Energy storage in air bag increases, and the pressure in liquid storage cylinder, air storing cavity accordingly increases, the initial longitudinal direction of the flippers or bionic caudal fin
Bending stiffness is bigger, conversely, then the initial longitudinal bending stiffness of the flippers or bionic caudal fin is smaller, initial buckling is rigid
The i.e. default longitudinal bending stiffness of degree.
During the preceding paragraph is fallen, when swimmer swings the flippers or bionic caudal fin, the paddle blade, fin keel or longitudinal keel
Shape changes during upper and lower bending, and the volume of the liquid storage cylinder or air storing cavity accordingly changes, pressure rise；
Among the action of swinging kick of swimmer, the gas in liquid or air storing cavity in liquid storage cylinder is forced through under pressure
The throttle orifice of inner elements of check valve flows, when the secondary swaying legs action terminates and starts reversed swinging kick, the liquid in liquid storage cylinder
Or the pressure of the gas in air storing cavity is down to minimum, by the positive back pressure for having accumulator to be provided, the spool of check valve is opened
It opens, moment squeezes into the extra liquid or gas within accumulator and except air bag in liquid storage cylinder or air storing cavity, inside and outside spool
Pressure at both sides reaches balance, and spool resets under the elastic force effect for the reseting elastic element that check valve itself is carried closes；With
Frequency or the rate for swimmer's swinging kick are higher, and liquid or gas pass through the flow velocity of the throttle orifice flowing on spool higher, damping
Effect is more apparent, and the pressure difference inside and outside spool is higher, and the paddle blade, fin keel or longitudinal keel resist the energy of flexural deformation up and down
Power is stronger, and the longitudinal bending stiffness of the flippers or bionic caudal fin is bigger, to improve trip speed and still be protected under height trip speed
Hold higher propulsive efficiency；Conversely, the frequency or rate with swimmer's swinging kick are lower, the paddle blade, fin keel or longitudinal keel
The ability for resisting flexural deformation up and down is weaker, and the longitudinal bending stiffness of the flippers or bionic caudal fin is smaller, to reduce trip
Speed simultaneously still maintains higher propulsive efficiency under low trip speed；It is in brief, higher with the frequency or rate of swimmer's swinging kick,
The flippers or bionic caudal fin it is more apparent with fast automatic variation rigidity characteristic, the propeller power of the flippers or bionic caudal fin is got over
Greatly, i.e., the described flippers or bionic caudal fin have speed changing function.
It is filled with non-newtonian flow in liquid storage cylinder in the paddle blade, fin keel or the hollow Taper Pipe of longitudinal keel or in air storing cavity
