Compressing valve system for damper of trailer

The present invention relates to a damper, a valve system particularly for use on one kind of the damper. The present invention provides An enclosing the outer tubing between the tubing and the end cap with the right port of the catching groove, for compressing the damper valve train trailer, which includes, in order from left to right structure, including nested tubing the right port, by the inner cover bottom groove fixation buckle tubing valve, compensator spring, a compression valve element, compensation sheet, compression of the valve sleeve, the valve sleeve in turn the compression sleeve and the small end of a small spring valve spring seat sleeve compression valve seat on the bottom of the small spring. The compression valving member compensation function will move the other side of the compression member function, so that the valve system has sufficient stiffness and sealing properties, sufficient to ensure the establishment of a compression damping force, effective solution to the air Cheng problem.
