Abstract
A monotube shock absorber assembly includes a housing (), a gas cup () slidably disposed in the interior () of the housing (), and a piston () slidably disposed in the interior () of the housing () to define an oil compression chamber () between the piston () and the gas cup (). A cushion () engages one of the piston () and the gas cup () and extends axially into the oil compression chamber () for intermittent contact with the other of the piston () and the gas cup (). The cushion () is a resilient material and deforms in response to the cushion () contacting the other of the piston () and the gas cup (). In a preferred embodiment, the cushion () defines a central opening () for decreasing the axial stiffness of the cushion () and engages the gas cup () for intermittent contact with the piston (). In a preferred embodiment the cushion () presents an anchor () for retaining the cushion () against the piston () for intermittent contact with the gas cup ().
