Abstract
A shock absorber has a pressure tube, a piston slidably disposed in the pressure tube and a piston rod attached to the piston and extending out of the pressure tube. The end of the piston rod extending out of the pressure tube defines a contoured surface which can be engaged to prohibit rotation of the piston rod. In one embodiment the contoured surface is defined by an inner surface of a bore. In another embodiment, the contoured surface is defined by an exterior surface of an extension to the piston rod.
Claims18
A strut assembly comprising:
- a telescoping device having a telescoping rod;
- a first seat mounted to said telescoping device;
- a second seat mounted to said telescoping device;
- a spring mounted between said first seat and said second seat;
- wherein
- an end of said telescoping rod defines a contoured surface such that engagement of said contoured surface with a stationary device prohibits rotation of said telescoping rod.
