Abstract

PURPOSE:To prevent creation of noise by disposing a check valve in a cap-like valve cover which is fit at the open end of a central passage of a movable magnet core. CONSTITUTION:A cylindrical seat body 14' is fit at the open end of the central passage of a movable magnet core 8. A cap-like valve cover 35 in which many fluid through-holes 35a are made is provided in such a manner as to cover the seat member 14'. A rubber ball 16' which is forced to be seated by a spring 15' is disposed inside the valve cover 35. A short stroke of the movable magnet core 8 and a slow cycle of its shifting may be enough for ensuring a large amount of discharged fluid, thereby silencing a noise produced during operation.
