Shock absorbing arrangement for marine outboard drive |
摘要 |
A shock absorbing arrangement integrates in a compact manner into a fluid motor of a tilt cylinder, and consequently is particularly well suited for a small outboard drive that may only have a slimed tilt cylinder. The shock absorbing arrangement is provided in a piston for permitting flow from the first chamber to the second chamber upon the application of a predetermined force tending to cause the outboard drive to tilt-up. The shock-absorbing mechanism comprises a check valve assembly accommodated in a hollow space that is formed in the piston and is closed by a plug attached to the piston. A piston rod extends through the first chamber from the piston and is separately formed with the piston. The piston rod includes a passage that communicates with the hollow formed in the piston. A diameter of the passage provided in the piston rod is larger than the diameter of a valve seat for the check valve assembly in order to reduce fluid friction loss across the shock-absorbing valve assembly.
