ELECTROMAGNETIC PILOT OPENING/CLOSING VALVE

摘要

An electromagnetic pilot opening/closing valve includes: a valve main body member that includes a sliding hole; a main valve body that is slidably provided in the sliding hole; a movable iron core; and a fixed iron core. The main valve body includes a second sliding hole. A pilot valve body is provided in the second sliding hole. The movable iron core and the pilot valve body are designed to slidably engage with each other, and the movable iron core and the main valve body are designed to slidably engage with each other with a play therebetween. When the movable iron core is attracted by the fixed iron core by energization of the coil, the movable iron core causes the pilot valve body to slide inside the second sliding hole and sliding of the pilot valve body causes the main valve body to slide inside the sliding hole.
