Abstract

A cartridge for replenishing a vehicle fluid, a fluid reservoir system comprising same and a holder, a holder, a vehicle engine comprising the fluid reservoir system and a vehicle comprising said engine in which, the cartridge comprises: a housing comprising a first part and a second part; a fluid reservoir in the housing; a port arranged on the first part of the housing to couple the reservoir in fluidic communication with a fluid system of the vehicle; wherein the second part of the housing is configured to rotate with respect to the first part of the housing to secure the cartridge with respect to the fluid system to hold the reservoir in fluidic communication, via the port, with the fluid system of the vehicle, wherein the second part of the housing is configured such that rotating the second part of the housing does not rotate the port.

First claim

The invention claimed is:

1. A cartridge for replenishing a vehicle fluid, the cartridge comprising:
a housing comprising a first part and a second part;
a fluid reservoir configured to hold the vehicle fluid, wherein the fluid reservoir is in the housing; and
a port arranged on the first part of the housing to couple the fluid reservoir in fluidic communication with a fluid system of a vehicle;
wherein the second part of the housing is configured to rotate with respect to the first part of the housing to secure the cartridge with respect to the fluid system to hold the fluid reservoir in fluidic communication, via the port, with the fluid system of the vehicle, and wherein the second part of the housing is configured such that rotating the second part of the housing does not rotate the port.

2. The cartridge of claim 1 , wherein the first part of the housing and the second part of the housing cooperate to enclose the fluid reservoir.

3. The cartridge of claim 1 wherein the second part of the housing comprises one of a turret, a cuff, and a cap carried by the first part of the housing.

4. The cartridge of claim 1 , wherein the second part of the housing comprises a recess and a bar across the recess to provide a handle for rotating the second part of the housing and removing the cartridge from the fluid system.

5. The cartridge of claim 1 , wherein the cartridge comprises a deployable lug arranged to be deployed from the cartridge to secure the cartridge with respect to the fluid system in response to rotation of the second part of the housing.

6. The cartridge of claim 1 , wherein the first part of the housing has an asymmetric configuration configured to control orientation of the cartridge with respect to the fluid system when, in use, the port is in fluidic communication with the fluid circulation system.

7. The cartridge of claim 6 , wherein the asymmetric configuration comprises a key configured to engage with a feature of a holder for the cartridge.

8. The cartridge of claim 1 , wherein the second part of the housing is configured to provide a bayonet fitting which is operable to secure the cartridge with respect to the fluid system by rotating the second part of the housing with respect to the first part of the housing.

9. The cartridge of claim 1 , wherein the housing is arranged to be received by a holder on an engine, and the second part of the housing is configured to rotate to engage with the holder to secure the cartridge with respect to the fluid system and to hold the fluid reservoir in fluidic communication with the fluid system.

10. The cartridge of claim 1 , wherein the second part of the housing is configured to rotate through less than 360 degrees with respect to the first part of the housing to secure the cartridge with respect to the fluid system to hold the fluid reservoir in fluidic communication, via the port, with the fluid system by rotating the second part of the housing.

11. The cartridge of claim 1 , wherein the port comprises a releasable self-sealing port.

12. The cartridge of claim 1 in which the fluid reservoir contains vehicle fluid and the vehicle fluid comprises engine lubricating oil composition, heat exchange fluid for an electric engine, de-icer, water, screen-wash or detergent.

13. A holder for coupling a fluid cartridge to a vehicle, the holder comprising:
a connector for providing fluidic communication between a fluid port of the cartridge and a fluid system of the vehicle;
and being adapted to receive a cartridge in accordance with claim 1 , wherein when the second part of the housing is rotated with respect to the first part of the housing, the cartridge is secured with respect to the fluid system and holds the fluid reservoir in fluidic communication, via the port, with the fluid system of the vehicle, and wherein the second part of the housing is configured such that rotating the second part of the housing does not rotate the port.

14. The holder of claim 13 wherein the connector comprises:
a fluid return coupling configured to couple a fluid return line of a fluid system of a vehicle to an inlet port of the cartridge;
a fluid supply coupling configured to couple a fluid supply line of the fluid system to an outlet port of the cartridge; and
a vent coupling configured to couple a pressure control line of the fluid system to a vent port of the cartridge for controlling pressure in the fluid reservoir of the cartridge.

15. A fluid reservoir system comprising a cartridge for replenishing a fluid in an apparatus, the cartridge comprising:
a housing comprising a first part and a second part;
a fluid reservoir configured to hold the fluid, wherein the fluid reservoir is in the housing; and
a port arranged on the first part of the housing to couple the fluid reservoir in fluid communication with a fluid system of the apparatus;
wherein the second part of the housing is configured to rotate with respect to the first part of the housing to secure the cartridge with respect to the fluid system to hold the reservoir in fluidic communication, via the port, with the fluid system of the apparatus, and wherein the second part of the housing is configured such that rotating the second part of the housing does not rotate the port.

16. The fluid reservoir system of claim 15 further comprising a holder for coupling the cartridge to the apparatus, the holder comprising:
a connector for providing fluidic communication between a fluid port of the cartridge and the fluid system of the apparatus;
and being adapted to receive the cartridge,
wherein when the second part of the housing is rotated with respect to the first part of the housing, the cartridge is secured with respect to the fluid system and holds the fluid reservoir in fluidic communication, via the port, with the fluid system of the apparatus, and wherein the second part of the housing is configured such that rotating the second part of the housing does not rotate the port.

17. The fluid reservoir system of claim 15 further comprising a holder adapted to cooperate with the second part of the housing to secure the port in fluidic communication with the fluid system of the apparatus.

18. The cartridge of claim 1 , wherein the cartridge comprises a first end and a second end opposite the first end, wherein the port is arranged on the first part of the housing at the first end, and wherein at least a portion of the second part of the housing is arranged at the second end.

19. The cartridge of claim 1 , wherein the port comprises a valve.

20. The cartridge of claim 4 , wherein the first part of the housing comprises a first face, wherein the second part of the housing comprises a second face opposite the first face, wherein the port is arranged on the first part of the housing at the first face, and wherein the handle is arranged at the second face.

21. The cartridge of claim 5 further comprising an actuator between the second part of the housing and the deployable lug, wherein the actuator deploys the deployable lug in response to rotation of the second part of the housing.
