A solenoid valve mechanism includes a cooperating poppet and valve seat and a first bias spring for urging the poppet into sealing engagement with the valve seat. A solenoid armature carries the poppet and includes means for selectively urging the poppet against the spring bias. A solenoid coil cooperates with the solenoid armature and the armature is provided with a fluid seal and a second bias spring for urging the armature into position at which the fluid sealing means forms a fluid seal around the valve member. The fluid seal includes a path for bleeding fluid across the valve seat.
