Abstract
A snubbing arrangement functions to control the rate of deceleration of a piston and rod assembly within a fluid cylinder as the piston and rod assembly nears the bottom of the piston cavity. A flow blocking mechanism is attached to the piston and rod assembly and acts to block flow from the piston cavity through a first head end port. A pressure differential valve mechanism is disposed between a second head end port and the rod end port and operative to control the pressure in the head end cavity relative to the pressure in the rod end cavity.
