Abstract
Systems are provided for a piston cooling jet system for cooling a piston of a locomotive engine. In one example, a piston cooling jet system includes a feed body hydraulically coupled to an oil reservoir and a pair of piston cooling tubes extending radially outwards, in opposite directions, from the feed body. The tubes may have showerhead outlet features at one end for uniformly spraying oil onto inlets of a piston oil gallery housed in the piston.
Claims19
A piston cooling system for a locomotive engine, comprising:
- a feed body hydraulically configured to be coupled to an oil reservoir, the feed body having a central axis;
- a first piston cooling tube extending laterally to protrude radially out from one side of the feed body relative to the central axis, the first tube having a first showerhead outlet element;
- and
- a second piston cooling tube extending laterally to protrude radially out from another side of the feed body relative to the central axis, the second tube having a second showerhead outlet element,
- wherein the first piston cooling tube comprises a first section and a second section, the first section protruding laterally outwards from one side of the feed body along a first longitudinal axis, and the second section extending from the first section along a second longitudinal axis, the first longitudinal axis at a first angle relative to the central axis, the second axis at a second angle relative to the central axis, the first showerhead outlet element extending upwards from the second section, and
- wherein the second piston cooling tube comprises a third section and a fourth section, the third section protruding laterally outwards from the other side of the feed body along a third longitudinal axis, and the fourth section extending from the third section along a fourth longitudinal axis, the third longitudinal axis at a third angle relative to the central axis, the fourth axis at a fourth angle relative to the central axis, the second showerhead outlet element extending upwards from the fourth section.

A cooling system in a locomotive engine, comprising:
- a feed body for receiving oil from an oil sump and dispensing oil to a cylinder piston, the feed body having a central cylindrical region with a central axis, a tapered upper end and a tapered bottom end;
- a first cooling tube having a first section extending upwards and protruding laterally outwards from one side of the central cylindrical region of the feed body along a first longitudinal axis, and a second section extending from the first section along a second longitudinal axis, the second axis at a first angle relative to the first axis, the first axis at a second angle relative to the central axis;
- and
- a second cooling tube having a first section extending upwards and protruding laterally outwards from another side of the central cylindrical region of the feed body along a third longitudinal axis, and a second section extending from the first section of the second cooling tube along a fourth longitudinal axis, the fourth axis at the first angle relative to the third axis, the third axis at the second angle relative to the central axis, wherein a respective outlet of the second section of each of the first and second cooling tubes has a large aperture surrounded circumferentially by a plurality of smaller apertures.

A locomotive engine system, comprising:
- a plate having a central aperture, a first support arm extending upwards from a first corner of the plate and a second support arm extending upwards from a second, diagonally opposite corner of the plate, each of the first and second support arms having a respective notch at an outer edge;
- a cylindrical oil feed body coupled in the central aperture such that a first portion of the feed body lies above a plane of the plate, and a second, remaining portion of the feed body lies below the plane of the plate;
- a first segmented tube protruding laterally from a first side of the first portion of the feed body, the first segmented tube including a first segment extending into and beyond the notch of the first support arm, and a second segment extending radially away from the notch of the first support arm, an outlet of the first support arm having a showerhead structure;
- and
- a second segmented tube protruding laterally from a second side, opposite the first side, of the first portion of the feed body, the second segmented tube having a third segment extending into and beyond the notch of the second support arm, and a forth segment extending radially away from the notch of the second support arm.
