Latest Patents
Hiroyuki Hayama's latest patents include a fluid pressure shock absorber and a damping force adjustable fluid pressure shock absorber. The first patent describes a fluid pressure shock absorber where the valve opening of the main valve is controlled by the inner pressure of a backpressure chamber. This design features a first piston and a second piston coupled to a piston rod, fitted in a cylinder, creating a piston chamber. The arrangement allows for stable damping force generation and enhances the durability of the main valves.
The second patent focuses on a damping force adjustable fluid pressure shock absorber. In this design, an intermediate chamber is formed between the first and second pistons, with check valves provided at each piston. The inner pressures of the backpressure chambers are adjusted by a damping force adjusting valve, allowing for controlled valve openings. This innovative approach prevents sudden changes in hydraulic fluid pressure, ensuring a stable damping force.
