[Industrial applications]

 The present invention relates to a radiator injector used for injecting a coolant (coolant) into a radiator.

[0002]

[Prior art]

 In order to inject the coolant in the coolant replacement work, the coolant contained in a container such as a rectangular parallelepiped can was directly injected from the filler port of the radiator. Tongue-like injection pieces are attached to one corner of the upper surface of containers such as cans to guide the coolant to be poured out.

However, in this method, since the diameter of the filler port is small, no matter how the tip of the injection piece is made thin, it is necessary to carry out the operation while holding the can. Also, due to the blowback of air from inside the radiator due to coolant injection, the coolant often scatters and pollutes the engine room, body, etc., and must be cleaned after the injection work is completed. In addition, it is troublesome and time-consuming and troublesome because the above-mentioned filling work must be carried out with the cans held.

[0004]

[Problems to be solved by the device]

 Then, this invention makes it a subject to make it possible to inject automatically by just attaching directly to a filler port.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. (First Embodiment) FIG. 1 is a front view showing a state in which a coolant injector 1 is attached to a filler port 3 of a radiator 2. As shown in this figure, the coolant injector 1 is a coolant injector. It is composed of a tank 4 to be stored and a fitting cap 5 fixed to the lower end of the tank 4.

The tank 4 is made of a transparent or milky white translucent synthetic resin whose inside can be visually recognized. The capacity thereof corresponds to the amount of coolant injected into the radiator 2, for example, 1 liter, and accommodates a predetermined amount of coolant.

As shown in FIG. 2, a lid body 7 that can be peeled off with a thin portion 6 interposed is integrally formed on the upper end formed in a cylindrical shape. If this lid 7 is removed, it becomes an injection port 8 for filling the coolant and venting air. Alternatively, the entire lid 7 may not be peeled off and a part of the lid 7 may be left without being thinned so that the lid 7 to be peeled off can be held. Reference numeral 9 in the figure denotes a knob for peeling off the lid body 7.

Further, the tank 4 has a cylindrical spout 10 formed in the lower portion, and a collar 11 is integrally formed on the outer peripheral surface of the spout 10. The collar 11 is provided for stabilizing the posture of the tank 4 by contacting the lower surface with the upper surface of the mating cap 5 when the above-mentioned mating cap 5 is fixed. It may be appropriately set according to the upper surface of the fitting cap 5 and the size of the tank 4.

As shown in FIG. 3, the above-mentioned fitting cap 5 is composed of a lower member 12 and an upper member 13 which rotate relative to each other in the horizontal direction. The material is preferably rubber or soft synthetic resin, and when connected, it is formed into a tapered cone shape as shown in FIG.

The lower member 12 is formed so that it can be attached to various filler ports 3 having different diameters (see phantom lines in FIG. 4), and a generally semicircular outflow passage 14 is vertically formed inside. Is formed so as to penetrate through. Further, an annular connecting protrusion 15 is erected on the upper surface so that the upper member 13 and the upper member 13 can be rotated relative to each other. The connecting projection 15 has a thicker upper end in order to prevent it from coming off easily.

The upper member 13 is formed with a fixing recess 16 having an appropriate depth on the upper surface so that the spout 10 at the lower end of the tank 4 can be fixed by pressure bonding or adhesion. In addition, a substantially semicircular outflow passage 17 is formed vertically below the fixing recess 10, and the connecting projection 15 is fitted to the lower member 12 at a position corresponding to the connecting projection 15. The corresponding annular connecting grooves 18 are formed.

The above-described outflow passage 17 and the outflow passage 14 of the lower member 12 can be made to flow out of the coolant by rotating the lower member 12 and the upper member 13 so as to overlap with each other, as shown in FIG. If they are staggered like this, the outflow becomes impossible. The flow rate can be adjusted by narrowing or widening the overlapping area. It should be noted that it is advisable to mark on the peripheral surfaces of the lower member 12 and the upper member 13 at least at positions where the outflow is impossible due to grooves, protrusions, colors or the like.

In order to inject the coolant into the radiator 2 with the coolant injector 1 thus configured, the lower member 12 of the fitting cap 5 is attached to the filler port 3 and then the lid formed on the upper end of the tank 4. The body 7 may be peeled off to open the inlet 8, and the fitting cap 5 may be twisted so that the coolant is poured out. Then, the coolant in the tank 4 is injected into the radiator 2 through the spout 10 and the outflow passages 14 and 17 of the fitting cap 5. If it is necessary to replenish the coolant, it may be done from the inlet at the upper end of the tank 4.

Therefore, since the fitting cap 5 fixed to the lower end of the tank 4 is directly attached to the filler port 3 and the required simple operation is performed, the injection can be automatically performed. Moreover, since the filler cap 3 is closed by the fitting cap 5, the coolant injected from the filler port 3 does not scatter around. Therefore, the work is simple, the time required for the injection work can be shortened, and other work can be performed during the injection.

Further, since the tank 4 is formed to be transparent or semi-transparent, it is possible to see the decrease amount of the coolant, the state of pouring out, the degree of air escape, etc. even from a distance, and adjust the pouring amount. To ensure proper injection of coolant.

Further, since the fitting cap 5 is configured to be compatible with any filler port 3, it is not necessary to change the fitting cap 5 according to the type of the filler port 3, and the work is easy. Further, since the fitting cap 5 has the function of a cock, the overall shape is compact and the number of parts can be reduced and the manufacturing cost can be reduced as compared with the case where a separate cock is provided. In addition, since it is only necessary to twist the fitting cap 5, proper coolant injection work is easier.

Furthermore, the work of opening the injection port 8 only needs to be stripped off, and the work is simple.

Further, since the collar 11 is formed at the spout 8, the load applied between the fitting cap 5 and the tank 4 can be supported, and the mounting state can be stabilized.

Other Embodiments For example, the tank 4 may be provided with a screw-type lid body 21 as shown in FIG. In this case, the coolant does not have to be stored in advance and can be repeatedly used as a device for injection. Further, a male screw 22 may be threaded on the lower end of the spout 10 to fix the fitting cap 5 by screwing. In this case, the lower surface of the collar 11 can be pressed more strongly against the upper surface of the fitting cap 5, and the stability of the mounted state can be increased. Further, scales 23 ... May be formed on the peripheral surface of the tank 4 so that the amount of the poured coolant and the amount of the coolant to be replenished can be known.

Further, like the coolant injector 1 shown in FIG. 6, the tank 4 may be formed of a synthetic resin sheet. In this case, it is advisable to provide the upper end of the tank 4 with a hanger 24 of a predetermined length that is hung on an open hood (not shown).

The fitting cap 5 does not have a tapered cone shape as in the previous embodiment, but has a shape having a plurality of stages of fitting portions 25 ... Corresponding to a plurality of types of filler ports 3 as shown in FIG. Good.
