摘要： An air flow rate measuring device serves to measure a flow rate of air flowing through a main passage inside an intake pipe of an engine. A base has its one end directed axially of the main passage toward an upstream side of air flowing therein, and its other end directed toward a downstream side thereof, with a bent groove being formed in the base. A circuit module includes a support substrate and a detection element installed one surface of the support substrate for detecting the flow rate of air, the module being joined to the base in a face-to-face relation with respect to each other to form an auxiliary passage in cooperation with the groove. The detection element on the one surface of the support substrate is exposed to air in the auxiliary passage, and the other surface of the support substrate is exposed to air in the main passage.

摘要： A highly accurate thermosensitive flow rate sensor is able to reduce the detection error of a flow rate even in the case of a flow accompanied by considerable intake air pulsation in an automotive engine or the like. A flow rate detecting section disposed in a main pipe is equipped with a support member having a first guide surface and a second guide surface for guiding a fluid on opposite sides thereof, and a flow rate detection element provided on the second guide surface of the support member. The second guide surface of the support member, on which the flow rate detection element is mounted, extends longer than the first guide surface in the downstream direction.

摘要： A flow rate sensor comprises: a main fluid passage for a fluid to flow therealong; a detecting pipe conduit coaxially disposed in the main fluid passage; a temperature sensing element for sensing the temperature of the fluid; a flow rate sensing element including a flow rate detecting resistance made of a thermo-sensitive electrically resistant material, the flow rate detecting element being disposed in the main fluid passage in a manner such that the flow rate detecting resistance is exposed to the fluid flowing therethrough; and a control circuit for controlling an electric current flowing to the flow rate detecting resistance such that the temperature of the flow rate detecting resistance may be maintained at a predetermined value which is higher to some extent than a fluid temperature detected by the temperature sensing element. The main fluid passage involves a converged section whose passage cross sectional area becomes gradually smaller towards the downstream side thereof. At least one portion of an inner surface of the converged section cut by a plane containing the central axis of the main fluid passage is formed by a generally three dimensional curved surface. The inlet of the detecting pipe conduit is disposed in a direction in which the fluid flows, in a manner such that the inlet of the detecting pipe conduit is at a position close to the narrowest portion of the passage cross sectional area of the converged section.

摘要： An air intake system for an internal combustion engine which does not impair detection performance of a flow sensor without impairing intrinsic function thereof even when a distance between the flow sensor (4) and as inlet port (80) for a recirculating air is dimensioned short. The air intake system includes a recirculating air passage (8) for recirculating a blow-by gas (B) leaking into a crankcase (13) connected to an engine cylinder (1) to an intake air passage (2a). A positive crankcase ventilation system is provided which includes a communicating passage (18) for communicating interior of the crankcase (13) with that of a head cover assembly (14) of the cylinder (1), a recirculating passage (6) for introducing the blow-by gas (B) from the head cover assembly (14) into an intake air passage (2a) at a location downstream of a throttle valve (24), and a recirculating air passage (8) for introducing the recirculating air into the head cover assembly (14) from the intake air passage (2a) at a location intermediate between the flow sensor (4) and the throttle valve (24). The recirculating air passage (8) has a suction member (81) having one end portion disposed within the intake air passage (2a). The suction member (81) defines an air inlet passage having an inlet port (80) provided in the one end portion located at a downstream side relative to the center of the one end portion within the intake air passage (2a). Disturbance in the air stream occurring at the flow sensor is suppressed. Besides, protecting the flow sensor is protected against contamination even when the blow-by gas injected from the recirculating air passage (8).
