Base Valve With Open Bleed Tuning Capabilities

A shock absorber for a vehicle including a pressure tube, a reserve tube, a piston assembly, and a base valve assembly. The base valve assembly has a valve body including a rebound flow passage, a first circumferential land surrounding the rebound flow passage, a second circumferential land surrounding a bleed flow passage, and a third circumferential land surrounding a compression flow passage. The base valve assembly may further include a rebound valve assembly, a bleed valve assembly, and a compression valve assembly. The rebound valve assembly may be selectively driven into engagement with the first circumferential land, the bleed valve assembly includes a first portion that may be selectively driven into engagement with the second circumferential land and a second portion spaced apart from the valve body, and the compression valve assembly may be selectively driven into engagement with the third circumferential land.
