PROBLEM TO BE SOLVED: To provide an autostrainer capable of connecting an inflow chamber foe making fluid flow in and a discharge chamber for discharging the fluid by a bypass, without providing a separate bypass pipe.;SOLUTION: An autostrainer 1 comprises a filter element 1, a casing 2 having an inflow chamber 11, a filter chamber 12 and a discharge chamber 13 on the inside, a first valve element 21 rotatable around a shaft 23a and a second valve element 22 rotatable around a shaft 23b. A through-hole 15 is formed in a partition wall 14 for separating the inflow chamber 11 and the discharge chamber 13, and in a state of closing a flow passage connected to the filter chamber 12 in both of the first valve element 21 and the second valve element 22, both of the first valve element 21 and the second valve element 22 open the through-hole 15 of the partition wall 14, and communicate the inflow chamber 11 and the discharge chamber 13.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
