Title:
音響共振流体ポンプ
Document Type and Number:
Japanese Patent JP6725419
Kind Code:
B2
Abstract:
A fluid pump includes a pump body having upper and lower parts, each comprising a substantially cylindrical side wall closed at one end by a substantially circular end wall and partially closed at the opposite end by an actuator disposed in a plane substantially parallel to and between the end walls. A single cavity is thereby formed having upper and lower portions. The cavity encloses the actuator and is bounded by the end walls and side walls of the pump body and the surfaces of the actuator. A substantially open actuator support structure connects the actuator to the pump body and enables free flow of fluid between the upper and lower cavity portions. At least two apertures are provided through the pump body walls, at least one of which is a valved aperture. All of the apertures located substantially at the centres of the end walls are valved apertures. In use, the actuator oscillates in a direction substantially perpendicular to the plane of the end walls causing an acoustic wrapped standing wave to exist in the cavity and thereby causing fluid flow through said apertures.
