Zusammenfassung:	PURPOSE:To reduce the size of an accumulator to reduce the generation of a surge pressure during switching of a poppet type hydraulic solenoid valve for an electronic control automatic transmission for an automobile and to form the accumulator integrally with the solenoid valve. CONSTITUTION:A resilient body 15 is contractibly or expandably arranged in the vicinity of the port holes 8b and 8c of a solenoid valve. For example, a seal plate 15 comprising protrusion parts 17 and 20 capable of sealing pressure oil between ports 16 and 21 and to the outside; and thin section parts 18 and 19, formed around the port holes and resiliently deformable by a surge pressure, or a protrusion part 22 is mounted on a solenoid valve port mounting surface 8.
