A two-cavity pump (10) has a side wall (22) closed by two end walls (12,19) for containing a fluid. An actuator (40) is disposed between the two end walls (12,19) and functions as a portion of a common end wall (21) of the two cavities (16,23). The actuator (40) causes an oscillatory motion of the common end wall (21) to generate radial pressure oscillations of the fluid within both cavities (16,23). An isolator (30) flexibly supports the actuator (40). The first cavity (16) includes the single valve (35) disposed in one of a first and second apertures (25,27) in the end wall (12) to enable fluid flow in one direction. The second cavity (23) includes the bidirectional valve (36) disposed in one of a third and fourth apertures (26,28) in the end wall (19) to enable fluid flow in both directions. |
