Abstract
A shock absorber includes a housing and an end wall slidably disposed within the housing. The end wall and the housing cooperate to define at least a portion of a cavity within the housing. The cavity is filled with a fluid, and a piston is slidably disposed within the cavity. Movement of the piston within the cavity compresses the fluid to provide a spring force. The shock absorber further includes a compensator coupled to the end wall. The compensator positions the end wall within the housing to change a volume of the cavity in response to a change in a temperature of a first element of the compensator.
Claims19
A shock absorber, comprising:
- a housing;
- an end wall slidably disposed within the housing, the end wall and the housing cooperating to define at least a portion of a cavity within the housing;
- a fluid disposed within the cavity;
- a piston slidably disposed within the cavity, movement of the piston within the cavity compressing the fluid to provide a spring force;
- and
- a compensator coupled to the end wall, the compensator comprising:
- a first element coupled to the housing and having a first coefficient of thermal expansion;
- and
- a second element coupled to the first element and to the end wall, the second element having a second coefficient of thermal expansion different than the first coefficient of thermal expansion,
- wherein the compensator positions the end wall within the housing to change a volume of the cavity in response to a change in a temperature of the first element.
A shock absorber, comprising:
- an outer housing portion comprising an end wall;
- an inner housing portion at least partially disposed within and slidingly engaging the outer housing portion;
- a piston slidably disposed within the outer housing portion, wherein the outer housing portion, the inner housing portion, and the piston cooperate to define at least a portion of a cavity;
- and
- a compensator selectively positioning the piston relative to the outer housing portion, wherein the compensator moves the piston relative to the outer housing portion to change a volume of the cavity in response to a change in a temperature of the compensator.
