摘要： PROBLEM TO BE SOLVED: To reduce noise by generating turbulence downstream of a throttle valve when the throttle valve is abruptly opened. SOLUTION: A throttle body 15 is attached to an engine through an intake manifold. A throttle valve 19 provided in an internal space 16 in the throttle body 15 is composed of a shaft 18 rotatably attached to the body 15, and a disc-like valve element 17 fixed to the shaft 18. A shoulder 32 is formed in the inner peripheral wall of the throttle body 15 over the entire periphery of the latter at a position which is downstream of the shaft 18 by a distance L1 from the center axis of the shaft 18. By forming the shoulder 32 over the entire periphery, an enlarged bore part 21 having an enlarged flow passage area can be formed in the throttle body 15. The distance L1 is set to be a half of the radius R of the valve element 17.

摘要： PROBLEM TO BE SOLVED: To provide an intake manifold device in which the number of part items is reduced and which is miniaturized. SOLUTION: Covers 3a, 3b are joined with the periphery of a surge tank 6 having an interval, thereby a vacuum tank 3 can be formed. A check valve by which air is passed from a vacuum tank part 14 to only the direction of a surge tank part 15, is attached to the circumferential wall of the surge tank 6. When an internal combustion engine is operated, the surge tank part 15 is evacuated therefore, air is flowed into the tank 15 from the vacuum tank part 14 through the check valve. Air is flowed out and negative pressure stored in the vacuum tank part 14 is supplied to an actuator.

摘要： PROBLEM TO BE SOLVED: To prevent a throttle valve from being frozen even when moisture of blow-by gas is not sufficiently collected. SOLUTION: The PCV device 120 comprises a moisture separating part for separating moisture included in blow-by gas, and a communicating passage 126 for supplying an intake pipe 112 with the blow-by gas from which moisture is separated. The moisture separating part adjoins in parallel with the intake pipe 112 over a predetermined section or more to allow heat exchange between intake air flowing in the intake pipe 112 and the blow-by gas. The intake pipe 112 comprises an inclined part 160 inclined upward toward the lower reaches of intake air from the connected position of the communicating passage 126. The intake pipe 112 is provided with the throttle valve 118 downstream of the connected position of the communicating passage 126. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a resin throttle body which can suppress the distortion of bores while properly keeping sealability in a connection part to an intake manifold. SOLUTION: A resin throttle body 11, serving as a part of an intake passage, is connected to an upstream side opening of an intake manifold of an engine. The throttle body 11 has a cylindrical throttle main body 14 and an attaching flange 13 formed on a periphery of its one end. Bolt fitting holes are formed through four corners of the flange 13. The throttle body 11 is fastened to the intake manifold by means of bolts 15 through the holes. Thin portions 13a each composed of a groove M are formed on the flange 13 along the outer periphery of the throttle main body 14. Even when the flange 13 is deformed along the connection surface of the intake manifold, resultant distortion is eliminated by the thin portions 13a.
