Abstract

A fluid containment system includes a container, a sensor, and a splash shield. The container has a bottom and defines an interior configured for holding a volume of fluid. The volume of fluid is variable between a low volume range and a filled range. The sensor is operatively disposed in the interior of the container in spaced relationship to the bottom. The sensor is configured to be at least partially submerged in the fluid only when the volume is in the filled volume range. The splash shield is operatively disposed within the interior of the container at a barrier level defined between the sensor and the bottom. As such, the splash shield is disposed between the sensor and a surface level of the fluid when a level of the fluid is less than the barrier level to provide a barrier to prevent fluid from splashing onto the sensor.

First claim

The invention claimed is:

1. A fluid containment system comprising:
a container having a bottom;
wherein the container defines an interior configured for holding a volume of fluid;
wherein the volume of fluid is variable between a low volume range and a filled volume range;
a sensor operatively disposed in the interior of the container in spaced relationship to the bottom;
wherein the sensor is configured to be at least partially submerged in the fluid only when the volume is in the filled volume range; and
a splash shield operatively disposed within the interior of the container at a barrier level defined between the sensor and the bottom such that the splash shield is disposed between the sensor and a surface level of the fluid when a level of the fluid is less than the barrier level to provide a barrier to prevent the fluid from splashing onto the sensor;
wherein the splash shield includes a barrier section extending longitudinally to a distal end;
wherein at least a portion of the barrier section is operatively disposed at the barrier level;
wherein the barrier section includes a first surface and a second surface, opposite the first surface;
wherein the barrier section is configured to provide a barrier between the sensor and the fluid when the surface level of the fluid is less than the barrier level; and
wherein the barrier section has a semi-circular cross-sectional shape defining a channel.

2. A fluid containment system, as set forth in claim 1 , wherein the sensor is configured to sense a physical property of the fluid.

3. A fluid containment system, as set forth in claim 2 , wherein the sensor is configured to sense that the volume of fluid within the container is one of the low volume range and the filled volume range.

4. A fluid containment system, as set forth in claim 3 , wherein the sensor is a fluid level sensor including a housing and a float operatively supported by the housing;
wherein the float is configured to float in the fluid such that the float moves relative to the housing when the volume is in the filled volume range.

5. A fluid containment system, as set forth in claim 1 , wherein at least a portion of the splash shield is disposed at the barrier level in spaced relationship to the sensor such that a gap is defined between the barrier level and the sensor.

6. A fluid containment system, as set forth in claim 5 , wherein the gap is between 1 millimeter and 25 millimeters.

7. A fluid containment system, as set forth in claim 1 , wherein the barrier section defines at least one opening between the first surface and the second surface such that the at least one opening allows fluid to flow through the barrier section.

8. A fluid containment system, as set forth in claim 1 , wherein at least a portion of the sensor partially extends into the channel.

9. A fluid containment system, as set forth in claim 1 , wherein the splash shield further includes an attachment section;
wherein the barrier section longitudinally extends generally perpendicularly from the attachment section to the distal end;
wherein the attachment section defines a slot; and
wherein the sensor is received within the slot such that the splash shield is operatively attached to the sensor.

10. A vehicle comprising:
a controller; and
a fluid containment system in operative communication with the controller; the fluid containment system including:
a container having a bottom;
wherein the container defines an interior configured for holding a volume of fluid;
wherein the volume of fluid is variable between a low volume range and a filled volume range;
a sensor operatively disposed in the interior of the container in spaced relationship to the bottom;
wherein the sensor is configured to be at least partially submerged in the fluid only when the volume is in the filled volume range;
wherein the sensor is operatively connected to the controller and configured to transmit a signal to the controller when the sensor detects the volume is in the low volume range; and

a splash shield operatively disposed within the interior of the container at a barrier level defined between the sensor and the bottom such that the splash shield is disposed between the sensor and a surface level of the fluid when a level of the fluid is less than the barrier level to provide a barrier to prevent the fluid from splashing onto the sensor;
wherein the splash shield includes a barrier section extending longitudinally to a distal end;
wherein at least a portion of the barrier section is operatively disposed at the barrier level;
wherein the barrier section includes a first surface and a second surface, opposite the first surface;
wherein the barrier section is configured to provide a barrier between the sensor and the fluid when the surface level of the fluid is less than the barrier level; and
wherein the barrier section has a semi-circular cross-sectional shape defining a channel.

11. A vehicle, as set forth in claim 10 , wherein the sensor is a fluid level sensor including a housing and a float operatively supported by the housing;
wherein the float is configured to float in the fluid such that the float moves relative to the housing when the volume is in the filled volume range.

12. A vehicle, as set forth in claim 10 , wherein at least a portion of the splash shield is disposed at the barrier level in spaced relationship to the sensor such that a gap is defined between the barrier level and the sensor.

13. A vehicle, as set forth in claim 12 , wherein the gap is between 1 millimeter and 25 millimeters.

14. A vehicle, as set forth in claim 10 , wherein the barrier section defines at least one opening between the first surface and the second surface such that the at least one opening allows fluid to flow through the barrier section.

15. A vehicle, as set forth in claim 10 , wherein at least a portion of the sensor partially extends into the channel.

16. A vehicle, as set forth in claim 10 , wherein the splash shield further includes an attachment section;
wherein the barrier section longitudinally extends generally perpendicularly from the attachment section to the distal end;
wherein the attachment section defines a slot; and
wherein the sensor is received within the slot such that the splash shield is operatively attached to the sensor.

17. A fluid containment system comprising:
a container having a bottom;
wherein the container defines an interior configured for holding a volume of fluid;
wherein the volume of fluid is variable between a low volume range and a filled volume range;
a sensor operatively disposed in the interior of the container in spaced relationship to the bottom;
wherein the sensor is configured to be at least partially submerged in the fluid only when the volume is in the filled volume range; and
a splash shield operatively disposed within the interior of the container at a barrier level defined between the sensor and the bottom such that the splash shield is disposed between the sensor and a surface level of the fluid when a level of the fluid is less than the barrier level to provide a barrier to prevent the fluid from splashing onto the sensor;
