Patents by Inventor Eric Prinster

Eric Prinster has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Combined Air Spring and Damper
    Publication number: 20240060544
    Abstract: A suspension system includes a first compression chamber and a second compression chamber with a damping chamber therebetween. The compression chambers may be independently filled with a compressible fluid, and the relative pressures may govern the rebound rate of the suspension. Seals that minimize friction, an adjustment system, and a stop are also included to enhance rider joy.

  • Shock absorber incorporating a floating piston
    Patent number: 11376913
    Abstract: A shock absorber includes a first end and a second end that reciprocate relative to one another. The shock absorber includes a gas spring chamber, a damping chamber, and a floating piston. The first side of the floating piston is in fluid communication with the gas spring chamber. The second side of the floating piston is in fluid communication with the damping chamber. The gas in the gas spring chamber applies pressure against the floating piston, which applies pressure to the substantially incompressible fluid in the damping chamber. This pressure transfer may be adequate to minimize or prevent cavitation.

  • Shock absorber gas spring seal
    Patent number: 9731574
    Abstract: A shock absorber includes a first portion and a second portion that reciprocate relative to one another. The shock absorber includes a gas spring chamber defined between an interior wall and a plunger. A seal including a lip portion minimizes gas pressure loss and friction between the two portions.
