Description

[Detailed description of the invention] The present invention relates to a container made of resin, and its purpose is to prevent air from being mixed into the fluid flowing into the container from the inlet, and to prevent air from entering the fluid. The current plate can be easily installed in a predetermined position.

The oil container used in the power steering pump of an automobile is provided with an inlet connected to the discharge port of the power steering pump and an outlet connected to the suction port of the pump. In recent years, the development of a resin container separate from the pump has been progressing to reduce the weight of automobiles. However, since resin containers cannot have a resistance wall that can sufficiently withstand the inflow pressure at the upper end of the resin molded upstream inlet, the return oil that flows in from the inlet blows upward, stirring the oil in the container and releasing air. This was causing the pump for the power steering system to make abnormal noises.

The present invention provides a resin container that solves the above problems, and examples thereof will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a resin hollow container, which is constructed by combining an upper half 2 and a lower half 3, which are divided into upper and lower halves. The lower half body 3 is provided with a vertical inflow port 5 that is open in the vicinity of the inner circumferential wall 4 and in a tangential direction thereof. At the upper end of this inlet 5, a second
As shown in the drawings and FIG. 4, the upper wall 6 is molded with resin by forming a crescent-shaped opening 7. Further, an outlet 8 is provided at the bottom of the lower half body 3. Furthermore, a filter mounting seat 9 is formed around the bottom of the lower half body 3 above the outlet 8, and a filter 11 such as a wire mesh is mounted on this.

This filter 11 is attached to an annular support frame 12 formed separately from the lower half body 3, and this support frame 1
2 is mounted and supported on the filter mounting seat 9. As a means for fixing the support frame 12, the support frame 12
A protrusion 10 that fits into a small hole opened at a proper position is provided, and after the protrusion 10 is fitted into the support frame 12, the head part of the protrusion 10 is heat caulked as shown in FIG.
to become established.

Further, a rectifying plate 14 is integrally formed on the support frame 12 and has a wall surface that covers the upper opening of the inlet 5 and runs parallel to the inner circumferential wall 4 of the lower half body 3.

At the upper end of the upper half body 2 is a replenishment port 16 for replenishing fluid.
is opened, and a cap 15 is removably engaged with the supply port 16, and a level gauge 17 is integrally suspended from the cap 15.

Since the present invention has the structure as described above, in the case of a pump for a power steering device, the return oil from the discharge port is returned from the inlet 5 to the filter 11 in the hollow container 1, and the return oil is returned to the filter 11 in the hollow container 1. The filtered oil flows out from the outlet 8 to the suction port of the pump.

The return oil flowing in from the inflow port 5 is prevented from blowing upward by the rectifying plate 14 to prevent air from being mixed in, and the entire amount of the return oil is rectified into a flow along the inner circumferential wall 4 of the hollow container 1. A vortex is generated within the hollow container 1, and this vortex effectively separates air bubbles mixed into the return oil.

As described above, the present invention has the effect of preventing return oil from blowing up by the rectifying plate provided at the inlet, preventing air from entering by rectifying the flow along the inner peripheral wall of the hollow container, and separating air bubbles.
Since this rectifying plate is integrally molded with the support frame of the filter installed inside the hollow container, it has a separate structure from the hollow container body, making it easy to mold the hollow container body with resin, and making it easier to place the filter inside the container. By attaching it, there is an advantage that the current plate is installed at a predetermined position at the same time.
