Description
k 1 2219049 DISTRIBUTOR The present invention relates to a
lubricatingfluid distributor, for example for distributing lubricating fluid from a pump to a plurality of parts to be lubricated. It also relates to a method of manufacturing a distributor.
A lubricating-fluid distributor of the kind 10. referred to above comprises a body which is formed with a main flow passage and a plurality of branch flow passages. The main flow passage is connected to a main pipe which, in turn, may be connected to a discharge port of a pump. The branch' flow passages branch off 15. the main flow passage, and may communicate respectively with a plurality of discharge ports. Air-vent valves and a closure plug may be mounted to the body.
Conventionally, it is usual that the distributor 20. body is made of zinc alloy by means of die casting. Zinc alloy is low in corrosion resistance. In particular, zinc alloy tends to be corroded by material having a high or low pH, such as water-soluble cutting fluid or the like. In the worst case, an operational 25. malfunction of the distributor may occur.
Further, if many ports are required for the distributor, a mould must be used which. has correspondingly many ports or, alternatively, a 30. plurality of distributors must be used which are connected to each other. In the former case, the mould is large and expensive and difficulties may also be encountered in the moulding operation. In the 1 i- 2 latter case, defects tend to occur in connecting components and portions, allowing lubricating f luid to leak.
5.
It is an object of the invention at least to the above problems.
It is another object of the invention to provide a method of manufacturing a lubricating-fluid distributor 10. in an easy and simple manner.
In order to achieve the first-mentioned object, there is provided a lubricating-fluid distributor comprising a main pipe arranged to be connected to a is. discharge port of a pump of a lubricating system, and a body having a main flow passage communicating with the main pipe and a plurality of discharge ports communicating with the main flow passage, the body being made of a corrosion-resistant material.
20.
30.
In order to achieve the second object, there is provided a method of mdnufacturing a lubricating- fluid distributor which comprises a main pipe arranged to be connected to a discharge port of a pump of a lubricating system, and a body having a main flow passage communicating with the main pipe and a plurality of discharge ports communicating with the main flow passage, the method including the step of extruding the body from a corrosion-resistant material.
The corrosion-resistant material may comprise aluminium alloy, nickel alloy, stainless alloy, plastics material and so on.
n i 3 -il Fig. 1 is a partially broken-away, side elevational view of a lubricating- fluid distributor according to an embodiment of the invention; and 5.
Fig. 2 is partially cross-sectional view of the lubricating-fluid distributor illustrated in Fig. 1. _ _Referring to Figs. 1 and 2, there is shown a 10. lubricating- fluid distributor 10 having a main body 2. The body 2 is formed with a main flow passage 3, a plurality of branch flow passages 3A branching off the main flow passage 3, and a plurality (for example three) discharge ports 5,6 and 7 connected to the 15. respective branch flow passage 3A. The main f low passage 3 has one end which communicates with a main pipe 1 which, in turn, is connected to a pump P through a line Ll. The main pipe 1 is mounted to the distributor body 2 by a nipple 8. The other end of the 20. main flow passage 3 is closed by a blind screw 4. The body 2 is provided, in position, with air-vent valves-9 and 12 which are threadedly engaged with respective threaded bores formed in the distributor body 2. The air-vent valves 9 and 12 are sealed by seal rings 13 25. and 14, respectively.
A plurality of such distributors 10, 10A and 10B are connected to the pump P through lines L1, L2 and L3, respectively.
30.
The body 2 of the lubricating-fluid distributor 10 is moulded by extrusion of a corrosion-resistant material. An extrusion mould used for the extrusion 4 moulding is employed in such a manner that the material is extruded perpendicularly to the plane of Fig. 2 so as to have the cross-sectional shape illustrated in Fig. 2. Alternatively, the direction of extrusion may 5. lie in the plane of f igure 2. The extruded elongate article is cut into a length corresponding to a required number of distributing ports, so that there is provided a distributor body having the requisite number of ports. The air-vent valves and the blind screws are 10._ then mounted to the distributor body. Thus, the lubricating-fluid distributor is completed.
The above-described corrosion resistant material may be any material which has a strong resistance to 15. the lubricating fluid. It is preferable, however, that the corrosion resistant material is an aluminium alloy, nickel alloy, stainless alloy, plastics material or the like.
20. Th e main f low passage 3 may be extruded by means of a mould integrally with the body 2, and simultaneously with the same.
With the embodiment described above, it is 25. possible to mass-produce, at low cost, lubricatingfluid distributors which have a high corrosion resistance against the action of lubricating fluid.
