Abstract
A pump comprising a housing and a flexible diaphragm mounted in the housing. A first region of the diaphragm partially defines a first pumping chamber, and the pumping chamber has an inlet and an outlet. A wobble plate drive is coupled to the first region of the diaphragm to provide a pumping action in the pumping chamber. The wobble plate drive has a nutating axis, and the first region of the diaphragm lies radially outwardly of the nutating axis. The first region of the diaphragm has a generally annular ramp section which flexes when driven by the wobble plate drive to provide the pumping action, and the ramp section is wider radially at a location remote from the nutating axis than at a location nearer the nutating axis. The pump also has a single outlet valve arranged to serve multiple pumping chambers.
