Abstract

PURPOSE: To manufacture a spool valve easily and improve sealing faculty by forming a spool and a spool chamber to have an equal diameter over the total length and allowing coolant to circulate in the hollow ring which is fitted on the surface of the spool.
CONSTITUTION: The spool chamber and a spool 12 which are arranged in a valve body 11 are formed to have a circular section having equal diameter over the whole length, and on the surface of the interface part of the port closure parts 12a and 12b of the spool 12 and the port communication part 12d, hollow rings 13 and 14 are arranged, and coolant passages 15a, 15b and 16a, 16b are allowed to communicate to the hollow rings 13 and 14. Therefore, the molten resin which arrives at the surface of the hollow rings 13 and 14 is cooled and solidified, and due to this synthetic resin cooled and solidified, the surroundings of the rings 13 and 14 is sealed, so sealing faculty is improved, and as the spool and spool chamber have equal diameter, manufacture can be facilitated.
