ABSTRACT:
An automatic water supply device for animals or plants, which uses a siphon tube for transferring a batch of water from a vessel having a float-valve type water inlet control device to a tray. The water transferring operation of the siphon tube is triggered by the water head applied to the siphon's outlet end and by the water received in the tray being reduced by a predetermined amount due to reduction of water level in the tray. The inlet tube portion of the siphon tube located in the internal space of the vessel has a diverged open end having an opening area which is substantially larger than that of the outlet tube portion of the siphon tube.
