Damper assembly including valve connectors having one-way valves
A damper assembly includes an outer tube and an inner tube disposed in the outer tube defining a reserve chamber. The inner tube defines an inner volume. A piston is slidably disposed in the inner tube and divides the inner volume into a rebound working chamber and a compression working chamber. A rebound valve is fluidly connected to the rebound working chamber and the reserve chamber, and a compression valve is fluidly connected to the reserve chamber and the compression working chamber. A rebound valve connector fluidly connects the rebound valve and the rebound working chamber and a compression valve connector fluidly connects the compression valve and the compression working chamber. The rebound valve connector includes a one-way valve from the reserve chamber to the rebound working chamber and the compression valve connector includes a one-way valve from the reserve chamber to the compression working chamber.
