摘要： A volume controllable toilet flush system, comprising: a cistern configured to hold and retain a fluid; a vertically moveable siphon assembly comprising a siphon portion, a pipe and at least one resilient element attached to the pipe; a toilet bowl shaped to retain and hold waste; an actuator operatively connected to the pipe by a stud attached to the pipe and configured to provide vertical movement to the siphon assembly, wherein movement of the siphon assembly by the actuator stores or releases energy in the at least one resilient element and, wherein downward vertical movement of the siphon assembly puts the toilet bowl in fluid communication with the cistern by creating a siphoning action between the siphon portion and the fluid in the cistern and wherein subsequent upward vertical movement of the siphon assembly terminates the siphoning action to stop fluid flow from the cistern to the toilet bowl.

摘要： An operating device includes a rotary shaft, an operating handle, an operating wire, and a drive unit; wherein this drive unit includes: a rotary member, a rotary windup member, a locking device for mutually locking the rotary member and the rotary windup member until the rotary windup member rotates in the forward rotational direction from a first operating position and reaches a second operating position, a lock release device for releasing the lock between the rotary member and the rotary windup member so the rotary windup member rotates in the reverse rotational direction and moves to the first operating position regardless of any operation of the operating handle when the rotary member and the rotary windup member reach the second operating position, and a biasing device for restoring the rotary member to an initial position at which a toilet flush operation can be started from the operating position.
