To automatic reversing valve, high frequency, fast response speed and no hydraulic impact for the commutation, low noise are contradictory. In order to improve automatic reversing valve reversing frequency and reduce commutation delay time, and to ensure the stable reliable reversing without hydraulic clamping and hydraulic impact phenomena, a quick reversing electric valve for artificial heart was designed and made. The theoretical analysis shows that by changing the hole size, this quick reversing electric valve can be applied in many occasions. Experiments show that when the commutation frequencies are 24 and 82 times/min, using the fast reversing valve, the artificial heart blood pressure waveform is stable. It is shown that the stable and reliable fast directional valve can apply to high frequency occasions such as artificial heart.
