Abstract
For a low-pressure injection valve, a piezoceramic valve plate as a flexural resonator, the valve plate having a carrier plate and on one side or on both sides silvered piezoceramic plates held by a binding layer. It is the object of the present invention to provide a flexural resonator which comprises within a large temperature range a proper and reliable connection between the carrier plate and the ceramic plate. The carrier plate consists of a metallic glass, and the binding layer is a soft solder with Zn as main component and an alloy suppressor such as Pb, Cd, and/or Ag.
