Rigid Locking In Compression, Relatively Rigid In Extension
The function is similar to that of a K type, but with the oil and gas chamber on the opposite side. This means that the spring is rigid up to the mechanical strength of the spring in the compression direction. In the extension direction, the locking is rigid until the force of the pressure on the floating piston is exceeded (locking force).
