Abstract

Abstract A reinforced stamped valve cover including an elongated housing having a trough-like configuration including an elongated base wall, a pair of spaced, elongated side walls attached to and extending from one side of the base wall, and a pair of spaced, relatively short end walls extending from the base wall and adjoining the end walls. The walls are stamped from a single sheet of metal and are provided with an outwardly directed ledge substantially surrounded by a peripheral flange. A pair of spaced, U-shaped strengthening members are disposed within the housing with each having a bight and a pair of legs extending therefrom. Each bight is configured to substantially conform to the base wall and is in substantial abutment therewith. Each leg abuts a corresponding one of the side walls along substantially the entire extension thereof from the base wall and past the ledge to define with the flange a gasket-receiving pocket. The legs are configured to conform to the corresponding side wall and the strengthening members are secured in spaced relation to the housing.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 198 words
A valve cover comprising: an elongated housing having a trough-like configuration including an elongated base wall, a pair of spaced, elongated side walls attached to and extending from one side of said base wall, and a pair of spaced, relatively short end walls extending from said base wall one side and joining said end walls, said walls being stamped from a single sheet of metal, with the ends of said side and end walls terminating in an outwardly directed ledge having a peripheral flange directed away from said base wall and substantially surrounding said ledge, said flange being generally parallel to said side and end walls; a pair of spaced, U-shaped strengthening members disposed within said housing, each having a bight and a pair of legs extending therefrom, each said bight being configured to substantially conform to said base wall one side and being in abutment therewith, each said leg abutting a corresponding one of said walls along substantially the entire extension thereof from said base wall and past said ledge to define, with said flange, a gasket receiving pocket opening away from said base wall; and means securing said strengthening members, in spaced relation, to said housing.
Claim 2
Dependent Claim 198 words
A valve cover comprising: an elongated housing having a trough-like configuration including an elongated base wall, a pair of spaced, elongated side walls attached to and extending from one side of said base wall, and a pair of spaced, relatively short end walls extending from said base wall one side and joining said end walls, said walls being stamped from a single sheet of metal, with the ends of said side and end walls terminating in an outwardly directed ledge having a peripheral flange directed away from said base wall and substantially surrounding said ledge, said flange being generally parallel to said side and end walls; a pair of spaced, U-shaped strengthening members disposed within said housing, each having a bight and a pair of legs extending therefrom, each said bight being configured to substantially conform to said base wall one side and being in abutment therewith, each said leg abutting a corresponding one of said walls along substantially the entire extension thereof from said base wall and past said ledge to define, with said flange, a gasket receiving pocket opening away from said base wall; and means securing said strengthening members, in spaced relation, to said housing.
