WORKING MACHINE

Abstract

The present invention relates to a working machine having an engine room and a housing, wherein the housing at least partially surrounds or can surround the engine room, wherein a venting space, in which a line mouth of a line ends, is arranged on the housing, wherein the venting space is delimited from the engine room, preferably delimited in a gas-tight manner, and wherein the venting space is formed by a partial region of the housing and a bottom piece arranged in the engine room.

Claims

1. Working machine, comprising an engine room and a housing, wherein the housing at least partially surrounds or can surround the engine room, a venting space, in which a line mouth of a line ends, is arranged on the housing, the venting space is delimited from the engine room, preferably delimited in a gas-tight manner, and the venting space is formed by a partial region of the housing and a bottom piece arranged in the engine room.

2. Working machine according to claim 1, wherein the partial region comprises a component, preferably a box, mounted in the housing.

3. Working machine according to claim 1, wherein the housing comprises an opening connected or connectable to the venting space and covered by a grille or perforated plate arranged on or in the housing.

4. Working machine according to claim 1, wherein the venting space does not project outwardly from the housing.

5. Working machine according to claim 1, wherein the line mouth of the line is arranged at the bottom piece.

6. Working machine according to claim 1, wherein the line is an outgassing line, a hydrogen overpressure line or a vent line and/or the line mouth comprises a protective cap.

7. Working machine according to claim 1, wherein seals are arranged on the bottom piece and/or on the housing, which can effect the, preferably gas-tight, delimitation of the venting space with respect to the engine room.

8. Working machine according to claim 1, wherein the housing can be lifted or folded open and/or is a hood or casing.

9. Working machine according to claim 1, wherein the venting space allows a protective cap to be popped off or detached from the line mouth.

10. Working machine according to claim 1, wherein water present in the venting space can drain off via the bottom piece.

11. Working machine according to claim 1, wherein the housing comprises sheet metal and/or plastic material and/or a plastic composite material and/or a combination of materials.

12. Working machine according to claim 1, wherein the working machine comprises a fuel cell drive and/or a hydrogen reciprocating engine and/or a fuel system, in particular a hydrogen fuel system, for fuel present at least in sections in the gaseous state and/or the working machine is a mobile working machine.

13. Working machine according to claim 2, wherein the housing comprises an opening connected or connectable to the venting space and covered by a grille or perforated plate arranged on or in the housing.

14. Working machine according to claim 13, wherein the venting space does not project outwardly from the housing.

15. Working machine according to claim 3, wherein the venting space does not project outwardly from the housing.

16. Working machine according to claim 2, wherein the venting space does not project outwardly from the housing.

17. Working machine according to claim 16, wherein the line mouth of the line is arranged at the bottom piece.

18. Working machine according to claim 15, wherein the line mouth of the line is arranged at the bottom piece.

19. Working machine according to claim 14, wherein the line mouth of the line is arranged at the bottom piece.

20. Working machine according to claim 13, wherein the line mouth of the line is arranged at the bottom piece.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Further advantages, features and effects of the present invention will be apparent from the following description of preferred embodiments with reference to the figures, in which the same or similar components are designated by the same reference characters. The Figures show in:

[0038] FIG. 1: a sectional view of an embodiment of a working machine according to the invention.

[0039] FIG. 2: a sectional view of this embodiment of a working machine according to the invention from another perspective.

[0040] FIG. 3: a sectional view of this embodiment of a working machine according to the invention from another perspective.

[0041] FIG. 4: a partial view of this embodiment of a working machine according to the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0042] In FIG. 1, it can be seen that a hood 10 at least partially surrounds an engine room 1.

[0043] A bracket 13 is fixed in the hood 10. An indentation 11 is formed by the housing 10 and the console 13. Attached to the bracket 13 is a seal 4 that abuts a bottom piece 5. The bottom piece 5 is attached to or on a tank pan. Attached to the bottom piece 5 is another seal 4, which abuts the inside of the housing 10. The indentation 11 and the bottom piece 5 form a venting space with the seals 4. The indentation 11 is covered to the outside by a perforated plate 12 arranged on the hood 10. Gas can escape through the perforated plate 12. Reaching into the indentation 11 is prevented by the perforated plate 12.

[0044] FIG. 1 also shows that several lines 2 are routed through the bottom piece 5. The lines 2 end in line mouths. The bottom piece 5 can be attached to the lines 2.

[0045] Protective caps 3 are shown in a detached position from the line mouths to illustrate that indentation 11 provides enough room for protective caps 3 to detach or pop off.

[0046] The lines 2 may only protrude upwards from the bottom piece 5 to a certain height, and the bottom piece 5 preferably has a minimum distance to the housing 10, as otherwise the hood 10 cannot be opened.

[0047] FIGS. 2 and 3 show the arrangement of the mentioned elements again, each from a different perspective.

[0048] FIG. 4 shows the hood 10 of a working machine with an inwardly extending indentation 11, which has an opening to the outside. Protective caps 3 are arranged in the indentation 11 in a detached position.
