Abstract

A pump comprises a pump body; an actuator; and, one or more active valves. The pump body at least partially defines a pumping chamber which has an inlet port and an outlet port. The actuator is situated at least partially in the pumping chamber for acting upon fluid in the pumping chamber. The active valve selectively opens and closes a port with which it is aligned. In some embodiments, the active valve comprises a piezoelectric element. In one implementation of the pump, both the inlet valve and the outlet valves are active valves. In another implementation of the pump, the inlet valve is an active valve but the outlet valve is a passive valve. In other embodiments, active valves operate in accordance with magnetic forces and have electric conductors or wiring embedded or otherwise formed therein in a coil shape to form a magnetic field.
