Abstract

Flat gasket with a gasket plate comprising at least one sheet metal layer, in which fluid passage openings, screw holes adjacent to these and elastically deformable sealing elements enclosing the fluid passage openings are formed. On the one hand, to impede as little as possible sliding movements of the components to be arranged on either side of the flat gasket relative to one another and to the flat gasket, and, on the other hand, to create a fixed point for the assembled flat gasket, the flat gasket is designed such that the gasket plate has for at least a first one of its fluid passage openings in the area of a screw hole adjacent to this opening a spring element which is capable of elastic deformation perpendicularly to the gasket plate, and that the gasket plate has for at least a second one of its fluid passage openings adjacent thereto a screw hole which is without a spring element.
