Abstract:
A universal joint assembly has a housing and a universal joint in a chamber within the housing. A diaphragm seal in the housing forms a wall of the chamber. The chamber is substantially sealed to exclude entry of foreign elements. The diaphragm seal is flexible to allow for expansion and contraction of the chamber due to changes in temperature to prevent any substantial increase or decrease in the pressure within the chamber.
