Description

[Detailed Description of the Invention] The present invention relates to a large-capacity overflow device using a plurality of small overflow elements, which is mass-produced for use in automobile engines and the like.

By the way, in relatively large internal combustion engines,
As a supercharger used in a fuel system, etc., it is common practice to use a device in which multiple small, mass-produced superelements used in automobile engines etc. are installed in parallel. When installing elements, it is necessary to provide a passage inside the mounting base, which is usually made of casting, to connect the entrances and exits of each element in parallel.
Casting is extremely troublesome, resulting in high manufacturing costs, and when the passages are formed by piping, problems arise such as the oversize vessel becoming larger.

The present invention was developed in view of the above circumstances, and is an overheating device that uses a plurality of mass-produced small-sized elements to achieve the required capacity. A passage connecting the entrances and exits of each element in parallel is formed by a partition plate interposed between the above-mentioned two cases and a connecting pipe with one end fixed to the partition plate, thereby forming a passage by casting inside the mounting base. This avoids the trouble and reduces the manufacturing cost, and also makes the entire device more compact.

This will be explained below using an example shown in the figure.
In Figure 1, 1 indicates upper case 2 and lower case 3.
The lower case 3 and the partition plate 4 form an inlet port 6 for fuel, etc., and the partition plate 4 interposed between the two cases is integrated with a plurality of bolts 5. Further, an outlet port 7 is formed by the upper case 2 and the partition plate 4, and an inlet pipe 8 and a delivery pipe 9 for fuel, etc. are connected to both ports, respectively. 10 is a plurality of openings formed on the bottom surface of the lower case 3; 11 is a partition plate 4;
Each element 12 closes the opening 10 with its main body upper end surface 13a, and each element 12 closes the opening 10 with its main body upper end surface 13a. It is screwed onto the protrusion of the connecting pipe. Here, the element 12 has a structure in which a cylindrical member 14 is housed inside a main body 13, and an inlet 12a formed on the upper end surface 13a of the main body communicates with the opening 10 of the lower case when the element 12 is screwed onto the communication pipe 11. , and the outlet 12b of the element that has passed through the material is connected to the communication pipe, and the inlet 12a and the opening 10
The periphery of the communication portion is sealed with an O-ring 15.

According to the above configuration, fuel and the like introduced into the inlet port 6 by the inlet pipe 8 are caused to flow into the plurality of elements 12 from each opening 10 in the lower case 3 via the inlet 12a of the main body 13, and are also allowed to flow into each element. Contaminants are removed by passing through the material 14 inside the material, and then the material is allowed to flow from the space inside the material through the outlet 12b and the communication pipe 11 into the outlet port 7 of the mounting base 1, and is merged at the port. After that, it is sent out through the delivery pipe 9. The same holds true when three or more elements are attached, and an overcontainer having a desired capacity can be obtained using the standardized small-sized elements.

Next, the embodiment shown in FIG. 2 will be explained.
21 is an element mounting base, 22 and 23 are an upper case and a lower case that constitute the mounting base, 24 is a partition plate interposed between both cases, and 31 is fixed to the partition plate at one end and is provided in the lower case. A plurality of communication tubes 32 are made to protrude to the outside through an opening 30, and a plurality of elements 32 are screwed onto the protrusions, which are similar to the embodiment shown in FIG. However, in this embodiment, the inlet port 26 formed by the lower case 23 and the partition plate 24 is opened below the mounting base 21 through a through hole 23a provided in the lower case 23, and
The through holes 24a and 22a provided in the partition plate 24 and the upper case 22 are also opened above the mounting base, and the outlet port 27 formed by the partition plate 24 and the upper case 22 is also opened through the through holes 22.
b, 23b, and 24b open above and below the mounting base, and a through hole 23a that opens below.
An introduction pipe 28 and a delivery pipe 29 are respectively connected to 23b, and a through hole 22 that opens upward
a, 22b are closed by blind lids 36, 36, which allow the passage from the inlet pipe 28 to the inlet port 26, each element 32, and the connecting pipe 31 as in the embodiment of FIG.
A passageway leading to the delivery pipe 29 via the exit port 27 is formed, and if this is used as one set and another set is prepared, it will open above the mounting base 21 by removing the blind cover 36. Through hole 22
The inlet pipe 28' and the delivery pipe 29' of another set can be attached to a and 22b, which makes it possible to arrange a large number of elements in two or three or more stages, resulting in an even larger capacity superconductor. is obtained.

As described above, the present invention has an element mounting base composed of an upper case and a lower case, and a partition plate interposed between the two cases, a connecting pipe with one end fixed to the partition plate, etc., which allows multiple elements to be mounted. Since the structure forms a passage connecting the inlets and outlets in parallel, a large capacity overload container using multiple small mass-produced elements can be realized.
Since the mounting base of each element is divided into an upper case and a lower case as described above, a passage connecting each element is formed inside the conventional integrated mounting base, or each element is connected with piping. The manufacturing process has become much easier compared to the conventional case, and together with the use of mass-produced and inexpensive elements, this type of large-capacity overload device can now be provided at an extremely low price. Moreover, since a large number of elements can be arranged compactly, it is possible to achieve effects such as being significantly smaller than other overpass units having the same capacity.
