ABSTRACT:
An apparatus for cushioning a body of a dump vehicle when the body is lowered, including structure defining a fluid passageway between first and second end portions of the structure. The structure is adapted to be disposed in a fluid pressure operated actuator used to raise and lower a body of a dump vehicle. When the structure is disposed in such actuator the passageway extends in a longitudinal direction of such actuator and the second end portion communicates with an interior of such actuator. A cushioning spool is adapted to be connected to such actuator for moving in the longitudinal direction into the passageway. A poppet includes an orifice that receives the spool for enabling the poppet to be slidably movable on the spool in the longitudinal direction.
