Definitions

• the invention relates to a device for ventilation of a liquid container, which by a protruding into the container in the mouth of the filling or. Emptying opening angled line sections of a removable ventilation device having an air line is formed.
• Devices of this type are used, for example, on liquid containers for the transport, storage and provision of operating resources of all kinds, such as fuels, oils or the like, foods, additives, etc. Repair and maintenance companies for vehicles, machine tools and work machines, mechanical workshops, construction and manufacturing companies in the metalworking industry are particularly affected by the handling of such liquids.
• a liquid container has become known from CH-A-537308, in which on the inside of the filling or. Emptying nozzle at least one molded retaining strip is provided for receiving the ventilation line by means of a complementarily designed holding groove, such that the ventilation line can be pushed onto the retaining strip.
• the filling or. Emptying the ventilation line removed and thus the accessibility to the container space can be improved.
• this object is achieved in that the line section of the ventilation device, which connects to the line section communicating with the environment, extends into one of the filling or. Discharge opening extends further away, located under the upper container wall container area.
• This technical measure makes it possible for atmospheric ambient air to enter the container when it is emptied, in particular into the small cavity in the upper region of the container which initially forms due to the initial inclination of the liquid container or to flow in from the surroundings.
• the vacuum in the container caused by the outflow of the liquid can be compensated for by the resulting suction effect in the environment via the line sections by supplying air into the container area or cavity of the liquid container.
• the container area can by side walls respectively. in the case of cylindrical containers, be formed by the container jacket and the upper container wall.
• the container region is formed by a bead-like elevation, so that when emptying from the beginning in the liquid container, an air supply in the container region or cavity, which increases due to the outflow of the liquid, promotes an effect can stand.
• the shut-off valve is preferably designed with a floating body, which is designed as a shut-off element and faces the liquid and is displaced by the liquid against a valve seat when the container is full.
• the shut-off element is spherical or conical and has a lower specific weight than the liquid which generates a buoyancy;
• a spherical shut-off device does not require any special guidance due to its regular shape.
• the shut-off device can be in a preferably cage-like housing, which on the one hand has an inlet opening for the liquid acting on the shut-off device and on the other hand is connected to the line section of the ventilation device or the environment protruding into the container, from a valve open position to a shooting range ment to be movably arranged on the valve seat.
• connection of the line sections is expanded, so that at most a small amount of liquid entering via the shut-off valve can flow out more easily via the ventilation device.
• the line section adjoining the shut-off valve has an inclined position acting towards the connection point.
• the housing is arranged so that the Direction of movement of the shut-off element to the valve seat and the line section adjoining it at least indirectly form an acute angle ⁇ .
• the line section communicating with the environment is advantageously connected to the inner wall of a pouring sleeve designed as an emptying nozzle, which from the outside into the filling or. Emptying opening of the container is designed to be insertable and lockable, as a result of which the ventilation device can be used universally.
• the line section facing the environment is designed to be closed within the emptying nozzle, but points in the direction of the emptying nozzle or of the pouring sleeve separately outward openings.
• a partition that is segment-like along the length of the line section in the pouring spout and is tightly connected on its side edges to the inner wall of the pouring spout, the air passage openings being provided in the pouring spout in the region of the dividing wall.
• the partition wall itself of the line section closed at the end could also be formed by a tube, which could also be slotted in the longitudinal direction, which is tightly fastened to the inner wall of the pouring sleeve.
• the pouring sleeve or the emptying nozzle is bent in the direction of inclination of the container to be emptied.
• direction is preferably a closure cap which can be pushed onto the emptying nozzle.
• Emptying opening of the container preferably takes place in that the pouring sleeve by means of an annular union nut on the filling or. Emptying opening can be screwed down in a supporting manner, a screw connection known per se which has proven itself for such purposes and can form a tight connection.
• FIG. 1 shows a longitudinal section through a container provided with a ventilation device according to the invention
• FIG. 2 shows a cross section along the line II-II in FIG. 1.
• FIG. 1 shows a container 1 in the upper area, which is provided for holding a liquid 2.
• the liquid level is in the vicinity of the upper container wall 3.
• Such handles are known and need no further description.
• the container 1 also has a filling or. Emptying opening 4, which is arranged in the upper container wall 3 near a lateral end. In order to be able to close the container 1, the filling or. Drain opening 4 an external thread 6 on which a screw closure (not shown) can be screwed on.
• the container 1 is prepared for emptying and in the filling or.
• Emptying opening 4 a ventilation device is installed, which by an annular union nut 25 on the external thread 6 on the filling or. Emptying opening 4 is clamped.
• annular shoulder 8 is attached to a pouring sleeve 7 of the ventilation device 5, which shoulder at the edge of the filling or. Emptying opening 4 rests.
• line sections 9, 10 of the ventilation device 5 via which air from the environment into the container area 11 or. a cavity of the liquid container 1 is guided, line section 9 communicating with the atmospheric environment and line section 10 projecting into the container area or cavity 11.
• the latter is more distant from the filling or Emptying opening 4 and is formed by the upper container wall 3 and three side walls of the container 1.
• the container region or cavity 11 has a bead-like elevation 12.
• the line section 10 extending into this container area or cavity 11 is angled and connected to the line section 9 facing the surroundings. At least line section 10 has a line cross-section which increases progressively towards the enlarged connection point 13.
• the end of the line section 10 which extends towards the container area or cavity 11 is formed with a shut-off valve 14 which can be actuated by the liquid 2.
• This consists of a shut-off element 16 which is movably guided in a housing 15 and is spherical and has a lower specific weight than the liquid 2, which in turn presses the shut-off element 16 designed as a floating body against a valve seat 17 of the housing 15 and thereby blocking the entry of liquid into the ventilation device 5.
• the container area or cavity 11 flows into the container area or cavity 11 due to a vacuum developed in the container area 11 due to the emptying, air from the environment via the ventilation device 5 when the shutoff element 16 is lifted off the valve seat 17 and for a smooth outflow of the Ensure liquid at the pouring spout 7.
