ディスク状キャビティを備えるポンプ
Document Type and Number:
Japanese Patent JP2012528981
Kind Code:
A
Abstract:
A pump having a substantially cylindrical shape and defining a cavity formed by a side wall closed at both ends by end walls wherein the cavity contains a fluid is disclosed. The pump further comprises an actuator operatively associated with at least one of the end walls to cause an oscillatory motion of the driven end wall to generate displacement oscillations of the driven end wall within the cavity. The pump further comprises an isolator operatively associated with a peripheral portion of the driven end wall to reduce dampening of the displacement oscillations. The pump further comprises a valve for controlling the flow of fluid through the valve. The valve has first and second plates with offsetting apertures and a sidewall disposed between the plates around the perimeter of the plates to form a cavity in fluid communication with the apertures. The valve further comprises a flap disposed and moveable between the first and second plates and having apertures substantially offset from the apertures of one plate and substantially aligned with the apertures of the other plate. The flap is motivated between the two plates in response to a change in direction of the differential pressure of fluid across the valve.
