Abstract
A device for holding down a valve for metering fuel in the cylinder head of an internal combustion engine is provided. The valve is inserted for fuel supply, using a connection piece, into a sealing region which presses against the connection piece at an outlet opening of a manifold fixed to the cylinder head. Between a first support shoulder on the side of the valve and a second support shoulder on the side of the manifold, the device has a clamped spring element for transferring a holding-down force onto the valve. In order to achieve an inward deflection of the spring element required for the transfer of the holding-down force, the spring element is prestressed to a prestressing force that is reduced with respect to the holding-down force, and the prestressed spring element is fixed on the valve.
