摘要： An air flow meter disposed in an intake pipe has a bypass member having a U-shaped bypass passage, into which part of air flowing through the intake pipe is introduced. An outflow port disposed at a downstream air side of the bypass passage is surrounded at its three sides by opposing surfaces of a pair of side walls and a wall surface of a partition wall disposed at “an upstream air side of the outflow port”. Further, the outflow port is opened in an air flow direction in the bypass passage and in an air flow direction in the air flow passage. Therefore, air flowing through the bypass passage is partially discharged into the air flow passage through the outflow port gradually before joining main air flow in the air flow passage, thereby restricting decrease in air flow velocity and occurrence of turbulence in the bypass passage.

摘要： A central member of a sensor unit is inserted through a sensor unit mounting hole of a cylindrical body having a main passage and the sensor unit is assembled on the cylindrical body. The sensor unit comprises the central member which is provided at the center of the main passage and has internally a bypass passage, a flow sensor provided in the bypass passage, a rib which supports the central member, a mounting section which secures the rib to the cylindrical body, an electronic circuit assembled on the rib, and a connector section retaining terminals being connected electrically to the electronic circuit section. Positioning, mounting and securing of the flow sensor can be made simultaneously by a simple process to insert the sensor sensor unit through the hole. Turbulence, eccentricity and others in the upstream air are reduced so that the flow rate of a highly rectified fluid can be measured.

An introducing port opens to the central element for introducing a part of the fluid flowing through the main passage. A branch passage is formed within the central element, through which such part of the fluid flows. A sensor is disposed within the branch passage for measuring a flow rate within the branch passage. An outlet opens to a portion of the central element located at upperstream of the downstream ends of the support elements for returning the fluid flowing through the branch passages to the main passage.

摘要： A fluid injection nozzle has an injection port plate, an injection port and a protruding portion. The injection port plate is to be mounted on a downstream end of a fluid injection valve so that a center axis thereof is coaxial to the fluid injection valve. The injection port penetrates the injection port plate between an inlet and an outlet. The protruding portion protrudes from an inner surface of the injection port to shift a direction of at least a part of a fluid flow passing through the injection port to flow in a circumferential direction of the inner surface.
