ABSTRACT:
A railcar cushioning device includes an elastomeric spring and a hydraulic shock absorber member. The fluid accumulator is located outside of and above the fluid chambers. The accumulator is in communication with the fluid chamber in a non-stroked position, causing entrapped air to be displaced by the fluid, into the accumulator. Free of air, the shock absorber immediately responds to impact forces. The elastomeric spring reduces peak impact forces and returns the piston of the shock absorber to its non-stroked position. The elastomeric spring also absorbs draft forces.
