Japanese Patent JP2022069222
Kind Code:
A
Abstract:
To provide an electromagnetic pump capable of reducing a discharge amount per one time by countermeasures excluding miniaturization of an orifice.SOLUTION: An electromagnetic pump 10 guides a fluid sucked to a pump chamber 62 from a suction port 12 by reciprocating a plunger 60, to a buffer chamber 110 formed between the plunger 60 and a discharge port 12. The electromagnetic pump 10 presses out the fluid stored in the buffer chamber 110 to discharge the same toward a discharge port 14 by reciprocating the plunger 60. A plurality of orifices 100, 102, 104 are formed in series on a flow passage from the buffer chamber 110 to the external at a discharge side 116.SELECTED DRAWING: Figure 3
