Abstract

A metal tube or conduit e.g. a vehicle oil sump pick up tube and filter housing is made by pressing two sheet metal blanks (6,7) to produce in at least one of them an elongate relieved portion (8), crimping the aligned edge portions (15,16) together such that the relieved portion defines a wall of the tubular item. The blank edge portions are then joined by brazing.

Description

2361443 METAL TUBULAR ITEM This invention relates to metal tubes and
conduits and components comprising such tubes and conduits especially, but not exclusively, for use in vehicle engines.
A vehicle engine may comprise an oil sump attached below the engine cylinder block and inside the sump an oil pick-up tube with a filter housing at one end, the housing having a mouth near the bottom surface of the sump so that the mouth does not become starved of oil when the vehicle turns a comer. The other end of the tube leads up to a port in the cylinder block, this port leading to the oil distribution system of the engine. The filter housing may be made from two or more sheet metal blanks which are pressed and crimped together while the tube is formed by bending to shape a length of solid drawn tubing. One end of the tube is secured, e.g. by a spot weld, to a union formed as part of the filter housing and a solid machined fixing flange for connection to the cylinder block port is positioned at the other end of the tube. The crimped blanks of the filter housing, with the filter gauze mounted therein, and the connections between the tube, filter housing and flange are brazed.
An object of the invention is to provide an improved component intended to reduce the cost of manufacture.
According to the invention there is provided a metal tubular item made by forming two sheet metal blanks, pressing or otherwise forming at least one of said blanks to form an elongate relieved portion therein, fixing the two blanks together by crimping aligned 2 edge portions of the two blanks, and further connecting the two together by fusing metal applied to said edge portions, said relieved portion defining a wall portion of the tubular items.
The item may comprise a component, for example a vehicle engine oil sump inlet, including a hollow metal housing communicating with a metal tubular item, the component being made by forming two sheet metal blanks each comprising portions for forming said tubular item and said housing and crimping and brazing the blanks together.
For a better understanding of the invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which:
Figure I is a front view of a sump oil pick up tube; Figure 2 is an exploded view of the Figure I tube; and Figure 3 is a section on the line 33 of Figure 1.
The sump oil pick up tube I illustrated is intended to be installed in a vehicle engine (not shown) and forms part of the engine lubrication system. The upper end of the tube comprises a flange 2 by which the tube is connected to the engine cylinder block (not shown). The tube is coupled to an oilway leading to the engine oil filter (not shown). The other end of the tube is coupled to a filter housing 3 including a mouth 4. The housing 3 contains a cup-shaped gauze filter element 5.
3 The tube I and housing 3 are made from two sheet metal blanks 6 and 7 which are press-formed so that each has an elongate relieved portion 8 for forming the walls of the tube I and respective portions 9 and 10 for forming the filter housing 3. The pressforming also produces the bend 12 in the tube 1 and respective inter-engaging portions 13 and 14 for forming the flange 2.
The peripheries of the formed blanks have lands 15 and 16, the land 16 of the lower blank being wider than the land 15.
With the gauze filter element 5 in place, the two blanks can be placed together and, in a further forming operation, the land 16 is turned up and over the land 15 and crimped tightly down onto the land 15.
To complete fabrication of the item, a flange stiffener piece 17 is engaged within the flange portion 13 of blank 6 and a cover member 18 is engaged with the housing part 10 to provide an angled mouth of the housing 3. The parts of the assembly are then fixed securely together and sealed by oven brazing.
The function of the angled mouth of the housing 3 is to ensure that the mouth of the housing is as close as possible to the floor of the engine sump (not shown) to avoid air being drawn into the lubrication system.
The particular shape of the oil pipe may of course be adapted to the requirement of the engine concerned. For example, it may be provided with a bracket for fixing to the 4 cylinder block and giving extra support to the tube. The bend(s) in the tube, the length of the straight section, and the angle of the mouth may be changed as appropriate.
It will be noticed that the bore size of the tube I can be varied, i.e. the tube can taper outwards from the filter end to the cylinder block end of the tube.

Claims (3)

1. A tubular metal item made by forming two sheet metal blanks, pressing or otherwise forming at least one of said blanks to form an elongate relieved portion therein, fixing the two blanks together by crimping aligned edge portions of the two blanks, and further connecting the two together by fusing metal applied to said edge portions, said relieved portion defining a wall portion of the tubular items.
2. An item, for example a vehicle engine oil sump inlet, including a hollow metal housing communicating with a metal tubular item, the component being made by forming two sheet metal blanks each comprising portions for forming said tubular item and said housing and crimping and brazing the blanks together.
3. An item substantially as hereinbefore described with reference to the accompanying drawings.
