Title:
ELECTROMAGNETIC OSCILLATING DIAPHRAGM PUMP
Document Type and Number:
WIPO Patent Application WO/2012/141126
Kind Code:
A1
Abstract:
Provided is an electromagnetic oscillating diaphragm pump capable of increasing pump efficiency by increasing the width of oscillation of a diaphragm regardless of whether the pressure inside a compression chamber increases. Diaphragms (2) are fixed to both end parts of an oscillator (1), which has magnets (11a, 11b). AC-powered electromagnets are provided facing the magnets (11a, 11b) of the oscillator (1). The electromagnet side of each diaphragm (2) is covered by a frame (4) fixedly attached to the outer circumference of the diaphragms (2), and the opposite side of each diaphragm (2) is covered by a pump casing (5). The pump casing (5) includes a compression chamber (51) in contact with the diaphragm (2), an intake chamber coupled to the compression chamber (51) via an intake valve, and a discharge chamber (53) connected to the compression chamber (51) via a discharge valve (53a). The intake chamber or the discharge chamber (53) is connected to the frame (4) via a communication hole (6).
