Abstract

An arrangement for removing water from mud and the like has a flexible container having an inlet and an outlet opening. A flexible tubular member is located outside and adjacent the outlet opening of the container. Means are provided for deforming the flexible tubular member so that the latter closes the outlet opening of the container during dewatering of the mud. The flexible tubular member may be formed either of a one piece with the container or as a separate part connected to a front end portion of the same. At least two ring-shaped elements are provided, one of which elements is connected to the front portion of the container, and the other element is connected to the flexible tubular member and rotatable relative to the first ring-shaped element. By means of rotation of the other ring-shaped element the flexible tubular member is deformed so as to close the outlet opening.
