防ぐものもある。(Prior Art) A valve having a coil spring is used as a relief valve of a conventional oil filter. In such a valve, a valve body and a coil spring are housed in a valve case that has an inlet and an outlet, the valve body is placed on one end of the coil spring, and the other end is placed around the outlet and the valve body is placed around the outlet. is pressed against the inlet. Therefore, when the differential pressure of the fluid between the outlet and the inlet becomes large, the coil spring is compressed and the wires come into close contact with each other, blocking the flow path. As a countermeasure to this problem, as disclosed in Utility Model Application No. 55-20735, a valve body holder with a passage is provided between the valve body and the coil spring, so that even if the coil is in close contact with the valve body, the valve body holder will not disturb the coil spring. There is an example in which a fluid flow path is ensured. Furthermore, as disclosed in Japanese Utility Model Application No. 58-195161, a cylindrical stopper with a slit that serves as a fluid flow path is disposed inside the coil, and the stopper supports the valve body to limit its movement. There are also some that prevent the coils from sticking together.

算が複雑となる。(Problems to be solved by the invention) In the conventional type as described above, the valve body holder and stopper must be placed inside the valve chamber, so when assembling the valve, there is a risk of forgetting to assemble these parts or misaligning the assembly position. In such cases, there is a concern that the operation may be inaccurate and the intended function may not be achieved. This type of valve must satisfy desired conditions in terms of pressure, flow rate, pressure loss within the valve, etc. when fully opened. However, if there is a valve body holder or stopper as in the conventional model, the influence of these components on the above specifications must be considered comprehensively, making the design calculations to achieve the desired function complicated. Become.

機能を備えさせることが容易かつ確実となる。(Function) Due to the fixed piece attached to the coil spring, even if the valve body receives fluid pressure and the coil spring is compressed, the lines to which the fixed piece is attached will come into close contact with each other and block the fluid flow path. There isn't. Also, since multiple valves are installed, the spacing can be maintained evenly and no uneven load is applied to the valve body. Also, since the valve body holder and stopper are eliminated, there is no need to forget to install them when assembling the valve, and the specifications for when the valve is fully open can be determined using only the coil spring, making it easy to equip the valve with the desired function. And it becomes certain.

A valve 1 includes a spherical valve body 5 and a coil spring 6 that presses the valve body 5 toward the inlet 3 in a valve case 2 having a fluid inlet 3 and an outlet 4. Three fixing pieces 9 are attached to the coil spring 6 between adjacent coil wires 7 and 8. The fixed piece 9 is a thin metal rod, and both ends are wound around the coil wires 7 and 8.
A fixed portion 9a is formed. A straight portion 9b is formed between the fixed portions 9a at both ends, and its length is equal to the distance between the wires 7 and 8 when the coil spring 6 is under no load. The shape of the fixed part 9a is bifurcated with the line 7,
8 may also be used.

It may be attached to a coil with two or more turns. This valve is, for example, a bracket 2 to which an oil filter 20 is attached as a relief valve 10, as shown in FIG.
It is incorporated into the bypass passage 22 of No. 1.
