Document Type and Number:
Japanese Patent JP2000505521
Kind Code:
A
Abstract:
A vibrating membrane fluid circulator comprising an internal hydraulic circuit made up in succession of an admission orifice (1), a pump body (2), and a delivery orifice (3), the pump body (2) defining, in operation, a space (4, 18, 30) having rigid walls (5, 6) between which a deformable membrane (9) is placed having means for coupling its end (11) adjacent to the admission orifice to a motor member (39) generating a periodic excitation force substantially normally to the surface thereof, said membrane (9) being associated with means for creating tension parallel to the fluid circulation direction, said membrane constituting the medium for waves travelling from the end subjected to the excitation force towards its opposite end situated adjacent to the delivery orifice, said displacement being accompanied by forced damping due to the shape of the rigid walls so as to transfer energy from the membrane to the fluid giving rise to a pressure gradient and to fluid flow related to the dimensions of the pump body and of the membrane, the shape and the spacing of the rigid walls, the mechanical characteristics of the membrane, and the characteristics of its excitation and its tension state.
