, the plates are movable towards one another to squeeze out at least a portion of the working liquid in the at least one inter-plate gap.
