Abstract
A damper assembly includes a housing. A method of forming a damper assembly includes extruding the housing formed of aluminum. The housing defines a first chamber and a first passage spaced from each other, with a first inlet fluidly connecting the first chamber and the first passage. A piston is disposed in the first chamber and is movable in a first direction and a second direction opposite the first direction. A first restrictor valve is disposed in the first passage. The first restrictor valve is configured to restrict a flow of liquid into the first passage from the first chamber and the first inlet as the piston moves in one of the first and second directions which causes the liquid in the first chamber to increase a pressure applied to a first side of the piston to dampen movement of the piston.
