Abstract: A main steam valve includes a cylindrical guide centered about an O-axis, a valve body disposed inside the guide so as to be slidable in the O-axis direction, a valve shaft on which the valve body moves in the O-axis direction between open and closed positions, and a casing having a flow path and a valve seat formed on an inner surface thereof. The flow path guides out a fluid guided into the casing from the inflow direction along the O-axis direction. The valve body abuts against the valve seat when the valve body is in the closed position. A valve chamber, formed in the casing, has a baffle plate provided in a region between an outer circumferential surface of the guide and an inner surface of the casing. The baffle plate interrupts swirling vortex flow with spiral vortex core extending in the circumferential direction of the O-axis of the guide.

Abstract: The pole geometry of an electromagnetic switch valve includes a cylindrical well on the pole member, which is penetrated by a cylindrical pin on the magnetic armature. This obtains a magnetic force-stroke curve that first extends proportionally starting out from the initial position of the magnetic armature and then rises progressively until the magnetic armature reaches the end position. Continuously increasing the energizing of the magnetic drive upon shifting of the magnetic armature from its initial position into its end position enables the noise formation upon the closing process of the valve to be reduced. Accordingly, the noise formation upon the opening process of the valve can be reduced when the energizing of the magnetic coil is reduced not abruptly but continuously.

Abstract: An electrically-operated actuator rotates a valve toward its closing side or opening side. A valve urging part urges the valve from a fully-closed position toward the opening side. An ACT control part controls the electrically-operated actuator to drive. A set load of the valve urging part is smaller than a set load that is capable of returning the valve from a fully-closed position to an intermediate position only by urging force of the valve urging part. When a position of the valve at time of turning off an IG switch for stopping operation of an internal-combustion engine is on the closing side of the intermediate position, the ACT control part shifts the valve to the intermediate position by the electrically-operated actuator after the IG switch is turned off.
