摘要： A flow meter for measuring a flow rate of fluid includes a body providing a main passage through which the fluid flows. A plurality of support elements connect an inner wall surface of the body and a central element so as to support the central element substantially at the center of the main passage. 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： An air flow meter has a cylindrical housing to be coupled to an intake air conduit of a vehicle in a way that a main passage is formed within said housing. An egg-shaped member has a bypass passage formed therein is supported by a plurality of supporting members in a center of the main passage. A flow rate detecting resistance is provided in the bypass passage. There are two throttling portions formed within the cylindrical housing. A downstream throttling portion, which is provided near an outlet of the bypass passage, throttles a flow of air in the main passage near the outlet of the bypass passage so as to cause air in the main passage to be introduced into the inlet of bypass passage by a pressure difference caused thereby. An upstream throttling portion, which is provided upstream of the downstream throttling portion, throttles a flow of air in the main passage so that the flow of air in the main passage is equalized.

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.

摘要： At fuel downstream end of a valve body, there is arranged an injection port plate formed into a thin disc shape. In the injection port plate, there are formed four injection ports having fuel inlets in a common circumference on the center axis of the injection port plate. The injection ports are formed in the fuel injecting direction apart from the center axis of the injection port plate. In each injection port, with respect to the injection port axis joining the center of the fuel inlet and the center of the fuel outlet of each injection port, the injection port inner circumference more distant from the center axis of the injection port plate is more inclined toward the outer circumference with respect to the center axis than the injection port inner circumference less distance from the center axis of the injection port plate with respect to the injection port axis.

摘要： A fuel supply system is composed of a fuel rail, a fuel injection valve and a fuel filter. The fuel injection valve has an electromagnetic solenoid, a valve member, a valve guide member and a valve seat. A plurality of slanted fuel passages are formed in the surface of the valve guide to evacuate bubble from the fuel. The fuel rail is composed of a resinous upper case member and a resinous lower case member. The fuel injection valve is held between the upper and lower case members in the axial direction of the valve. An elastic sheet member is interposed between the upper case member and the fuel injection valve, and an elastic O-ring is disposed around the fuel injection valve to reduce stress applied to the fuel injection valve in installing the fuel rail to an engine.
