ザーバへのエアの混入を防止することである。[Detailed description of the invention] This invention relates to a resin reservoir, and its purpose is to provide a rectifying plate at the upper opening of the inlet to rectify the flow of return oil and to direct air to the reservoir. The purpose is to prevent contamination.

原因となる。 In general, the reservoir of the power steering system pump has:
There is an inlet connected to the exhaust port of the power steering device and an outlet connected to the pump suction port, but in recent years, in order to reduce the weight of automobiles, a resin reservoir separate from the pump has been installed. Development is underway. However, since a resin reservoir cannot have a sufficient wall at the upper end of the resin-molded upstream inlet, the return oil flowing in from the inlet blows upward, agitating the oil in the reservoir and mixing in air, which causes power steering. This may cause abnormal noise in the equipment pump.
本考案は上述した問題点に鑑みてなされたもの

的に垂下されている。 The present invention has been devised in view of the above-mentioned problems, and embodiments thereof will be described below with reference to the drawings. 1 and 2, numeral 10 indicates a resin hollow container constituting a reservoir, and this hollow container 1
0 is formed by combining an upper half body 11 and a lower half body 12 which are divided into upper and lower halves. The lower half 12 has a vertical inlet 14 that is adjacent to the inner circumferential wall 13 and opens in a tangential direction thereof, and a vertical inlet 14 that is opened along the inner circumferential wall 13 in correspondence with the tangential opening of the inlet 14. A protruding guide plate 15 and a radial outlet 16 opened at the bottom of the lower half 12 are integrally formed. A filter mounting seat 17 is formed inside the lower half body 12, and a disc-shaped filter 18 is inserted into the mounting seat 17 before the upper half body 11 and the lower half body 12 are joined together. Upper chamber 1 with inlet 14 opened by this filter 18
2a and a lower chamber 12b having an open outlet 16 are separated from each other, and return oil flowing in through the inlet 14 passes through a filter 18 and then flows out through the outlet 16. A replenishment port 19 for fluid replenishment is opened at the upper end of the upper half body 11, and a lid member 20 that closes the replenishment port 19 is removably locked to the upper half body 11, and a level gauge is attached to the lid member 20. 21 are integrally suspended.

る。 The upper wall 23 of the inlet 14 cannot be formed over the entire circular cross section of the inlet 14 when resin molding the lower half body 12, and has a substantially crescent shape as shown in FIGS. 2 and 3. The opening 24 is opened upward. Therefore, if the hollow container 10 molded from resin is used as it is, a portion of the return oil that has flowed in from the inlet 14 will flow into the upper opening 2.
4 and stirs the oil contained in the reservoir to mix air therein, and at the same time, the generation of vortices due to the formation of the guide plate 15 is made insufficient.

流されるようになる。 To this end, the present invention includes a vertical piece 25 joined to the side wall of the guide plate 15 and a horizontal piece 26 whose one end overlaps the upper wall 23 of the inlet 14, as shown in FIGS. 4 and 5. A rectifying plate 27 made of a spring steel material or the like having an L-shaped cross section is provided, and this rectifying plate 2
A slit 28 formed at the bent portion of the vertical piece 25 and the horizontal piece 26 is locked to the upper wall 23, and one end 25a of the vertical piece 25 is bent and engaged with the guide plate 15 to be attached to the lower half body 12. It is designed to be retained. Such a rectifier plate 27
This compensates for the shortage of the upper wall 23 of the inlet 14 and covers the upper opening 24, preventing the return oil that has flowed in from the inlet 14 from blowing upward, and the entire amount of return oil is distributed between the rectifying plate 27 and the guide. Guided by the plate 15, the flow is rectified along the inner circumferential wall 13.

に行い得るようになる。 Therefore, according to the present invention, the provision of the rectifier plate 27 prevents the return oil that has flowed in from the inlet 14 from blowing upward, thereby preventing air from being mixed in. Since the entire amount of return oil flows along the inner circumferential wall 13 and creates a vortex, the vortex can effectively separate air bubbles mixed into the return oil.

アの混入を防止できる効果が奏せられる。 As described above, the present invention has a configuration in which the reservoir is made of resin and the defect in the formation of the resin-molded upstream inlet opening is compensated for by the addition of a rectifying plate. This can be easily achieved, and since the return oil can be prevented from blowing upward from the inlet opening and the return oil can be rectified into a flow along the inner circumferential wall, the effect of preventing air from entering can be achieved.
