AUTOMATIC DRINKING TROUGH FOR BREEDING BIRDS

摘要

An automatic drinking trough (10) for breeding birds, comprising valve means (30) arranged along a water supply channel (12) and at least one bowl (20) for collecting the water delivered through the valve means, is described. The drinking trough further comprises a drive assembly (40) having a lever member (41) and a tubular actuator (50) integral with the lever member, suspended at the center of the bowl (20). A movable piston (51) is placed between the valve means (30) and the lever member (41) in the drive assembly (40) for intercepting or delivering the flow of water depending on the inclination taken by the lever member (41).
