Abstract

An injector clip includes a lower plate formed to support a fuel injection portion of an injector, a base plate is formed to engage with and support a connection portion of the injector and an engagement support portion elastically supports the lower plate and the base plate to return the fuel injection portion to an original position after being displaced. A spring arm is formed by extending from the base plate to support a fuel inlet portion of the injector. Accordingly the load resulting from fuel injection of a fuel injector is attenuated and p a fuel injection device is prevented from rotating.

First claim

What is claimed is:

1. An injector clip comprising:
a lower plate that supports a fuel injection portion of an injector;
a base plate that contacts and supports a connection portion of the injector;
an engagement support portion that elastically supports the lower plate and the base plate to return a position of the fuel injection portion when the fuel injection portion is moved to its original position;
a spring arm formed by extending from the base plate to support a fuel inlet portion of the injector; and
a lower spring arm formed by extension of the lower plate and being bent in a direction toward the base plate to reinforce supporting force of the engagement support portion.

2. The injector clip according to claim 1 , wherein the lower plate a first end is coupled to the engagement support portion, having interior portion formed with a first seating aperture that seats the connection portion thereon and a second end that is opened to communicate with the first seating aperture.

3. The injector clip according to claim 2 , wherein the lower plate has the connection portion inserted into the first seating aperture and abuts with an end face of the fuel injection portion in the direction of the fuel inlet portion to elastically support the fuel injection portion.

4. The injector clip according to claim 1 , wherein the base plate is formed having a first end coupled to the engagement support portion, an interior portion having a second seating aperture to seat the connection portion thereon and a second end is formed to be opened to communicate with the second seating aperture.

5. The injector clip according to claim 4 , wherein the base plate receives the connection portion therein and is supported by the second seating aperture.

6. The injector clip according to claim 1 , wherein the engagement support portion is integrally formed with the lower plate and the base plate and formed by being bent twice having the lower plate and the base plate disposed with each other.

7. The injector clip according to claim 1 , wherein the spring arm has a first end coupled to the base plate and formed by being bent convexly with respect to the base plate and a second end that abuts the fuel inlet portion and formed having width of a face coupled to the base plate being greater than width of a face that abuts the fuel inlet portion.

8. The injector clip according to claim 1 , wherein the lower spring arm is configured to be bent in a direction from the second end of the lower plate toward the base plate having the lower spring arm that covers a bottom face of the base plate or abuts the bottom surface of the base plate.
