Abstract
A dispensing system includes a piezoelectric stack having a distal end and being configured to expand upon application of a voltage such that the distal end is moved by a first length. The system further includes an amplifier with a primary surface to contact the distal end of the stack and a secondary surface, a base configured to contact the secondary surface, and a valve assembly with an outlet orifice and valve element. The valve element is configured to move in first and second directions and is coupled with the amplifier. When the distal end is moved by a first length, a portion of the amplifier is moved by a second length that is greater than the first length, and the valve element is moved in a first direction by the second length.
