Abstract

PURPOSE: To provide an operation chamber for the outside of diaphragm and provide an additional sealed operation chamber with yoke internal face and side plate and moving element end face for increasing discharge rate by operating these plural operation chambers with the same driving unit.
CONSTITUTION: An operation chamber 8 is provided for the outside of diaphragm 7. An operation chamber 23 is provided for the clearance between yoke 1 internal side plate 5 and moving element 3a end face, where both chambers are communicated through the passage 24. With a coil 2 energized, the moving element 3a acts reciprocating motion in an axial direction. With the moving element 3a moved, the operation chamber 23 enclosed in yoke 1 is also boosting pressure of liquid by operating jointly with the operation chamber 8. Accordingly, this enables to increase discharge rate by operating a plural operation chambers 8, 23 in the same driving unit.
