Abstract
A solenoid valve has a tapered valve seat disposed between a first flow passage and a second flow passage, a reduced diameter side of the valve seat that is connected with the first flow passage, and a valve body having a closing portion that reduces its diameter toward a tip facing the valve seat. The first flow passage and the second flow passage are connected/disconnected by sliding the valve body for contacting/detaching the closing portion to the valve seat, and a groove is disposed on the closing portion facing the direction of a fluid flow.
