  • Patent number: 9964171
    Abstract: A damper assembly (20) is disclosed, and it comprises: a first rube (22) defining an inner surface (24) extending along an axis (A) to define a fluid chamber (30) containing a damping fluid (32); a rod (34) extending axially in the first rube (22); a guide (40) annularly disposed about the rod (34) and engaging the first tube (22); a piston (42) and a retainer (46) which are attached to the rod (34) and are slidably disposed in the first tube (22); a first spring (50) engaging and extending axially away from the retainer (46); a valve body (52) which is disposed adjacent to the first spring (50) and has a periphery (54) spaced from the inner surface (24) of the first tube (22) to define an annular channel (60); a second spring (66) extending axially away from the valve body (52); a bumper (68) engaging the second spring (66). The valve body (52) moves into sealing engagement with the retainer (46) in response to the bumper (68) engaging the guide (40).
