Abstract
The invention discloses a novel compression damping control valve, which comprises a valve body, a compression valve seat and a valve element, wherein the valve element is arranged on the compression valve seat and is provided with at least one valve element throttle hole; the lower end face of the valve element is in pressed joint with the valve body; and the valve body is supported by and connected with a compression spring. The control valve of the invention has the advantages that: oil passes through the valve element throttle hole to undergo primary throttling and pressure reducing first and then continues to flow, and the valve body opens gradually after counteracting the force applied by the compression spring; because a limiting piece is configured in design, the valve body is limited when moving to a place where the valve body contacts the limiting piece and the novel compression damping control valve avoids generating plastic deformation under a limit throttling strength; and thus, under the condition of bearing a heavier compression hydraulic load, the resistance of the compression valve to deformation caused by accidental impact is ensured, and the service life and safety factor of the product are improved.
