ABSTRACT:
A hydro-mechanical compression and rebound stop 22 for a suspension strut 10 in which a tubular sleeve 30 is coaxially mounted about a piston rod 18 and is positioned by a coil spring 26 which has its other end seated against a fixed annular seat 24. An abutment ring 50 engages the bottom end of the sleeve 30 to force the sleeve through the annular seat 24 against the bias of the spring and to cause a hydraulic restricted hydraulic flow therethrough. Upon rebound, the abutment ring 50 compresses an elastomeric sleeve 48 against a rod guide 43 at the top end of the working cylinder 12.
