Cushion stop for hydraulic cylinder

A cushioning device in a hydraulic cylinder comprising, a hydraulic cylinder including a sleeve, a cap removably fastened on the end of said sleeve, a piston reciprocally mounted in said sleeve defining an expansible chamber with said cap, means defining a port in said cap, a check valve in said cap connected between said port and said expansible chamber providing inward flow from said port to said expansible chamber, means defining a plunger chamber connected between said port and said expansible chamber, a plunger received in an opening in said cap and extending into said plunger chamber axially aligned with the reciprocal movement of said piston, resilient means biasing said plunger toward said piston, means defining a central opening in said plunger forming an orifice on an inner end of said plunger communicating with said expansible chamber, radial openings axially spaced along said plunger connected to said central opening selectively closing and restricting fluid flow through said radial openings and limiting flow from said expansible chamber to said port as said plunger is pressed toward said cap as said piston reaches the end of the stroke to thereby provide a cushioning of said piston at the end of its stroke.
