Abstract:
An elastomer damper for receiving a piston sliding in a cylinder of an actuator cylinder at the stroke end thereof comprising:a base portion fixed to an end cap to be attached to an end of the cylinder, the base portion being disposed in the cylinder and having an outer end attached to the end cap and an inner end facing the piston in the cylinder and extending from the outer end;at least one protruding portion projecting from the base portion beyond the inner end in the direction toward the piston in the cylinder;wherein the protruding portion has a tapered shape such that a cross sectional area perpendicular to the longitudinal axis thereof gradually decreases in the direction toward the piston from a portion where it merges with the outer end of the base portion and wherein the protruding portion is disposed in the cylinder in such a manner that a clearance is provided around and between the periphery of the protruding portion and the inner end of the base portion in order to allow the protruding portion to expand in the direction perpendicular to the longitudinal axis thereof when the piston abuts the protruding portion at the stroke end.
