Abstract
A simplified but highly efficient fluid-amplified liquid spring shock absorber is provided by incorporating a plurality of DeLaval nozzles in the piston head or dashpot head of a shock absorber.
Claims6
A shock absorber comprising:
- a housing means charged with a compressible fluid;
- sweeping means slidably disposed within said housing for traversing said housing means, said sweeping means separating said housing means into at least two chambers;
- and
- at least one DeLaval nozzle-shaped fluid passage disposed in said sweeping means and providing the exclusive means for the flow of fluid between said separated chambers formed in said housing means, said passage being configured to accommodate the flow of said compressible fluid at velocities approaching Mach 0.6 and greater and to produce a relatively constant resistance force with increasing fluid velocity therethrough, whereby the flow of said fluid through said passage at said velocities provides fluid amplification upon movement of said sweeping means.
