Compression cut-off valve for a hydraulic damper |
摘要 |
A twin-tube hydraulic damper includes a fluid-filled cylinder tube closed at its lower end by a cylinder end. A piston is slidably mounted in the cylinder tube and divides an interior volume of the cylinder tube into upper and lower chambers. A plurality of intake slots permit fluid to flow from a reservoir to the lower chamber. A plurality of exit flow openings permit fluid to flow from the lower chamber to the reservoir. A cut-off cap is slidably mounted on the cylinder end and sprung away from the cylinder end by a reaction spring. An annular wall formed on the cylinder end receives the cap as the piston engages an activation spring near the travel limit of a compression stroke. Reduced fluid flow through the exit flow openings increases the damping force to reduce harsh impacts.
