摘要： In the region in which a coil and a connector are provided, the leakage of a fluid to which coil and connector is prevented by a seal member, a passage extending from the seal member to a position in the vicinity of a terminal of the connector is formed. At the time of completion of the production of a solenoid valve assembly, an air-tightness test on the seal member can be conducted directly through the passage, so that the detection of damage to the seal member, the detection of bite into the seal member, the detection of a defect of the seal member and so on can be carried out at the time of completion of the production of the mentioned assembly. Namely, the detection of the sealability of the seal member is rendered possible.

摘要： Provided is a solenoid valve stable in response performance, whose quickness and damping performance are appropriate. In the solenoid valve, a respiration port (46) to be used for flowing fluid into and out from a space located on one side of a plunger (24) that faces the spool (60) is formed in an end portion of a valve sleeve (41) that faces a solenoid case (21). Further, in the solenoid valve, a respiration groove (66) is formed on the spool (60), wherein the respiration groove (66) causes the space located on the one side of the plunger (24) facing the spool (60), and the respiration port (46) to communicate with each other when an end portion of the spool (60) that faces the plunger (24), and an end portion of a center post (27) that faces the spool (60) are in contact with each other with the spool (60) having been put in the nearest possible position to the plunger (24). This configuration makes it possible to discharge, with an appropriate level of flow-channel resistance, fluid placed in the space located on the side of the plunger (24) facing the spool (60). Therefore, slowdown of the response performance does not occur, and appropriate damping performance is ensured.
