Claim Text:
1. A device for holding down a valve for metering fuel in a cylinder head bore provided in a cylinder head of an internal combustion engine, the valve being inserted, by a connection piece, into a sealing region which presses against the connection piece on an outlet opening of a manifold which is able to be fixed on a cylinder head for supplying fuel, the device comprising: a spring element clamped in between a first support shoulder on the valve side and a second support shoulder on the manifold side, the spring element transferring a holding-down force to the valve; wherein the spring element is prestressed to a prestressing force which is reduced compared to the holding-down force, and the prestressed spring element is fixed on the valve using a securing member situated on the valve, wherein the spring element generates no spring force between the two support shoulders when the connection piece is pushed into the sealing region, and wherein the spring element is a helical compression spring.
