Title: FLAT GASKET
Abstract:
The present invention relates to a flat gasket (1) as is used for example as a transmission control plate, as a cylinder head gasket, as a gasket for an oil cooler or some other engine gasket or the like. The present invention thus also relates to transmission control plates, cylinder head gaskets and gaskets for oil coolers, which are configured as the flat gasket (1) according to the invention. The flat gasket (1) according to the invention has a carrier layer (10) and at least one first sealing layer (20, 20'), at least one through-opening (2) for a fluid, said through-opening (2) passing through the flat gasket (1) and all the layers thereof, and at least one spring element (26, 26', 26") with a spring plate (25, 25') and a retaining region (23) for the spring plate (25, 25'), said retaining region (23) being connected to the spring plate and at least regionally surrounding the latter. It is characterized in that the spring element (26, 26', 26") is part of the first sealing layer (20, 20'), or the spring element (26, 26', 26") is arranged, in projection onto the plane of the carrier layer (10), at least regionally or completely in the through-opening (2) through the flat gasket (10), in particular in the throughflow opening (12) through the carrier layer (10), and is connected to the first sealing layer (20) at least regionally in a form-fitting and/or cohesive manner.
