    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.

    摘要： An object is to provide a solenoid valve device that can quickly move an armature and can more reliably inhibit penetration of contaminants. A solenoid valve unit (3) is provided with a breathing hole (6h) extending in a radial direction through a sleeve (6) on a side of a solenoid portion (10) and bringing a space (A), which is formed between an armature (34) and a spool (7) when the armature (34) is at least in a predetermined region, into communication with the outside, a first opening (11d) facing a side of a valve portion (5) and opening to the outside, a second opening (11h) opening to the outside, and a breathing channel in a solenoid case (11), the breathing channel communicating at an end thereof with the first opening (11d) and communicating at an opposite end thereof with the second opening (11h). The solenoid valve unit (3) and the valve housing (2) are fixed together with an annular seal (40,11k) being interposed around the sleeve (6) so that a passage between the breathing hole (6h) of the solenoid valve unit (3) and the first opening (11d) is ensured and a passage between the breathing hole (6h) and the outside is cut off.
