Vented degas bottle for motor vehicle coolant system
A degas bottle for a motor vehicle coolant system is provided. The degas bottle has a body defining an enclosed cavity bounded by an upper wall, a lower wall and a side wall extending between said upper and lower walls. An inlet extends into an upper region of the cavity proximate the upper wall and an outlet extending outwardly from a lower region of the cavity proximate the lower wall. An interior wall is disposed in the enclosed cavity. The interior wall extends from the upper wall toward the lower wall to a free end spaced from the lower wall. The interior wall has a vent opening proximate the upper wall and extends to the side wall on opposite sides of the inlet. A baffle is disposed between the interior wall and the inlet. The baffle extends from one of the upper wall or the lower wall to a free end spaced from the other of the upper wall or the lower wall.
1. A degas bottle for a motor vehicle coolant system, comprising:
a body having an enclosed cavity bounded by an upper wall, a lower wall and a side wall extending between said upper and lower walls;
an inlet extending into an upper region of said cavity proximate said upper wall for receiving coolant into said enclosed cavity;
an outlet extending outwardly from a lower region of said cavity proximate said lower wall for discharging coolant from said enclosed cavity;
an interior wall disposed in said enclosed cavity, said interior wall extending toward said lower wall and having a free end spaced from said lower wall to separate an inlet chamber, into which coolant flows directly from said inlet, from an outlet chamber, from which coolant flows outwardly through said outlet; and
a baffle disposed in said inlet chamber between said interior wall and said inlet, said baffle extending lengthwise along an axis from one of said upper wall or said lower wall, said baffle being configured so that coolant flowing through said inlet impinges against said baffle and then flows beneath said free end of said interior wall and then through said outlet.
2. The degas bottle of claim 1 , wherein said baffle extends to a free end spaced from the other of said upper wall or said lower wall opposite the one of said upper wall or said lower wall from which said baffle extends.
3. The degas bottle of claim 2 , wherein said free end of said baffle is spaced from said upper wall.
4. The degas bottle of claim 1 , wherein said baffle is semi-tubular.
5. The degas bottle of claim 4 , wherein said baffle is generally C-shaped in cross-section taken along a plane extending transversely to said axis.
6. The degas bottle of claim 4 , wherein said baffle has opposite free edges extending generally parallel to said axis.
7. The degas bottle of claim 6 , wherein said inlet is generally aligned between said opposite free edges.
8. The degas bottle of claim 6 , wherein said opposite free edges are spaced from one another by a gap, said gap facing said inlet.
9. The degas bottle of claim 1 , wherein said baffle extends across said inlet.
10. The degas bottle of claim 1 , wherein said baffle is entirely spaced from said side wall and said interior wall.
11. The degas bottle of claim 1 , wherein said interior wall extends from said upper wall; and
wherein said interior wall defines a vent opening proximate said upper wall.
12. A degas bottle for a motor vehicle coolant system, comprising:
a body having an enclosed cavity bounded by an upper wall, a lower wall and a side wall extending between said upper and lower walls;
an inlet extending into an upper region of said cavity proximate said upper wall for receiving coolant into said enclosed cavity;
an outlet extending outwardly from a lower region of said cavity proximate said lower wall for discharging coolant from said enclosed cavity;
an interior wall disposed in said enclosed cavity, said interior wall extending from said upper wall and said side wall toward said lower wall to a free end spaced from said lower wall and separating an inlet chamber from an outlet chamber; and
a baffle disposed in said inlet chamber between said interior wall and said inlet, said baffle being configured so that coolant flowing through said inlet impinges against said baffle and then flows beneath said free end of said interior wall and then through said outlet.
13. The degas bottle of claim 12 , wherein said baffle is semi-tubular.
14. The degas bottle of claim 13 , wherein said baffle extends lengthwise along an axis between one of said upper wall and said lower wall, and wherein said baffle is generally C-shaped in cross-section taken along a plane extending transversely to said axis.
15. The degas bottle of claim 13 , wherein said baffle extends lengthwise along an axis between one of said upper wall and said lower wall, and wherein said baffle has opposite free edges extending generally parallel to said axis.
16. The degas bottle of claim 15 , wherein said inlet is generally aligned between said free edges.
17. The degas bottle of claim 15 , wherein said free edges are spaced from one another by a gap, said gap facing said inlet.
18. The degas bottle of claim 12 , wherein said baffle extends across said inlet.
19. The degas bottle of claim 12 , wherein said baffle is entirely spaced from said side wall and said interior wall.
20. The degas bottle of claim 1 , wherein said interior wall extends from said side wall of said body.
