Abstract
A micro-pump is disclosed for pneumatically causing a bulging/retracting motion of a plurality of micro-diaphragms disposed in an array along a channel through which a fluid is being driven. The pump includes channel means (10) including a first port (11), a second port (12) and a flow-through space (13) providing a communication therebetween; a plurality of diaphragms (21a-21e) disposed in an array along the flow-through space (13); diaphragm support means (20) including a plurality of actuating gas spaces (22a-22e) which opposes the rear surfaces of the respective diaphragms; a plurality of reciprocatory motion means for individually imparting an oscillation of pneumatic pressure to the respective actuating gas spaces (22a-22e), and drive means for driving the reciprocatory motion means for driving motion with phase differences therebetween so that the upper dead center shifts in the direction of the array.
