US 2026/0201936 A1 · RESERVOIR SHOCK ABSORBER

Abstract

A piston valve assembly for a reservoir shock absorber, the piston valve assembly includes a piston. The piston includes a first side and a second side, wherein the second side is opposite the first side. The piston also includes one or more compression ports and one or more rebound ports, each passing from the first side to the second side. The piston valve assembly also includes a first washer on the first side, wherein the first washer covers all the one or more rebound ports on the first side and a first parabolic disk, the first parabolic disk in partial contact with the first washer. The piston valve assembly further includes a second washer on the second side, wherein the second washer covers all the one or more compression ports on the second side and a second parabolic disk, the second parabolic disk in partial contact with the second washer.
