Abstract:
A cooling water delivery tube assembly for use in an internal combustion engine of a locomotive to provide water between an inlet aperture of a power pack and an outlet aperture of a manifold, the inlet aperture and outlet apertures longitudinally offset from each other and disposed in misaligned planes, the assembly comprising:a corrugated metal pipe having inlet and outlet ends; a metal braid surrounding the pipe; inlet and outlet housings operatively coupled to the inlet and outlet ends of the pipe, respectively; mounting flanges integrally formed with each housing, respectively, the flanges having a mounting face; the inlet and outlet housings defining an internal fluid flow path in fluid communication with the pipe; the inlet and outlet housings having compound angles defining the fluid flow path such that when the inlet housing is secured to the power pack and the outlet housing is secured to the manifold, the corrugated metal pipe is maintained in a substantially linear configuration between the housings; the inlet housing including first, second, and third integrally formed sections defining the internal fluid flow path, the first section integrally formed with the flange, the third section operatively coupled to the inlet end of the pipe, and the second section formed between the first and third sections, wherein the first section is axially aligned with the face of the flange, the second section is disposed at about a ninety-nine degree angle relative to the first section, the third section is disposed at about ninety-nine degree angle relative to the second section, and the third section being rotated at about a thirty-one degree angle away from the plane of the flange face; and the outlet housing including a curved section having first end and second straight ends defining the internal fluid flow path, the first section integrally formed with the flange and the second end operatively coupled to the outlet end of the pipe, wherein the radius of curvature of the curved section extends through an angle of about eight-six degrees such that the second straight end is disposed at about a four degree angle relative to a plane of the flange, and the curved section being rotated at about a thirty-one degree angle about an axis normal to the plane of the flange face.
