Abstract
A valve, particularly a pressure relief valve for the lubricating oil filter of an internal combustion engine, which includes a valve plate 11, a valve body 10 cooperating with the valve plate, a valve spring 14 and a valve hood 15, the valve spring 14 being supported on the valve hood 15 and exerting a force on the valve plate to seal the opening between the valve plate and the valve body. A cylindrical guide 24 is provided at the upper end of the valve hood, and the valve plate 11 contains a blind bore 25 which receives the cylindrical guide in order to guide the valve plate.
Claims8
A valve comprising a valve body having a valve opening therethrough and a valve plate having a valve seat thereon which cooperates with said valve body to close said valve opening, a valve hood secured to said valve body enclosing said valve plate, and a valve spring supported against said valve hood for urging said valve plate toward said valve body to seal said valve opening;
- wherein said valve body is a cylindrical body having at one end facing said valve seat a bead margin under which said valve hood is crimped to secure said valve hood to said valve body;
- wherein said valve hood has a circumferential flange which is crimped under said valve body bead margin to secure said valve hood to said valve body, a plurality of openings above said flange distributed around the circumference of said valve hood through which a fluid flowing through said valve can pass, and a cylindrical valve plate guide at the upper end of said hood;
- and wherein said valve plate is formed with a blind guide bore at one end facing said cylindrical valve plate guide for receiving said cylindrical guide in order to guide said valve plate.
