Abstract
A fluid dispensing subassembly has a diaphragm arranged to be operated on by a transducer, a body pressure chamber arranged to be operated on by the diaphragm, and an adhesive attachment layer arranged between the diaphragm and the body pressure chamber. A fluid dispensing subassembly has a body pressure chamber formed of either a single plate or set of plates, a diaphragm arranged to operate on the body pressure chamber, and an adhesive layer arranged between the body pressure chamber and the diaphragm. A method of manufacturing a fluid dispensing subassembly includes forming a body pressure chamber from a body plate or a set of plates including a body plate, and adhesively bonding a diaphragm plate to at least the body plate of the fluid dispensing subassembly.
