Abstract
One pressure difference detection connecting path (71) and another pressure difference detection connecting path (72) are formed so as to be arranged at a predetermined interval in a longitudinal direction. Further, the one pressure difference detection connecting path (71) is formed so as to be connected in front of a continuation center position (70) of a second inflow path (67) and a first inflow path (43). Further, the other pressure difference detection connecting path (72) is formed so as to be connected behind a continuation center position (69) of a second outflow path (66) and a first outflow path (44).
