Conventional sealing system using the lip type oil seal is based on the concept that the forward pressure is always kept higher than the backward pressure. However, the new type of sealing system “AIRGUARD 3AS” is applied the idea that the air or lub oil always flows from the backward side to the forward side through the lip part of seal ring.<BR>We have carried out various investigation by use of test stands with #155 and #600 seal rings which is used under the backward leakage condition.<BR>As a result, the cracking pressure of seal ring and oil flow ratio of forward side to backward side are always constant in all cases. Furthermore, the lift of the lip part of seal ring on sleeve liner increases almost exponentially to the air or oil flow rate.
