Abstract

The present application relates to apparatus for mounting on a rotatable portion of a diesel filter for controlling a drainage valve. The apparatus comprises an outlet for draining liquid from the diesel filter, mounting apparatus for fixedly mounting the apparatus on the rotatable portion, and a manipulation portion for manipulation by a user's hand which projects, at least in part, radially outward from said rotatable portion, in use. The application also relates to a finger grip wheel for a diesel filter. The finger grip wheel has a drainage outlet and at least one finger detent for accommodating a tip of a user's finger to facilitate rotation of the finger grip wheel.

First claim

The invention claimed is:

1. A combination of:
a diesel filter comprising a rotatable portion for controlling a drainage valve, wherein the rotatable portion includes a drainage port through which liquid exits the rotatable portion in an axial direction substantially parallel to an axis of rotation of the rotatable portion, and wherein the rotatable portion is a thumbwheel of the diesel filter or the rotatable body portion of a water-in-fuel sensor; and
an apparatus for mounting on the rotatable portion, the apparatus comprising:
an outlet for draining liquid from the diesel filter, the outlet having an outlet aperture through which at least a portion of the drainage port of the rotatable portion extends, in use;
a mounting apparatus configured to fixedly mount the apparatus on the rotatable portion to restrict relative movement between the apparatus and the rotatable portion; and
a manipulation portion for manipulation by a user's hand, the manipulation portion projecting, at least in part, further outwards in a radial direction than said rotatable portion in order to facilitate rotation of the rotatable portion of the diesel filter, in use.

2. A combination according to claim 1 , wherein the mounting apparatus comprises at least one locating member.

3. A combination according to claim 2 , wherein one or more of the at least one locating members is a latching member for engaging a side of the rotatable portion.

4. A combination according to claim 2 , wherein a radially inwardly directed flange is provided on a distal end of one or more of the at least one locating members.

5. A combination according to claim 1 , wherein the mounting apparatus comprises at least one mechanical fastener.

6. A combination according to claim 5 , wherein the or each mechanical fastener is a grub screw.

7. A combination according to claim 1 , wherein the outlet comprises a nozzle for connection to the drainage port provided on the rotatable portion.

8. A combination according to claim 7 comprising a sealing member for forming a seal between the nozzle and the drainage port.

9. A combination according to claim 1 , wherein a drainage conduit is connected to the outlet.

10. A combination according to claim 1 , comprising a sensor aperture to enable connection of an electrical connector to a sensor in the diesel filter.

11. A combination according to claim 1 , wherein the manipulation portion comprises a wheel.

12. A combination according to claim 11 , wherein the wheel comprises a plurality of finger grip detents to facilitate rotation of the wheel.

13. A combination according to claim 12 , wherein the finger grip detents are formed around an outer circumference of the wheel.

14. A combination according to claim 11 , wherein the wheel locates over the rotatable portion.

15. A combination according to claim 1 , wherein the manipulation portion comprises a wheel, and wherein the wheel has a major diameter that matches a diameter of an outer casing of the diesel filter.

16. A combination according to claim 1 , wherein the apparatus is adapted to be retro-fitted to the diesel filter.

17. A vehicle comprising a combination according to claim 1 .

18. A combination according to claim 1 , wherein the outlet comprises a nozzle that fits over the drainage port.

19. A combination according to claim 1 , wherein the outlet aperture is oriented in a radial plane relative to the axis of rotation of the rotatable portion.

20. A combination according to claim 1 , wherein the manipulation portion is configured such that when the manipulation portion is manipulated by a user's hand, the manipulation portion moves together with the rotatable portion of the diesel filter.

21. A combination according to claim 1 , wherein the mounting apparatus comprises one of:
an interference fit between the apparatus and the rotatable portion of the diesel filter; or
a latching member configured to engage a side of the rotatable portion of the diesel filter.
