Abstract
A valve comprises an orifice plate () having one or more orifices () through which a fluid may flow, and one or more piezo-electric elements (). Each element () has a face positioned to contact the orifice plate at an orifice. Each element has a first state in which it abuts the plate to prevent flow of fluid through the associated orifice and a second state in which the face is spaced from the plate to allow flow through the associated orifice. A controller () selectively applies a first voltage to an elements to cause it to adopt the first state and applies a second voltage to the one or more elements to cause the elements to adopt the second state.
