Patent number: 7832376Abstract: Damping elements for a fuel injection valve insertable into a receiving conduit of a cylinder head of an internal combustion engine are disposed between a valve housing of the fuel injection valve and a wall of the receiving conduit of the cylinder head. These damping elements, inter alia, decrease acoustic transfer from the fuel injection valve to the cylinder head. It is disadvantageous that conventional damping elements require a great deal of axial installation space with respect to a valve axis and have comparatively high manufacturing costs. With the damping element according to example embodiments of the present invention, the installation space required is reduced. Provision is made, according to example embodiments of the present invention, for the damping element to be in plate-shaped fashion.Type: GrantFiled: September 8, 2005Date of Patent: November 16, 2010Assignee: Robert Bosch GmbHInventors: Martin Mueller, Michael Huebel
