A valve comprises: a first plate (116) having apertures (120) extending through said first plate; a second plate (114) having apertures (118) extending through said second plate, the apertures (118) being substantially offset from the apertures (120) of said first plate; a spacer (112) disposed between said first plate and said second plate to form a cavity (115) therebetween; and, a flap (117) disposed and moveable between said first and second plates, said flap having apertures (122) substantially offset from the apertures (120) of said first plate and substantially aligned with the apertures (118) of said second plate. A pump (10) containing said valve is also disclosed. The pump has a sylindrical shape and defines a cavity (10) formed by a side wall (19) closed at both ends by end walls (12, 13), wherein an actuator (20) causes an oscillatory motion on one end wall to generate displacement oscillations. Methods for fabricating the valve and for mounting the valve in the pump. |
