御弁。 A valve body with a slide hole formed therein and a pressure oil inlet and a pressure oil outlet opened in the slide hole, a spool slidably inserted into the slide hole, and axial displacement of the spool due to magnetic force within the slide hole. The spool has a first slit in the axial direction having a lateral width consisting of at least a small width part and a wide part, and an axial line having a lateral width of the wide part obtained by removing the small width part from the first slit. second direction
A slit is formed, and the slit is
It is interposed in the communication path between the pressure oil inlet and the pressure oil outlet, and depending on the axial displacement position of the spool, the degree of opening from zero to fully open is given to the communication between the pressure oil inlet and the pressure oil outlet. , at the start of opening,
An electromagnetic control valve characterized in that the spool is formed in a position direction such that it opens only from a minute width portion.
