Shock absorber electrical generator
First Claim
1. A shock absorber electrical generator, comprising:
- a substantially cylindrical, hollow shock absorber body having a first end, a second end longitudinally opposed from the first end, and a lower portion;
a hollow cap attached to the first end of the shock absorber body, the cap having a nitrogen fill valve adapted for introducing nitrogen gas into an interior portion of the shock absorber body, the cap sealing the nitrogen gas inside the shock absorber body;
a central tube internally disposed along a longitudinally central axis of the shock absorber body;
a piston assembly slidably disposed through the second end of the shock absorber body, the piston assembly including a central piston longitudinally sliding within the central tube and a larger, auxiliary piston longitudinally sliding within the lower portion of the shock absorber body;
power transfer tubes extending longitudinally alongside the central tube, the power transfer tubes forming power transfer chambers having inlets and outlets providing a circuit adapted for one-way flow of a working gas medium therethrough;
turbine fans disposed in the power transfer tubes, the turbine fans being adapted for rotary motion responsive to one-way flow of compressed working gas medium through the power transfer tubes;
electric generators housed in the shock absorber body, the generators being attached to the turbine fans, the turbine fans rotating to actuate the electric generators, thereby producing electrical energy from sliding displacement of the piston assembly within the shock absorber body; and
means for attaching the shock absorber body to a suspension and wheel assembly of a motor vehicle;
wherein a compression stroke of the piston assembly causes high pressure gas to flow unidirectionally through a first portion of the circuit, thereby causing rotation of a first portion of the turbine fans, and an expansion stroke of the piston assembly causes high pressure gas to flow unidirectionally through a second portion of the circuit, thereby causing rotation of a second portion of the turbine fans to produce electric current from motion of the piston assembly.

Abstract
The shock absorber electrical generator includes a piston adapted for reciprocating motion within a cylindrical piston chamber as a vehicle'"'"'s suspension system deflects. A working fluid is contained within the piston chamber. During the compression stroke of the piston, working fluid is forced through a circuit having at least one chamber in the cylinder opposite the piston. The working fluid communicates with at least one fan turbine motor disposed in the chamber, and with the piston chamber, which captures the working fluid on the return stroke. Upon compression of the piston, the working fluid passes through the fan turbine motor, thereby turning a shaft connected to a DC generator. The electric energy generated is routed to vehicle electrical components and/or charges the vehicle battery. Multi-generator systems, fan, and housing units are deployed in a plurality of shock absorber electrical generators that are attached to the vehicle'"'"'s wheel system.
