Description

[Detailed description of the invention] This invention relates to a resin container, and its purpose is to adjust the mounting position and direction of the connection pipe of the connecting hose connected to the inlet and outlet of the container, respectively. It is possible to freely set it in the required direction in response to changes.

Another object of the present invention is to improve the shape of the hollow container to increase the connection strength of the connecting pipe to the hollow container.

In order to reduce the weight of the oil container used in the pump for the power steering system of an automobile, a separate resin container is installed in the engine room and connected to the discharge port of the power steering system pump. The pump has an inlet connected to the suction port of the pump, and an outlet connected to the suction port of the pump.

Conventionally, connection pipes have been provided at the inlet and outlet of a container in order to connect a connection hose or the like to the inlet and outlet, but the connection pipe is molded integrally with the container.

This container is not always installed at a fixed position in the engine room, and the mounting position and direction of the container may change depending on the vehicle type and other conditions.

Therefore, in cases where the connecting pipe is molded integrally with the container as described above, it is necessary to prepare a mold for molding the container having the connecting pipe in a direction that matches the mounting position and direction of the container. However, depending on the orientation of the connecting pipe, it may be difficult to design and manufacture the mold.

If the connecting pipe is forcibly connected even though the direction of the connecting pipe does not correspond to the connecting direction, the connecting hose will bend at the connecting part and the fluid will not flow smoothly. cause problems.

This problem can be solved by using a molded hose bent at a predetermined curvature, but this has the drawback that the hose is a special product and the cost is high.

This invention solves the above problems, and the first problem is
The special feature of this is that the connecting pipe is molded separately from the container, is bent at the required angle, and the connecting pipe can be welded or oriented to the container in an appropriate direction depending on the mounting position and direction of the container. The second feature is that a thick wall portion is formed in the hollow container to increase the connection strength of the connecting pipe.

Embodiments of the present invention will be described below with reference to the drawings.

In Fig. 1, 1 indicates a hollow container made of resin, and 2
It is constructed by combining a divided upper half 2 and lower half 3.

A replenishment port 4 for replenishing fluid is opened at the upper end of the upper half body 2, and a cap 5 is detachably secured to the replenishment port 4.

The lower half-vacation 3 includes an upper cavity 3a and an upper cavity 3a.
A lower cavity 3b having a smaller diameter and eccentricity is formed, and a part of the inner circumferential wall of the lower half body 3 is made into a thick wall portion 3c, and an inflow port opening into the inner circumferential wall of the hollow container 1 is formed in the thick wall portion 3c. 6 is formed.

As is clear from FIG. 2, a crescent-shaped opening 7 is formed at the upper end of the inlet 6 and extends in the circumferential direction of the inner circumferential wall of the lower half 3.

Further, the lower half body 3 has an outlet 10 formed in its thick wall portion 3c and communicating with the bottom of the lower half body 3.

Furthermore, a filter mounting seat 15 is formed around the bottom of the lower half body 3 above the outlet 10, and a filter 8 made of wire mesh or the like is mounted on this.

This filter 8 is attached to an annular support frame 16 formed separately from the lower half body 3, and this support frame 16 is mounted and supported on the filter attachment seat 15.

As a means for fixing the support frame 16, a small hole 17 is opened at a suitable position in the support frame 16, and a protrusion 1 formed on the lower half body 3 is formed.
8 and fix the back of the head by heat caulking.

A rectifying plate 9 that covers the opening 7 above the inlet 6 and has a wall surface running parallel to the inner circumferential wall surface of the lower half body 3 is integrally formed on the support frame 16 .

Connecting pipes 11 and 12 formed separately from the lower half body 3 are attached to the inlet 6 and the outlet 10 by ultrasonic welding, friction welding, or adhesive bonding 13,14.

This connecting pipe 11.12 has a cylindrical insertion part 11a,
12a, and these insertion parts 11a, 12a are inserted into the cylindrical fitting holes 21, 22 of the hollow container 1, so that the centers of the connecting pipes 11, 12 are accurately aligned with respect to the inlet 6 and the outlet 10. matched.

Furthermore, the connecting pipe 11.12 has a welded flange portion 11b,
12b, and by welding or gluing these flange portions 11b and 12b in contact with the mounting surface of the hollow container 1, each connecting pipe 11, 12 is firmly fixed to the hollow container 1 at an arbitrary angular position. It is now possible to do so.

Note that the connecting pipes 11 and 12 are welded or bonded 13.
．． A large number of hoses having different bending angles θ1 and θ2 at the portion 14 are prepared, and one suitable for connecting the hose may be appropriately selected from among them.

Since the present invention has the above-mentioned structure, the hollow container 1 and the connecting pipes 11, 12 are formed separately, and the connecting pipes 11, 12 are connected in accordance with the mounting position and direction of the hollow container 1. It is welded or glued 13, 14 to the inlet 6 and outlet 10 in a direction suitable for connection with a hose or the like.

At this time, since the connecting pipes 11, 12 are bent, the direction can be freely set as required, and the connection can be made without bending the connecting hose.

In addition, in the hollow container 1, the fluid flowing in from the inlet 6 is prevented from blowing upward by the rectifying plate 9, preventing air from being mixed in, and the entire amount of fluid is rectified into a flow along the inner circumferential wall of the hollow container 1. , generate a vortex in the hollow container 1,
This vortex effectively separates air bubbles mixed into the fluid.

As described above, the present invention molds a connecting pipe for connecting a connecting hose, etc. to the inlet and outlet of a hollow container separately from the hollow container, and adjusts the connection pipe according to the mounting position and direction of the hollow container. The design of the hollow container can be changed even if the mounting position or direction of the hollow container is changed because the direction of the connecting hose is set in the direction that makes it easy to connect the connecting hose, etc., and welded or glued to the inlet and outlet respectively. There is an advantage that the connecting hose can be easily connected to the connecting pipe using a hollow container of the same shape, without the need to use a special molded hose.

Moreover, since the connecting pipe is bent, there is a degree of freedom when determining the direction in which it fits into the inlet and outlet.
It also has the advantage that the proper direction for connection with the connecting hose can be easily determined.

Further, the present invention forms an upper cavity and a lower cavity which is smaller in diameter and eccentric than the upper cavity in the resin hollow container, and makes a part of the inner circumferential wall of the hollow container a thick wall part. Since the thick wall part has an inlet opening to the inner circumferential wall of the hollow container and an outlet opening to the bottom of the hollow container, the insertion length of the connecting pipe can be increased, and this allows the connection As a result, even if bending force is applied to the connecting pipe and the hose inserted therein, the hollow container and the connecting pipe have the advantage of being prevented from being deformed or damaged.
