The cock comprises a block provided with a tang for coupling to an upper portion of a container of gas. This is associated with the upper end of a tubular body which supports an element for the detection of the level of the liquefied gas accommodatable within the container and operatively connected to a level display associated with the block. In the block there is provided a vent channel communicating with the interior of the container and with the outside and provided with a valve which can be operated from outside. The tubular body is provided, along its length, with at least one opening arranged at a level corresponding to a degree of filling preset by the container. The tubular body defines a channel for the connection of the opening to the vent channel. |
