Abstract

A fluidic control element includes a housing having a fluid space formed between at least two housing parts. First and second flow channels may each have a sealing seat that opens into the fluid space. The fluidic control element may further include a two-armed lever which is configured to swivel in the fluid space. Each arm of the lever may be configured to open and close one of the flow channels in a corresponding end position. Additionally, a valve body may have a load-carrying core including a shaft mounted in the housing. The shaft may be rounded at least in the region in which it is embedded in a sealing ring that surrounds the lever arms.
