Abstract
A recoil damper (10) for a reciprocating member (12) mounted in a housing (24) includes a annular ring (38,138) mounted adjacent a shoulder (28) formed on the reciprocation member, the annular ring (38,138) mounted in a viscous fluid interior of the housing. The annular ring (38,138) cooperates with the shoulder (28) of the reciprocating member (12) to allow a relatively free flow of the viscous fluid around the shoulder (28) upon motion of the reciprocating member (12) in one direction and to restrict flow of the viscous fluid around the shoulder (28) upon motion of the reciprocating member (12) in the other opposite direction.
