Abstract: An exhaust valve for a bag comprising a valve body having an exhaust opening communicating with a part between the inner and outer surfaces of the bag, a lid body detachably fitted to the valve body having a suction opening, a valve plate arranged above the upper end of the exhaust opening to move up and open the exhaust opening at the time of exhaust of the bag and to move down and close the opening the exhaust opening after the aeration of the bag, and a lock mechanism for keeping the exhaust opening closed and for allowing the valve plate to move up and down.

Abstract: A rotator with an impeller and a stator generating an induced voltage are arranged in a casing. The tap water flowing flows through a main passage, which has a first jet orifice facing the impeller, and rotates the impeller. A bypass running from the inflow port and passing around an outer periphery of the stator is provided. When the water pressure is high, a check valve closing the bypass is opened against a spring force and the water flows out to a drain port, while the impeller is stably rotated by a pressure of water jetted from a second jet orifice penetrating from the bypass to face the impeller, which pressure is in reverse proportion to a speed of flow inside the bypass.

Abstract: A movable lid is mounted to a valve body movably in an up-and down direction toward and away from the valve body whereby the valve body is lowered to be open against force of a spring by pressing a suction nozzle of an electric vacuum cleaner onto the movable lid and at the same time an exhaust of a bag may be carried out. After the exhaust, by moving the suction nozzle away from the movable lid, the movable lid may be moved upwards to place its original position the restoring force of the spring, so that the valve body may be opened.
