Fuel injector clamp
View Patent ↗A fuel injector clamp and method of clamping a fuel injector includes clamp members each including a central body with a concaved section and two horizontally offset passageways. Clamp members are oppositely oriented such that the concaved section forms a region adapted to engage a fuel injector. Offset passageways are aligned such that a top passageway of one member is aligned with a bottom passageway of the opposing member. A fastening mechanism is passed through a first pair of aligned passageways to form a hinge, allowing clamp members to pivot about the hinge so a fuel injector can be disposed between the concaved sections. Members are then pivoted towards each other to close the clamp assembly; a second fastening mechanism is passed through a second pair of aligned offset passageways to lock the injector into place.
1. A clamping device for holding a fuel injector to a cylinder head of an internal combustion engine, comprising:
a clamp assembly having a first clamp member and a second clamp member, the first and second clamp members adapted to be pivotally connected together at base ends thereof by a first connection, and removably connected at distal ends thereof by second connection, the clamp members being configured to have a space there between that is adapted to capture a fuel injector when the base ends and distal ends are respectively connected together, the clamp assembly being fastenable to the cylinder head and the distal ends being separable by disconnecting the second connection in order to remove a fuel injector from the cylinder head.
2. The clamping device according to claim 1 , wherein the first and second clamp members are identically configured.
3. The clamping device according to claim 1 , wherein the first connection connects the base ends of the first and second clamp members to the cylinder head, and the second connection connects the distal ends of the first and second clamp members to the cylinder head.
4. The clamping device according to claim 1 , wherein the first and second clamp members each have a concave curvature between respective base and distal ends.
5. The clamping device according to claim 1 , wherein when the first and second clamp members are respectively connected at base and distal ends, the base ends of the first and second clamp members overlap and the distal ends of the first and second clamp members overlap.
6. The clamping device according to claim 1 , wherein the first connection comprises a first fastener that connects the base ends of the first and second clamp members to the cylinder head, and the second connection comprises a second fastener that connects the distal ends of the first and second clamp members to the cylinder head, wherein the base ends have a degree of movement along the first fastener when the first fastener is fully threaded into the cylinder head, wherein the first and second clamp members press the fuel injector along a pivot axis toward the cylinder head when the second fastener is threaded into the cylinder head and tightened to a preselected torque.
7. A method of clamping a fuel injector on to a cylinder head comprising the steps of:
oppositely engaging a pair of clamp members by aligning one clamp member at 180 degrees from the other such that flat sides of each clamp member face upwards, and concaved sections from each clamp member face each other to form a region adapted to engage a fuel injector;
aligning a first set of offset passageways on one end of the oppositely engaged clamp members to form a first set of aligned offset passageways;
passing a first fastening mechanism through the first set of aligned offset passageways;
disposing a fuel injector between the oppositely engaged clamp members;
aligning a second set of offset passageways on the other end of the oppositely engaged clamp members to form a second set of aligned offset passageways;
passing a second fastening mechanism through the second set of aligned offset passageways;
tightening the first fastening mechanism into the cylinder head; and
tightening the second fastening mechanism into the cylinder head.
8. The method of claim 7 , wherein the step of aligning a first set of offset passageways further comprises the step of lining up a top offset passageway of one clamp member with a bottom offset passageway on the opposing member.
9. The method of claim 7 , wherein the step of passing a first fastening mechanism through the first set of aligned offset passageways effectively creates a hinge about which each clamp member can pivot.
10. The method of claim 9 , wherein the step of disposing a fuel injector between the clamp members further comprises the step of pivoting the clamp members away from each other about the hinge such that enough space is created between the concaved sections of each clamp member for a fuel injector to be disposed between the concaved sections.
11. The method of claim 7 , wherein the step of aligning a second set of offset passageways on the other end of the oppositely engaged clamp members to form a second set of aligned offset passageways further comprises the step of pivoting the clamp members towards each other.
12. The method of claim 7 , wherein the step of tightening the first fastening mechanism further comprises the step of tightening the first fastening mechanism in a threaded bore until the first fastening mechanism makes contact with a boss on the cylinder head.
13. The method of claim 7 , wherein the step of tightening the second fastening mechanism further comprises the step of tightening the second fastening mechanism in a threaded bore until a desired torque load is reached.
