Abstract
A snubber with an integral test structure which permits the snubber to be tested for drag, lockup and full load pressure characteristics without disconnecting it from between two external members between which it is mounted including a cylinder with opposite end walls, a piston mounted on a piston rod extending through the end walls and dividing the space between the end walls into first and second chambers which are filled with hydraulic fluid, a first clevis connecting one end of the piston rod to a first external member, a housing mounted for sliding movement on the cylinder and including a second clevis connecting it to a second external member, a plurality of selectively removable pins for fixedly attaching the housing to the cylinder or permitting it, when removed, to slide relative thereto, and ports in communication with the two chambers for conducting hydraulic liquid thereto or exhausting hydraulic liquid therefrom.
