 note = {The author manufactured for trial a gas sampling valve operated by oil pressure for the use of measuring the scavenging efficiency value of a two cycle engines during its operation，and 
devised a special driving system and one method of changing the time of gas collection，and basic characteristics of these operations could be made clear. The experimental result is as follows：
(1)The required valve-opening-timing can be chosen by fixing an appropriate position of
cam working, through some delay of the working of oil pressure valve accompanies，but by calculating beforehand some possible definite flank angle provided by the number of revolution and the load．(2)The oil pressure valve is simple in construction and its trouble is scarce，so it can be freely and easi1y manufactured．(3)Some suitable Bosch-type fuel jet pump can be substituted for a working pump．
(4)The valve-opening-timing can be freely chosen by devising so that the pump can be revolved on the pump shaft. The system above can be available for large size engines as well as for high speed engines．(5)For measurement of the scavenging efficiency value，it is necessary to extract at least over 20% of the effective cylinder volume．},
