Abstract

A holder is used for fastening a fuel distributor to an internal combustion engine. The holder has a base element which is connected to the fuel distributor. A slotted sleeve is provided, which is connected to the base element, and the base element is braced on the internal combustion engine via the slotted sleeve. Furthermore, a system having the fuel distributor and a plurality of holders of this type is provided.

First claim

What is claimed is:

1. A holder for fastening a component to an internal combustion engine, comprising:
a base element configured to connect to the component; and
a slotted sleeve that is connected to the base element, wherein the base element is supported on the internal combustion engine at least via the slotted sleeve,
wherein:
the base element includes at least one first holder part, at least one further holder part, and a further sleeve;
the slotted sleeve is connected to the first holder part;
the first holder part is connected to the further holder part via the further sleeve;
a through hole extends along a fastening axis through the further holder part, the further sleeve, the first holder part, and the slotted sleeve;
a fastening element is configured to be guided through the through hole along the fastening axis in order to connect the base element indirectly to the internal combustion engine;
the slotted sleeve has a connection surface that is spot connected to the first holder part;
the slotted sleeve has an annular contact face that is interrupted by at least one slot that is opposite to the connection surface; and
the slotted sleeve is configured to rest on a surface of the internal combustion engine via the slot when the base element is indirectly connected to the internal combustion engine,
wherein the at least one slot extends parallel to the fastening axis of the slotted sleeve from the contact face of the slotted sleeve to a surface of the slotted sleeve that is opposite to the connection surface of the slotted sleeve.

2. The holder as recited in claim 1 , wherein the component includes a fuel rail.

3. The holder as recited in claim 1 , wherein the slotted sleeve rests against the surface of the internal combustion engine via the annular contact face when the base element is indirectly connected to the internal combustion engine.

4. The holder as recited in claim 1 , wherein:
the base element is developed in such a way that an orientation of a longitudinal axis of the component is predefined when connecting the base element to the component, and
a slot of the slotted sleeve faces the longitudinal axis or faces away from the longitudinal axis.

5. A system, comprising:
a component; and
a plurality of holders that fasten the component to an internal combustion engine, wherein at least one of the holders includes:
a base element configured to connect to the component, and
a slotted sleeve that is at least indirectly connected to the base element, wherein the base element is braced on the internal combustion engine at least via the slotted sleeve,
wherein:
the base element includes at least one first holder part, at least one further holder part, and a further sleeve;
the slotted sleeve is connected to the first holder part;
the first holder part is connected to the further holder part via the further sleeve:
a through hole extends along a fastening axis through the further holder part, the further sleeve, the first holder part, and the slotted sleeve;
a fastening element is configured to be guided through the through hole along the fastening axis in order to connect the base element indirectly to the internal combustion engine;
the slotted sleeve has a connection surface that is spot connected to the first holder part;
the slotted sleeve has an annular contact face that is interrupted by at least one slot that is opposite to the connection surface; and
wherein the at least one slot extends parallel to the fastening axis of the slotted sleeve from the contact face of the slotted sleeve to a surface of the slotted sleeve that is opposite to the connection surface of the slotted sleeve,
wherein the contact face of the slotted sleeve is configured to:
rest against a surface of the internal combustion engine in a planar manner; and
frictionally engage the surface of the internal combustion engine,

wherein the slotted sleeve is connected to the base element via multiple welding spot connections.

6. The system as recited in claim 5 , wherein:
the component has a tubular body, and
a slot of the slotted sleeve faces a longitudinal axis of the tubular body or faces away from the longitudinal axis of the tubular body.
