由端にはフロート２６が取付けられている。 The casing 2 of the ball tap 1 has a generally shaped side profile, the inlet end 3 and the outlet end 4 being at right angles to each other. There is a valve seat 5 inside the casing 2.
The interior is divided into a primary flow path 6 and a secondary flow path 7 with the valve seat 5 as a boundary. The valve body abutting surface 5a of the valve seat 5 faces toward the secondary flow path 7, that is, toward the outlet end 4. A valve body 8 is provided vertically movably along the central axis of the valve seat 5, and this valve body 8 is located on the side of the main body 9 located on the side of the secondary side flow path 7 and on the side of the primary side flow path 6. It has a cylindrical guide portion 10. The main body 9 has a smooth convex curved peripheral wall 11 that reaches its maximum diameter at any point along its length (in the vertical direction), and is generally oval-shaped as a whole. The peripheral surface of the secondary flow path 7 is the main body 9
It has a concave curved circumferential surface corresponding to the shape of. A packing 12 is attached to the upper part of the guide part 10, and this packing 12 fits into the recess 1 of the casing 2.
It is slidably housed in 3. A slit 14 is formed at the lower end of the main body 9, and the slit 14 has a recess 15 into which a protrusion 17 at the free end of the valve body operating lever 16 is fitted.
This valve body operating lever 16 is pivotally mounted to a bracket 18 of the casing 2 so as to be vertically movable. In addition,
A notch 19 is formed near the outlet end 4 of the casing 2 to prevent vertical swinging of the valve body operating lever 16. Valve body operation lever 1
The lower side surface of the center in the longitudinal direction of 6 is a cam surface 20 that bulges downward toward the free end. A cam follower 21 made of a roller is in contact with this cam surface 20, and this cam follower 21
is rotatably attached to a pair of rocking pieces 23 that are constituent members of a float arm 22 arranged to sandwich it, and these rocking pieces 23 are rotatably attached to a bracket 25 of the casing 2 at the upper end. At the same time, it is prevented from rotating clockwise beyond a predetermined position. At the free ends of these swing pieces 23, so as to be sandwiched between them,
Shaft body 2 which is another component of float arm 22
4 is fixed and repositionable. It goes without saying that the swing piece 23 and the shaft body 24 may be integrated. Alternatively, the cam surface 20 may be formed on the swing piece 23 and the cam follower 21 may be formed on the valve body operating lever 16. A float 26 is attached to the free end of the shaft 24.
（実施例の作用） 次に実施例の作用について説明する。(Effect of Example) Next, the operation of the embodiment will be explained.

動的に停止する。 In the illustrated state, the float 26 is at the lowest position, so the cam follower 21 does not ride on the cam surface 20. Accordingly, since the valve body operating lever 16 is also in a state with its free end at the lowest position, the main body 9 of the valve body 8 is separated from the valve seat 5. In other words, the ball tap 1 is in the water supply state. When the water supply continues for a predetermined period of time and the water level rises, the float 26 is pushed up by the water, so the float arm 22
swings counterclockwise, the cam follower 21 rides on the cam surface 20, and the valve body operating lever 16 is rotated counterclockwise, so the valve body 8 rises and the main body 9 touches the valve body abutment surface 5a of the valve seat 5. The water supply will automatically stop due to the close contact with the
水面が下がればフロート２６が下がるので再び
給水が開始される。なお、弁体８をばねによつて
それが開く方向に付勢するようにしてもよい。 When the water level drops, the float 26 lowers and water supply starts again. Note that the valve body 8 may be biased in the direction of opening by a spring.
なお、弁体８は水平方向に移動させるようにし
てもよい。 Note that the valve body 8 may be moved in the horizontal direction.

のを防止することが出来る。(Effect of the invention) As described above, according to this invention, the secondary flow path 7
The main body 9 located on the side has a smooth convex curved circumferential wall 11 that reaches its maximum diameter in the middle of its length, and has no member protruding from the convex curved circumferential wall 11. Since there is no member such as a guide vane in the secondary flow path 7 that obstructs the flow therein, the flow inside the secondary flow path 7 is smaller than when there is a member such as a guide vane. Water can flow smoothly along the convex curved peripheral wall 11. In addition, the convex curved peripheral wall 11
Since the water flows along the flow direction, it is possible to prevent dust and the like from adhering to the main body 9.
