Abstract
A fluid device including a fluid chamber which is designed for receiving a fluid and which is commonly delimited by a device housing and a bending-elastic membrane element. The membrane element with a peripheral edge section is fixed to the device housing in a fluid-tight manner and has a membrane working section which is framed by the peripheral edge section and which for the change of the volume of the fluid chamber can be elastically deflected by a piezoactuator. The membrane element consists of a rubber-elastic material, wherein the piezoactuator comprises a drive section which extends along the membrane working section, is embedded into the membrane element and is enveloped by the rubber-elastic material of the membrane element.
