摘要： A toilet bowl flushing device controls the rate of flow of flushing water supplied to a toilet bowl so that the toilet bowl can be washed out with a minimum amount of flushing water for a maximum flushing effect. The toilet flushing device includes a water supply system for supplying flushing water through a water supply pipe to a toilet bowl, a flow rate control valve disposed in the water supply pipe, for varying the rate of flow of flushing water supplied to the toilet bowl through control of the opening of the valve, an actuator for actuating the flow rate control valve, and a controller for controlling operation of the actuator. The controller controls operation of the actuator to vary the opening of the valve stepwise with time in one flushing cycle according to a predetermined flow rate pattern so that the flushing water is supplied toilet bowl at a flow ate which varies stepwise with time.

摘要： An automatically operating valve for regulating water flow, especially a mixing valve for automatically mixing hot water and cold water to obtain a mixed water of a desired temperature is characterized by employing piezoelectric actuators for operating valve bodies thereof. Due to such a construction, the valve can not only fully close or open but also carries out the fine flow amount control by regulating the opening rate or angle of the valve body. Especially in case the automatically operating valve is a mixing valve, the mixing ratio of hot water and cold water can be accurately regulated so that the mixed water of a desired temperature can be always automatically obtained.

摘要： In a water closet flushing apparatus of the type in which the flushing water from a flushing water supply source is fed through different flushing water feed lines to a bowl portion and a trap discharge passage defined adjacent to the bottom portion of the bowl portion, a water jet injector is provided so as to inject the flushing water jet toward the trap discharge passage, an opening-closing valve is disposed in each of different feed lines, and the operation of the opening-closing valve is controlled by a control unit. The flushing water is flushed into the bowl portion so as to clean the same while the jet of flushing water is injected into the trap discharge passage to cause the same to act as a siphon, whereby waste matter is discharged.
