Abstract

An injector clamp for clamping at least two injectors to an engine head includes a body having at least a first arm and a second arm. Each arm having a first clamping surface and a second clamping surface on opposing sides of the body. A distance between the first clamping surfaces of the first arm and the second arm is different from a distance between the second clamping surfaces of the first arm and the second arm. The body is configurable, for use, in one of: a first position in which the first clamping surfaces from each of the first and second arms can abut with an injector; and a second position in which the second clamping surfaces from each of the first and second arms can abut with an injector.

First claim

What is claimed is:

1. An injector clamp for clamping at least two injectors to an engine head, the injector clamp comprising:
a body having at least a first arm and a second arm, each arm having a first clamping surface and a second clamping surface on opposing sides of the body, wherein a distance between the first clamping surfaces of the first arm and the second arm is different from a distance between the second clamping surfaces of the first arm and the second arm, wherein the body is configurable, for use, in one of:
a first position, wherein the first clamping surfaces from each of the first and second arms abut an injector; and
a second position, wherein the second clamping surfaces from each of the first and second arms abut an injector.

2. The injector clamp assembly of claim 1 , wherein the body further comprises:
a first bolting area disposed between the second clamping surfaces of the first arm and the second arm; and
a second bolting area disposed between the first clamping surfaces of the first arm and the second arm.

3. The injector clamp assembly of claim 2 , wherein a height of the body measured between the first bolting area and the pair of second clamping surfaces is different from a height of the body measured between the second bolting area and the pair of first clamping surfaces.

4. The injector clamp assembly of claim 3 , wherein the body defines a central orifice therein, the central orifice being co-located with and configured to extend through the first and second bolting areas.

5. The injector clamp assembly of claim 4 further comprising:
an elongated stud slidably received through the central orifice, the stud having a first threaded portion and a second threaded portion, wherein the first threaded portion is configured to releasably engage with a threaded receptacle defined on the engine head; and
a fastening element disposed above the body, the fastening element threadably engaged with the second threaded portion of the elongated stud and configured to abut with at least one of: the first bolting area and the second bolting area on the body.

6. The injector clamp assembly of claim 5 further comprising a retaining member disposed between the fastening element and the body, the retaining member configured to maintain a position of the fastening element stationary with respect to the body.

7. The injector clamp assembly of claim 1 further comprising at least a pair of indelible markings formed on the opposing sides of the body.

8. The injector clamp assembly of claim 7 , wherein each of the indelible markings is visually indicative of one of:
the first position of the body, wherein the body is configured to facilitate mounting of fuel injectors to an engine head having a first configuration; and
the second position of the body, wherein the body is configured to facilitate mounting of fuel injectors to an engine head having a second configuration.

9. An injector clamp for clamping at least two injectors to an engine head, the injector clamp comprising:
a body having at least a first arm and a second arm, each arm having a first clamping surface and a second clamping surface on opposing sides of the body;
a first bolting area disposed between the second clamping surfaces of the first arm and the second arm; and
a second bolting area disposed between the first clamping surfaces of the first arm and the second arm, wherein a height of the body measured between the first bolting area and the pair of second clamping surfaces is different from a height of the body measured between the second bolting area and the pair of first clamping surfaces.

10. The injector clamp assembly of claim 9 , wherein a distance between the first clamping surfaces of the first arm and the second arm is different from a distance between the second clamping surfaces of the first arm and the second arm.

11. The injector clamp assembly of claim 9 , wherein the body is configurable, for use, in one of:
a first position, wherein the first clamping surfaces from each of the first and second arms abut an injector; and
a second position, wherein the second clamping surfaces from each of the first and second arms abut an injector.

12. The injector clamp assembly of claim 9 , wherein the body defines a central orifice therein, the central orifice being co-located with and configured to extend through the first and second bolting areas.

13. The injector clamp assembly of claim 12 further comprising:
an elongated stud slidably received through the central orifice, the stud having a first threaded portion and a second threaded portion, wherein the first threaded portion is configured to releasably engage with a threaded receptacle defined on the engine head; and
a fastening element disposed above the body, the fastening element threadably engaged with the second threaded portion of the elongated stud and configured to abut with at least one of: the first bolting area and the second bolting area on the body.

14. The injector clamp assembly of claim 13 further comprising a retaining member disposed between the fastening element and the body, the retaining member configured to maintain a position of the fastening element stationary with respect to the body.

15. The injector clamp assembly of claim 9 further comprising at least a pair of indelible markings formed on the opposing sides of the body.

16. The injector clamp assembly of claim 15 , wherein each of the indelible markings is visually indicative of one of:
the first position of the body, wherein the body is configured to facilitate mounting of fuel injectors to an engine head having a first configuration; and
the second position of the body, wherein the body is configured to facilitate mounting of fuel injectors to an engine head having a second configuration.

17. A reversible injector clamp assembly for mounting at least a pair of injectors on one of two different configurations of engine heads, the reversible injector clamp assembly comprising:
a body extending along a longitudinal axis and having a pair of arms, wherein each arm carries a pair of appendages laterally spaced apart in relation to one another, each of the appendages having a lower portion and an upper portion respectively, wherein a pair of first clamping surfaces defined in the lower portions of the appendages from the pair of arms is spaced apart from one another at a first distance, and wherein a pair of second clamping surfaces defined in the upper portions of the appendages from the pair of arms is spaced apart from one another at a second distance lesser than the first distance.

18. The reversible twin injector clamp assembly of claim 17 , wherein the body defines a central orifice extending therethrough and disposed along a vertical axis, the vertical axis being disposed substantially perpendicular to the longitudinal axis.

19. The reversible twin injector clamp assembly of claim 18 further comprising:
an elongated stud slidably received through the central orifice, the stud having a first threaded portion and a second threaded portion, wherein the first threaded portion is configured to releasably engage with a threaded receptacle defined on the engine head; and
a fastening element threadably engaged with the second threaded portion of the elongated stud and configured to abut with the body.

20. The reversible twin injector clamp assembly of claim 17 further comprising at least a pair of indelible markings formed on the body, wherein each of the indelible markings is visu
