ブの発振防止装置。 The housing includes a spool slidably fitted into the housing, a supply passage formed in the housing, and a communication passage opened on the outer periphery of the spool, and the communication passage is connected to the housing by moving the spool forward and backward. In a spool valve that communicates with or is separated from a supply passage to control the communication state therebetween, a small diameter portion is provided on the outer periphery of the spool from the communication passage to the supply passage side to form a small gap with the housing. An oscillation prevention device for a spool valve, characterized in that an annular groove for oscillation prevention is formed in the small diameter portion.
