Title:
PRESSURE REDUCER FOR ANIMAL DRINKING TROUGHS, AND METHOD FOR ADJUSTING AT LEAST ONE PRESSURE REDUCER FOR ANIMAL DRINKING TROUGHS
Document Type and Number:
WIPO Patent Application WO/2018/015002
Kind Code:
A8
Abstract:
Animal drinking troughs have pressure reducers (15) for reducing the relatively high pressure of the liquid supply to a low liquid pressure for supplying the animal drinking troughs. It is desired for various reasons to change the reduced pressure. This takes place by way of adjustment of the pressure reducers (15). It is known to perform an adjustment of this type by way of compressed air. This requires a separate compressed air source and a corresponding line system. The invention provides adjusting the pressure reducers (15) hydraulically by way of the relatively high pressure of the liquid of the liquid supply. As a result, the energy which is required to adjust the pressure reducers (15) supplies the liquid pressure of the liquid supply. As a result, the pressure reducers (15) according to the invention operate autonomously. A separate energy source for adjusting the pressure reducers (15) is not required.
