摘要: A dual flush mechanism which allows the user to select either a full or partial flush, while using single valve. is obtained by first handle lifts valve actuating arm unseat in conventional manner. For second rotates and partial-flush control extends beneath arm. Upward movement of limited. Release permits rotate downwards until stopped engagement portion with transversely extending lever extension, thereby keeping an unseated position. As tank water lowers, float also pulling down end pivots so as linearly retract extension from This drop, reseating With refilling tank, rises, forcing lever, means rigid connecting member, cause pivotally attached move into pressurized contact against preparation for next cycle.
