ABSTRACT:
A vortex flow shock absorber includes a piston having a vortex chamber therein. The piston communicates with one fluid chamber defined in a absorber cylinder via a vortex chamber and with the other fluid chamber separated from the former by the piston via a flow restricting opening. One-way valve is provided in a piston rod which defines a fluid passage permitting one way flow of the fluid from the vortex chamber to one of the fluid chamber. The one-way valve is responsive to an excessive fluid pressure in the vortex chamber to relieve the fluid pressure exceeding a predetermined value. The piston and piston rod are attached together with pressure welding. This simplifies the assembling operation of the piston onto the piston rod.
