Definitions
- the invention relates to a ventilation device on containers, in particular to Dieselkraftstoff sometimesem.
- Refueling vent devices provided. Depending on the type of fuel, gaseous hydrocarbons accumulate in a fuel tank due to heating and / or surging of the fuel. These gaseous hydrocarbons are purified via a fuel vapor filter, the purified gas is then released to the atmosphere. When removing fuel from the container, the volume of liquid removed from the container must be replaced by a corresponding volume of gas, that is, it must be possible for a corresponding amount of air to flow into the container. To regulate the ventilation of the container during operation of the vehicle usually fuel tank with the fuel vapor filter upstream valves are provided. In order to prevent the fuel running out in the event of a rollover, so-called rollover valves are either provided in addition, or the existing ventilation and venting valves cover this functionality.
- the hitherto known ventilation devices on fuel tanks are designed for the use of highly volatile gasoline fuels, where it should be avoided if possible that gaseous or even liquid hydrocarbons reach the atmosphere.
- the ventilation devices are often also connected with valves so that as little ambient air enters the container to inhibit the evaporation of fuel.
- the known technology is also used predominantly for diesel fuel tanks, although the complex valve technology, which is not required at the much lower volatilization tendency of the diesel fuel. Nevertheless, it is important here to prevent leakage of liquid hydrocarbons, for example, in the event of rollover.
- the invention is therefore an object of the invention to provide a particularly simple ventilation device to containers, especially to diesel fuel tanks, with the reliable escape of liquid is prevented, but at the same time with the simplest possible means a ventilation of the container is possible.
- a ventilation device on containers, in particular diesel fuel tanks, with a container opening covering or inserted into this closure body which is positively or materially connected to the container wall, for example, welded, glued or screwed in this wherein the closure body is designed as a gas-permeable, oleophobized and / or hydrophobized and largely liquid-impermeable porous body and wherein the ventilation device further comprises no moving parts and / or line connections or the like.
- Such a ventilation device is particularly easy to implement and takes over without moving parts, the functionalities ventilation and the functionality of a rollover valve in vehicle rollover.
- the valve functionalities are depicted without the need for moving components.
- the ventilation device according to the invention consists exclusively of the preferably integrally formed, an opening in the container wall covering closure body.
- the closure body consists of sintered plastic.
- This can for example consist of UHDPE (ultra high density polyethylene).
- the container is at least partially made of a plastic which is compatible with the plastic of the closure body in so far that the closure body is welded to the container.
- the container may for example consist of a coextruded laminate of plastic and be produced by extrusion blow molding.
- the Shell of the container made of HDPE (high density polyethylene), which is readily weldable with UHDPE.
- the closure body may, for example, have been oleophobized by fluorination or sulfonation. Since no separate surge protection is provided for the closure body of the ventilation device according to the invention, the oleophobization and / or hydrophobization of the same is so important as to prevent that the gas permeability is impaired by fuel and / or water contact.
- the closure body may simply be formed as a cap or cover, which is welded to the outer wall of the container edge. This may have been connected to the container, for example, by heating element welding / mirror welding or friction welding.
- the closure body comprises a thread which is screwed to a corresponding threaded portion of the container opening.
- the container opening may have a circumferential closure collar which cooperates with an internal thread of the closure body designed as a closure cap.
- Figure 1 is a schematic view of a container with a ventilation device according to the invention
- Figure 2 is an enlarged partial section of the area Il in Figure 1 and Figure 3 shows an alternative embodiment of the closure body shown in Figure 2.
- the dargestelle in Figure 1 container 1 is designed as a fuel tank for diesel fuel. 2 with a provided on this filler pipe is called.
- the invention is to be understood that the ventilation device according to the invention does not necessarily have to be realized on a fuel tank, but it is also possible, for example, to realize this on a windshield washer or a coolant reservoir.
- the air in the tank When filling a windscreen washer tank with cleaning liquid, the air in the tank must be displaced to the environment in a short time. If the venting accomplished by the filling, it comes through the outflowing air in conjunction with the inflowing water often to turbulent disturbances. The result of this is a buzzing sound and a Nachaussenspritzen the liquid during filling.
- the container 1 has a ventilation opening 3, which is covered with a closure body 4.
- This closure body 4 is formed in the case of dargestellen in Figure 2 embodiment as a plate.
- the closure body 4 is designed as a cap.
- the closure body 4 is formed as a porous sintered body of UHDPE (ultra high density polyethylene), which is oleophobized and hydrophobicized. This is gas permeable, but liquid impermeable.
- UHDPE ultra high density polyethylene
- the wall 5 of the container 1 at least on the outside of HDPE (high density polyethylene).
- the closure body 4 is welded to the wall 5 of the container 1.
- the ventilation device thus formed comprises no further moving parts and no lines or connections. Through the porous closure body 4, a gas exchange between the container interior and the atmosphere take place. Liquid leakage is prevented under normal pressure and temperature conditions.
- the ventilation device according to the invention may be provided at any suitable point of the container wall.
- the ventilation device according to the invention can also close a ventilation opening in the wall of the filler pipe. This is particularly useful when the ventilation device should be arranged in the car so that contamination by external influence should be avoided. In particular, in fuel tanks on off-road vehicles such an arrangement is conceivable. It is advantageous if the closure body is releasably and replaceably inserted into the wall of the filler pipe.
