Sealing arrangement, especially for injectors of an internal combustion engine and method for manufacturing such a sealing seat |
摘要 |
<p>The seat surface for the valve ball (1) in the conical valve seat (3) has an annular circular arc shaped longitudinal section and is worked into the conical surface by fine finishing work. The radius of the circular arc forming the seat surface is larger than the radius of the valve ball. The trough-shaped indentation of the seat surface is measured, so that, measured in cross-section, any deviations in the shape of the conically finished valve seat from the circular form are eliminated at least in the apex area of the arc seat surface. An Independent claim describes a method for producing a sealing seat by using a cylindrical grinding block to finish the seat, in which the tool holder and workpiece holder rotate in opposite directions.</p> |
