    摘要： Provided is a valve stem seal which exhibits superior workability of mounting of a reinforcing ring to a valve stem guide and which enables the reinforcing ring to be fixed to the valve stem guide in a stable manner. A reinforcing ring is mounted to a valve stem guide by fitting a cylindrical portion to the valve stem guide from a side opposite to an inward flange portion. The cylindrical portion is provided with a slit extending linearly in a circumferential direction and a locking protrusion that is provided on a side opposite to the inward flange portion with respect to the slit and that is to be locked by a locking recess formed in the valve stem guide. The locking protrusion is constituted by a curved portion that is gradually recessed radially inward from the side opposite to the inward flange portion with respect to the slit to a position that reaches the slit.

    摘要： A method of manufacturing an annular component is provided. The method comprises the steps of providing an annular shell (90) to form the outer wall of the component and a plurality of flat annular rings wherein a radially inner edge of each ring is shaped to correspond to a cross-section of the shell at a different position along its length. The method comprises attaching each ring to the ring(s) adjacent to it at a plurality of circumferentially spaced discrete positions. The method comprises deforming each flat annular ring into a corrugated three-dimensional shape, wherein the corrugations extend out of the flat plane and comprise radially defined peaks and troughs. The method comprises locating the shell (90) within the plurality of attached, deformed annular rings (91-95). The method comprises attaching the plurality of attached, deformed annular rings (91-95) to the shell (90) to form the component, so that the plurality of attached, deformed annular rings (91-95) provide structural reinforcement to the shell (91-95).

    摘要： The present invention provides a method of producing a fuel distribution pipe 10 to be attached to a cylinder head. The method includes providing a forged bar made of metal, forming a main bore 14 in the forged bar so as to extend along an axial direction of the forged bar, forming an injector bore 25 having an injector opening in the forged bar, forming a bolt through hole 22 having a bolt opening in the forged bar, obtaining a base pipe having the main bore 14, the injector bore 25, and the bolt through hole 22 from the forged bar, and bending the base pipe such that the injector opening of the injector bore 25 and the bolt opening of the bolt through hole 22 are provided along a line parallel to the axis of the main bore. The injector bore 25 directly communicates with the main bore 14 and the bolt through hole 22 does not communicates with the main bore 14.
