Animal drinking troughs have pressure reducers for reducing the higher pressure of the liquid supply to a low liquid pressure for supplying the animal drinking troughs. For various reasons, it is desired to change the reduced pressure. This takes place by adjustment of the pressure reducers. It is known to undertake such an adjustment with compressed air. This requires a separate compressed air source and a corresponding pipe system. The invention makes provision to adjust the pressure reducer hydraulically by means of the higher pressure of the liquid of the liquid supply. The energy required for adjusting the pressure reducers thereby provides the liquid pressure of the liquid supply. As a result, the pressure reducers according to the invention operate autonomously. A separate energy source for adjusting the pressure reducers is not required.

Pressure reducer for animal drinking troughs, and method for adjusting at least one pressure reducer for animal drinking troughs

An animal drinker allowing for the circulation of the water in the animal drinker. To this end, the animal drinker has two parallel pipe strings () that form a water circuit ensuring a constant movement of water, namely that water flows continuously through the pipe strings () even when no water has been removed at the drinking valves () over an extended period of time.

Linear water circulating animal drinker

A drinking trough having a drinking valve assigned to a water-supply line, the drinking valve having a valve pin that moves in order to discharge water; a water-collecting bowl assigned to the respective drinking valve; an actuating means or elongated actuating end of the valve pin extending from the valve pin to a water-accommodating hollow of the water-collecting bowl, the actuating means being movable between an actuated position to an unactuated position; and a starter body assigned to the respective water-collecting bowl, in which the starter body actuates the actuating means by moving the actuating means to the actuated position when water in the water-collecting bowl reaches a certain lower level, whereby the moving of the actuating means to the actuated position actuates the valve pin so as to allow water to flow from the drinking valve into the water-collecting bowl, and when the water in the water-collecting bowl reaches a certain higher level, the actuating means moves to the unactuated position, whereby the moving of the actuating means unactuates the valve pin so as to cease the flow of water from the drinking valve.
