<P>PROBLEM TO BE SOLVED: To provide an improved cover assembly such as a valve cover assembly, which has improved fastening performance and closing performance, and reduces fluid leakage such as oil leakage. <P>SOLUTION: A flanged cover assembly includes a cover having a wall portion, a lateral flange surrounding the wall portion extending outwardly therefrom and a plurality of spaced flange bores extending through the flange from an upper surface to a lower surface. The bores are adapted to receive a plurality of corresponding fasteners which are adapted to be inserted through the bores and secure the cover to a base. The cover assembly also includes a spring retainer which is adapted to extend along at least a portion of the outer surface of the lateral attachment flange. The spring retainer has a plurality of spaced retainer bores corresponding to at least two of the spaced flange bores and at least one shaped spring portion that is adapted to contact the upper surface of the lateral attachment flange between the spaced flange bores. <P>COPYRIGHT: (C)2012,JPO&INPIT |
