Description

The invention relates to a fluid trough for collecting liquids, such as lubricant, such as oil, or fuel, such as diesel or gasoline, in a motor vehicle, with a housing in which a partition divides the interior of the housing into a collecting space and a residual space / spray space, wherein at least one line for bringing the liquid between the collecting space and the remaining space is present in the dividing wall.

The solutions known from the prior art have disadvantages which should be eliminated. In the prior art, for example, there is backflow through holes in partition walls, the holes functioning as guide elements and throttles and preventing the oil from flowing away. In this context there are swell plates / oil guide elements, labyrinth components, channel guides, throttles (plates) and other solutions. However, these solutions are usually complex and / or expensive and / or not very effective. The invention intervenes to improve this.

The object mentioned at the beginning is achieved according to the invention in a generic fluid trough in that (when viewed in the non-pivoted state, i.e. in the normal state) an inlet of the line assigned to the remaining space is offset in the direction transverse to gravity from an outlet of the line assigned to the collecting space.

As a result, a labyrinth-like liquid feed, for example an oil feed, is provided, which ensures that a backflow is prevented. Ultimately, a channel structure is introduced, which causes optimization in the case of different inclines. Such a dividing wall can be skillfully created by original shaping or by connecting two shells. The labyrinth structure can also be inserted / attached several times.

Advantageous embodiments are claimed in the subclaims and are explained in more detail below.

It is therefore advantageous if the partition is (exactly or at least) essentially (in particular in the normal operating state) aligned horizontally. If tilting occurs, the labyrinthine line section between the inlet and the outlet acts like a siphon. Efficient retention of the liquid is thus guaranteed. The liquid present in the collecting space can then poorly reach the remaining space in the inclined position, whereas the amount of liquid to be discharged in the remaining space in the direction of the collecting space can actually flow away through the line. It is advantageous if the length of the line and the beginning of the inlet as well as the end of the outlet are coordinated in such a way that an undesired return of the liquid into the remaining space is prevented, even under unfavorable operating conditions.

It has also proven useful when there are a large number of lines. As a result, the amount of liquid to be transported can be selected to be particularly high.

If all or some lines are aligned parallel to one another or are aligned transversely to one another, an advantageous embodiment can be implemented.

It has also been found to be advantageous if the inlets and outlets of two lines are positioned directly next to one another.

An advantageous embodiment is also characterized in that the length of all lines or some lines is the same.

For efficient liquid guidance, it is advantageous if some or all of the lines run perpendicular to the edge of the partition. The surface of the partition can then be used efficiently.

If the lines follow the circumference of the partition in their distribution, a particularly large number of lines can be used.

It is advantageous if a line section forms a siphon between the inlet and outlet.

In order to ensure that the invention is suitable for practical use, it is advantageous if the fluid sump is designed as an oil sump or fuel tank.

For production, it is particularly advantageous if the partition is designed as an injection-molded component, preferably made of plastic.

The invention is explained in more detail below with the aid of a drawing. Three embodiments of the invention are shown.

The figures are merely of a schematic nature and are only used for understanding the invention. The same elements are provided with the same reference symbols.

In 1 a first embodiment of a fluid tub according to the invention is shown. It is intended to collect liquids, namely oil. It is prepared for use in a motor vehicle. It has a housing 2 in which a partition 3 is used. It divides the interior 4th in a collecting room 5 and a rest room 6th on.

Inside the partition 3 is a line 7th available. The administration 7th has an enema 8th and an outlet 9 . Seen in the direction of gravity, the inlet is aligned 8th and the outlet 9 not. They are offset across it. Between the enema 8th and the outlet 9 there is a link 10 . The link 10 is aligned horizontally in normal operating condition.

In a state deviating from the normal operating state, but in an otherwise normal operating state, tilting occurs, as shown in FIG 2 is shown. The liquid level of the liquid 12th changes. Due to the siphon-like nature or the labyrinth-like course of the line 7th , seen from the enema 8th over the link 10 to the outlet 9 , but prevents unwanted backflow of the liquid from the collecting space 5 in the rest of the room 6th . The liquid level 11 determines the oil level and vice versa. In the state of 1 is a collection of oil on the surface of the partition 3 , namely on the side of the remaining space 6th indicated, with a flowing in along the arrows 13th in the collecting room 5 into it, takes place. A further optimization for different inclines enables the embodiment according to the 3 and 4th .

The circumferential attachment of a multitude of lines as seen over the circumference 7th is also the 5 and 6th refer to. Here are the lines 7th Arranged in four rows, with two rows facing the same direction on opposite sides of the partition 3 are formed and the other two rows across it on the remaining opposite sides of the partition 3 are trained.
