In addition, by rotating the lever 33 in two stages (reversely in the direction of arrow B) and releasing the tension on the cable 31, the plunger-type valve 36 is biased by the spring 3 and moves in two stages through the two passages 24 and 21. can be closed in sequence to stop the supply of liquid to the desired destination.

Still other embodiments of the switching cock of the present invention are shown in Figures 5a and 5b.
This is explained by Figure 5a is a cross-sectional plan view of the main part;
The figure is a vertical cross-sectional view taken along the line A-A in Figure A, in which 23 is a pipe in the other passage 21, 25 is a pipe in one passage 24,
28 is a pipe of the liquid passage 27. Plunger type valves 38, 38' are provided in parallel at the same level position in the other passage 21 and one passage 24, and the spring 3
9.39', the two passages 21.24 are closed.

A cable 40' connected to the outer end of the rod 38'a of the plunger type valve 38' provided in one passage 24 is connected to the rod 38'a of the plunger type valve 38 in the other passage 21.
The ends of both cables are connected to a tensioner 41, and the cable 40' of the plunger type valve 38' in one passage 24 is tensioned and lengthened by a spring 42. That is, cable 40
The fitting 43 at the connecting end of the plunger type valve 38' is slidably inserted into the hollow hole 44 provided in the rod 38'a of the plunger type valve 38', and the spring 42 is inserted to close the cap 45.
The spring 42 presses the metal fitting 43 against the inner end of the hollow hole 44 to tension the cable 40'. Connect one main cable 46 to the tensioning tool 41, and connect the tip of the main cable 46! As in the previous embodiment shown in FIG. 3, it is connected to a lever 33 attached to a support 32. Note that the casing of one plunger type valve 38 is longer than the casing of the other plunger type valve 38'.

In the switching cock of the embodiment shown in FIGS. 5a and 5b,
By rotating the lever 33 (see FIG. 3) attached to the support 32 in two steps in the direction of the arrow, the tensioner 41 is pulled via the main cable 46, and the cable 40.4 is pulled.
0' is pulled in two steps. In the first pulling operation of this two-step process, the cable 40 pulls the plunger-type valve 38 against the spring 39 to open the other passageway 21, while the cable 40' pulls the plunger-type valve 38 against the spring 42. Since the plunger-type valve 38' is slid within the hollow hole 44 of the rod 38'a, the plunger-type valve 38' is not pulled and one passage 24 remains closed. In the next pulling operation, cable 40' will pull plunger-type valve 38' against spring 39 to open one passageway 24. In this way, by sequentially opening the two passages 21 and 24 in two stages, the liquid from the liquid tank 26 (see FIG. 1) is transferred to the liquid passage 27 of the pipe 28 and the liquid pipe 35.
(See Figure 1) can be supplied to the required supply destination. By operating the lever 33 in the reverse direction in two steps in the direction of arrow B, the tension on the cable 40' is first released, and the plunger type valve 38' is biased by the spring 39.
closes one passageway 24, and then the tension on cable 40 is released, causing plunger-type valve 38, biased by spring 39, to close the other passageway 21. At this time, the cable 40' on the plunger-type valve 38' side of one passage 24 is tensed as a result of the metal fitting 43 at the connecting end being pressed against the inner end of the hollow hole 44 by the five springs 42.

In each of the above embodiments, the liquid tank 26 is a single tank.
This can also be applied to the case of 2 rites. That is, in the case of two liquid tanks 26' adjacent to each other on the left and right as shown in FIG. 6, and in the case of two liquid tanks 26'' stacked vertically as shown in FIG. 7, the type switching shown in FIG. A cock can be applied.Of course, a switching cock of the type shown in FIG. 5 can also be applied.

In either case, the passages 47 and 48 are closed and opened, but only the passage 48 cannot be opened. The passage 47 is opened first to supply liquid. These two liquid tanks 26'.

26'' may be filled with different liquids or may be filled with the same liquid.

A single plunger-type valve 49 is provided as a switching valve at the same level position in the middle of the passages 47 and 48, and is normally biased by a spring 37.
7.48 is closed. The plunger valve 49 is provided with narrow diameter portions 50.51 at two locations in the middle, and passages 47.48 are opened individually at the narrow diameter portions 50.51. That is, as shown in FIG. 8a, the spring 37
When the plunger type valve 49 is in the energized state, the passages 47 and 48 are both closed. As shown in FIG. 8, when the plunger type valve 49 is pulled against the spring 37 to position the narrow diameter portion 50 in the passage 47, the passage 47 is opened and the passage 48 remains closed. 8th
As shown in FIG. C, when the plunger type valve 49 is further pulled against the spring 37 to position the narrow diameter portion 51 in the passage 48, the passage 48 is opened and the passage 47 is closed.

The switching cock of this embodiment can be applied whether the liquid tank is a single-phase liquid tank or two or more liquid tanks. In the above case, the plunger type valve 49 opens from the passage 47 first.
However, the plunger type valve 49 may be arranged so that the passage 48 opens first. One liquid passage 52 connected to the passages 47 and 48 supplies liquid to the same location, but when supplying liquid to different locations,
There may also be two liquid passages connected to the passages 47 and 48, respectively.

Note that the narrow diameter portion 51 may be a groove or a hole.

(Effects of the Invention) As can be seen from the above explanation, the liquid tank switching cock according to the present invention is a plunger-type switching cock that can be operated via a cable by rotating a lever with at least one passage provided at a desired position. The valve can be opened by pulling it, and when the lever is operated in the reverse direction, the plunger-type valve is biased by a spring and closed, allowing remote control of supplying and stopping the liquid in the liquid tank, and simple operation by simply pulling. Open and close the switch cock and sew.

In particular, in the case where plunger-type valves are installed in two passages, the two passages can be opened in sequence by pulling the plunger-type valve via a cable through a two-step rotation operation of a lever installed at a desired position. By the two-step reversal operation, the plunger type valve is biased by the spring and the two passages are closed in the reverse order, making it easier to open and close the switching cock.

Therefore, various outdoor liquid tanks, various indoor liquid tanks, various equipment such as motorcycles that are transportation vehicles,
If applied to tanks for three- and four-wheeled motor vehicles, agricultural vehicles, warehouse vehicles, etc., the practical effects will be extremely large.
