Abstract

The invention concerns an under opening automatic sluice with a cylinder shaped gate (1) tilting around a horizontal axis which is positioned in the centre of the shaft (3). The size of the opening of the gate is controlled by one or more floating counterweight(s) (17) which is (are) positioned in (a) housing(s) (18) and which is (are) in open connection with the upper or lower water level. Because the centre of gravity of the gate (1) changes place horizontally with the gate movement, it is possible to maintain a preadjusted level. By adjustment of the bow-formed cylinder wall (2) with respect to shaft (3) it is possible to influence the operation characteristic of the gate.
