摘要

A power cylinder (100) is provided that includes a body (102) having a bore (106) therein, a piston rod (104) longitudinally reciprocable within the bore, and extending axially from the body. The power cylinder further comprises a groove (126) defined by the piston rod, wherein the groove is situated proximate a distal end of the piston rod, and wherein the groove circumscribes the piston rod. The power cylinder also comprises a bumper (122) having a size and dimension to engage the groove, wherein the bumper engages the groove, and wherein a face (136) of the bumper engages the body when the piston rod is in a substantially retracted position.
