HThe float 51 should be so positioned, by bending
the rod 56, so that the maximum water levelwithin
the tank Iû is approximately as indicated by the
dotted lineas-#œ of Figure 2. When> the water
level within the tank is at this position, the float 51,
floating upon the surface of the water, maintains
the valve 49 closed Iby forcing the piston d8 to its

be opened at any time when the supply of water 40

development of syphonic conditions which other

the arm 5I causes the finger 58 and head 5I to
rotate in a clockwise direction as viewed upon
Figure 3, throughout a distance sufficient to move
the piston 43 to the right far enough to unseat
the diaphragm ¿i2 from the seats 38 and 39. This
movement of the head 5| also causes the float 51
to move downwards, submerging the float 51
within the water in the tank l0. Unseating the
diaphragm 42 from the seat 38 permits water to
flow from the supply pipe 29 through the tubular

The major portion of the water thus delivered

through which an extension 13 of the screw 19
`extends with a suliicient degree of looseness to

with respect to the lug 1I. However, the extent
of such movement is limitedby a coil spring 15
which is under compression between the lug 12
and a shoulder 1li formed on the screw 19. By
adjustment of the screw 19 the degree of com
pression of the spring 15 can be regulated, thereby
making possible variation oi the distance through
which the rocking head 5I can rotate in response
to downward movement of the iioat 51. In this
manner, the degree of opening of the valve 40
can be Vregulated so as to determine the velocity
