Fuel injector retention clip

A fuel injector clip for use in a fuel delivery system, comprising:

• a base having an inner peripheral surface at least a portion of which is configured for engagement with the body of a fuel injector when said clip is assembled with said fuel injector, said base defining a vertical axis extending through the center thereof;
• and
• a pair of arms extending from said base in an axially upward direction relative to said vertical axis, each of said arms including a finger, said fingers being configured for spring engagement with a pair of tabs disposed on a fuel outlet cup;
• said clip operative to limit the axial and torsional movement of said fuel injector when said clip is assembled with said fuel injector and said fuel injector is inserted in said cup.

A fuel delivery system comprising:

• a fuel rail having an outlet opening;
• an outlet cup, said cup including an inlet that is insertable into said outlet opening and a flange wherein said flange includes at least one slot therein, said cup defining a vertical axis extending through the center of said inlet of said cup;
• a fuel injector having a body with an inlet insertable within said cup;
• a clip having a base, said base including an inner peripheral surface, at least a portion of which is configured for engagement with said fuel injector body when said clip is assembled with said fuel injector, said clip further including at least one arm extending from said base in an axial upward direction relative to said vertical axis, said arm configured for insertion in said slot of said flange of said cup, said arm including an axially downward extending finger configured for engagement with said flange of said cup, said clip operative to limit the axial and torsional movement of said fuel injector when said fuel injector is assembled with said clip and inserted in said cup.

A fuel injector clip for use in a fuel delivery system, comprising:

• a base having an inner peripheral surface at least a portion of which is configured for engagement with the body of a fuel injector when said clip is assembled with said fuel injector, said base defining a vertical axis extending therethrough;
• and
• a pair of arms extending from said base in an axially upward direction relative to said vertical axis, each of said arms including a finger, said arms configured for insertion within a pair of corresponding slots disposed within a flange of a fuel outlet cup, and said fingers being configured for engagement with said flange;
• said clip operative to limit the axial and torsional movement of said fuel injector when said clip is assembled with said fuel injector and said fuel injector is inserted in said cup.

A fuel delivery system comprising:

• a fuel rail having an outlet opening;
• an outlet cup, said cup including an inlet that is insertable into said outlet opening and a rim, said cup further including at least first and second slots disposed in said rim of said cup, said cup defining a vertical axis extending through the center of said inlet thereof;
• a fuel injector having a body with an inlet insertable within said cup;
• a clip having a base, said base including open and a closed ends, said base further including an inner peripheral surface at least a portion of which is configured for engagement with said fuel injector body when said clip is assembled with said fuel injector, clip defining a vertical axis extending through the center thereof that is generally parallel to said axis of said cup;
• said clip further including at least one tab protruding from said closed end of said base in a radially outward direction relative to said vertical axis of said clip, and at least one ear extending from said open end of said base in an axial upward direction relative to said vertical axis of said clip, said at least one tab configured to be inserted within said first slot of said cup and said at least one ear configured to be inserted within said second slot of said cup and in engagement with said cup when the combination of said clip and said fuel injector is inserted into said cup,
• said clip operative to limit the axial and torsional movement of said fuel injector when said fuel injector is assembled with said clip and inserted in said cup.

A fuel injector clip for use in a fuel delivery system, comprising:

• a base having an open end, a closed end, and an inner peripheral surface at least a portion of which is configured for engagement with the body of a fuel injector when said clip is assembled with said fuel injector, said base defining a vertical axis extending therethrough;
• at least one protrusion protruding from said base in a radial direction relative to said vertical axis;
• and
• at least one tab spaced a predetermined distance apart from said at least one protrusion extending from said base in an axial upward direction relative to said vertical axis;
• said at least one protrusion configured to be inserted within a first slot in an injector cup of a fuel rail of said fuel delivery system and said at least one tab configured to be inserted within a second slot in said injector cup when the combination of said injector and said clip is inserted into said cup;
• said clip operative to limit the axial movement of said fuel injector when said clip is assembled with said fuel injector and said fuel injector is inserted in said cup, and to limit the torsional movement of said fuel injector when said clip is assembled with said fuel injector and said fuel injector is inserted in said cup by limiting radial expansion of said clip.
