Abstract
A fastening device for fastening a fuel injection valve in a bore in the cylinder head of an internal combustion engine, in which the fuel injection valve has a longitudinal axis. A clamping jaw is acted upon by a fastening force, and the clamping jaw rests with at least one support face on a support point of the fuel injection valve, so that the clamping jaw is pressed with its support face against the support point. The support point on the fuel injection valve (5) is embodied linearly, and the line is straight and in its imaginary extension intersects and is perpendicular to the longitudinal axis of the fuel injection valve.
Claims7
A clamping device for fastening a fuel injection valve (5), having a longitudinal axis (6), in a bore (3) in the cylinder head of an internal combustion engine, the clamping device comprising,
- a clamping jaw (20) having at least one support face (30),
- a linear support point (32) on the injection valve, the linear support point (32) being defined by chamfers (37) intersecting to form a linear ridge extending in a straight line perpendicular to and lying in a plane containing the longitudinal axis (6) of the injection valve (5), and
- means applying a fastening force pressing the support face (30) of the clamping jaw (20) against the linear support point (32).
A clamping device for fastening a fuel injection valve (5), having a longitudinal axis (6), in a bore (3) in the cylinder head of an internal combustion engine, the clamping device comprising,
- a clamping jaw (20) having at least one support face (30),
- a linear support point (32) on the injection valve, the linear support line (32) being defined by a jacket line of a support cylinder (42) supported on the injection valve (5) and having a longitudinal axis (44) intersecting and lying in the same plane as the longitudinal axis (6) of the injection valve (5), and
- means applying a fastening force pressing the support face (30) of the clamping jaw (20) against the support cylinder (42).
