Abstract

PURPOSE: By constituting or pump that inhales and exhales fluid via a work-chamber by driving a plunger directly by means of an electromagnetic reciprocal drive device with a permanent magnet as the movable piece, to make the whole apparatus smaller and to obtain a higher efficiency.
CONSTITUTION: If electro-magnetic coil 6 inserted into yoke 4 is connected to an alternative current power source, movable piece 7 which is formed by attaching magnetic pole end 9 to the both ends of permanent magnet 8 reciprocates by way of axial alternating fields, driving plunger 13 on. Consequently the fluid inhaled from inhalation port 22 into inhalation chamber 20 by the capacity fluctuations of work-chamber 24, is exhaled from exhalation port 23 via inhalation valve 16, exhalation valve 17 and exhalation chamber 21. In this case, since the capacity of space 25 formed by the ends of side-plate 11 and the posterior of plunger 13 varies by the reciprocal motion of plunger 13, a pressure fluctuation generates. So, if breather 15 is installed to support member 12, it is possible to drive plunger 13 smoothly and efficiently.
