## Abstract

Various embodiments include a holding component for securing a fuel injector to an injector cup comprising: a U-shaped holding element with two parallel supporting arms for engaging opposite sides of an annular groove in the fuel injector to secure the fuel injector in the injector cup; a base part; two resilient arms extending from the base part for engaging the outer surface of the injector cup; and a depending leg engageable in a corresponding receiving part on the fuel injector to accurately position the fuel injector angularly relative to the injector cup.

## Claims

### Claim 1

A holding component for securing a fuel injector to an injector cup, the holding component comprising:
a U-shaped holding element with two parallel supporting arms for engaging opposite sides of an annular groove in the fuel injector to secure the fuel injector in the injector cup;
a base part;
two resilient arms extending from the base part for engaging an outer surface of the injector cup; and
a depending leg engageable in a corresponding receiving part on the fuel injector to accurately position the fuel injector angularly relative to the injector cup.

### Claim 2 (depends on 1)

A holding component according to claim 1, wherein the holding component comprises a molded plastics material.

### Claim 3 (depends on 1)

A holding component according to claim 1, wherein the holding element comprises a one-piece component formed from a sheet metal material.

### Claim 4 (depends on 1)

A holding component according to claim 1, wherein the two parallel supporting arms comprise a double thickness of material and the two resilient arms comprise a single thickness of material.

### Claim 5 (depends on 1)

A holding component according to claim 1, further comprising a second depending leg, wherein the two depending legs are in spaced parallel relationship, each leg engageable in a corresponding receiving part on the fuel injector.

### Claim 6 (depends on 1)

A holding component according to claim 1, wherein roots of the resilient arms extend from a resilient web of the base part enabling the resilient arms to move in a direction of their longitudinal extent.

### Claim 7 (depends on 1)

A holding component according to claim 1, wherein at respective free ends, the two resilient arms have inwardly extending projections which, when the holding component is inserted in the injector cup, engage the injector cup to lock the holding component in position.

### Claim 8

A fuel injection assembly having a longitudinal axis, the fuel injection assembly comprising:
an elongate fuel injector having a fuel inlet port, a fuel outlet port, and an annular groove;
an injector cup with a generally cylindrical body extending along the longitudinal axis with an upper end and a lower end and having an outer surface;
a holding component comprising:
a U-shaped holding element with two parallel supporting arms for engaging opposite sides of the annular groove to secure the fuel injector in the injector cup;
a base part;
two resilient arms extending from the base part for engaging the outer surface of the injector cup; and
a depending leg engageable in a corresponding receiving part on the fuel injector to accurately position the fuel injector angularly relative to the injector cup;
wherein
the injector cup has a recess at the lower end receiving the fuel inlet port;
an opening formed in a peripheral wall of the injector cup receiving the holding element;
wherein the supporting arms engage opposite sides of the annular groove.

### Claim 9 (depends on 8)

A fuel injector assembly according to claim 8, wherein the holding component further comprises a second depending leg and the two depending legs are in spaced parallel relationship, each leg engaged in a corresponding receiving part on the fuel injector.

### Claim 10 (depends on 9)

A fuel injector assembly according to claim 9, wherein the receiving parts comprise recesses in the fuel injector.

### Claim 11 (depends on 8)

A fuel injector assembly according to claim 8, wherein at respective free ends, the two resilient arms have inwardly extending projections engaging the injector cup to lock the holding component in position.

### Claim 12 (depends on 11)

A fuel injector assembly according to claim 11, wherein the recesses are formed in a plastics component part of the fuel injector.
