Abstract: A valve adapted for use with an internal combustion engine comprising a body having a passage therethrough and a valve element including a valve head and a valve stem. The valve element is mounted for movement on the body so that the valve head can open and close the passage. The valve stem projects through a bore in the body and has an insurance member mounted thereon which is engageable with an abutment to limit the maximum amount of opening of the valve. A peripheral wall substantially circumscribes the insurance member when the latter engages the abutment to prevent removal of the insurance member. The valve is biased toward a closed position by a spring which extends between the body and a valve spring retainer. The valve spring retainer is mounted on the valve stem by a split ring which is received in a counterbore in the valve spring retainer.

Abstract: A method for manufacturing a metallic component including the steps of providing a capsule, which defines at least a portion of the shape of the metallic component, arranging metallic material in the capsule, sealing the capsule, subjecting the capsule to Hot Isostatic Pressing for a predetermined time, at a predetermined pressure and at a predetermined temperature, and optionally, removing the capsule. The metallic material is at least one pre-manufactured coherent body, which pre-manufactured coherent body being made of metallic powder, wherein at least a portion of the metallic powder is consolidated such that the metallic powder is held together into a pre-manufactured coherent body. At least one portion of the pre-manufactured coherent body is manufactured by Additive Manufacturing by subsequently arranging superimposed layers of metallic powder.
