摘要： PROBLEM TO BE SOLVED: To provide a low leak air valve assembly for an intake manifold. SOLUTION: In this valve, by mounting a butterfly valve on a rotational axis a low leak air valve assembly for an intake manifold is constituted. The butterfly valve comprises a first wing 32 having a first elastic seal means 36 and a second wing 34 having a second elastic seal means 40. The first elastic seal means 36 has a projecting lip 38 brought into contact with a shelf portion 26 of a port 18 to seal the shelf portion 26. The second elastic seal means 40 has a beam portion 42 brought into contact with a shoulder portion 28 of the port 18 to seal the shoulder portion 28. At both sides in an axial direction of a passage 30 of the butterfly valve, third elastic seal means are arranged. Forming an area of a first region 54 to be larger than that of a second region 56 increases sealing force of the valve.

摘要： PROBLEM TO BE SOLVED: To make a motor-driven throttle assembly compact and lightweight, to improve responsiveness and to dispense with calibration after installation. SOLUTION: A throttle valve assembly 110 is provided with a throttle shaft 18 with a part extended outward from a throttle body 12, and a rotor 166 is fitted to the extended part. A housing 80 surrounds the rotor 166 concentrically, and a stator 134 is fitted to the rear wall 86. The stator 134 is provided with pole pieces 136, 138, and cantilever-fitted to the rear wall 86 concentrically on a shaft 92 inside the rotor 166. The cylindrical rotor 166 with magnets 172, 174 has a flange 168 and a hub 170, and the hub 170 is connected to one end of the extended part of the shaft 18 in the state of the rotor 166 being placed over the pole pieces 136, 138 of the stator 134. As the fitting direction of the rotor magnets 172, 174 and stator pole pieces 136, 138 to a valve member 16, is fixed, calibration after assembly is dispensed.

摘要： PROBLEM TO BE SOLVED: To provide a throttle valve assembly, a torque motor assembly and a manufacturing method for increasing a winding area of a thin plate laminated body relative to the predetermined dimensions of a motor. SOLUTION: The motor-driven throttle valve assembly 110 is provided with a shaft 18 having an extending part arranged on the outside of a throttle main body 12, a hollow rotor 166 mounted on this extending part, a stator 134 coaxially arranged inside the rotor, mounted on the outer wall 86 having a plurality of magnetic pole parts wherein coils are spaced in a peripheral direction. The inner peripheral surface of the rotor is opposed to the outside of the magnetic pole of the stator, and a plurality of magnets 17 and 174 are arranged on this inner peripheral surface. The extending part of the shaft is mounted on a flange part 168 of the rotor for rotating and driving the rotor. Instead of shortening the dimensions of the motor or dispensing with a mounting shaft, more winding areas for conductive coils are given by welding, winding and integrating by a mold coating, and lines of magnetic force are increased.

摘要： A low-leakage air valve assembly 10 for an air intake manifold 16 includes a butterfly valve 12 constructed for mounting on a rotatable shaft 14. The butterfly valve 12 includes a first 32 and a second wing 34 with first elastic sealing means 36 mounted about the periphery of the first wing 32, and second elastic sealing means 40 mounted about the periphery of the second wing 34. The first elastic sealing means 32 includes a projecting lip 38 for sealingly contacting the wall of the valve manifold 16. The second elastic sealing means 40 includes a beam portion 42 for sealing contact with shoulder 28 of manifold 16. Third elastic sealing means 44 is axially positioned at each side of the passage 30 in the butterfly valve 12 and radially provided around a portion thereof. The first area 54 defined by the first sealing surface which is the first wing 32 and first elastic sealing means 36 is larger than the second area 56 defined by the second wing 34 and second elastic sealing means 40. This provides a net torque which increases the sealing force of the valve.

摘要： An electrically operated throttle valve assembly 110, 210 having a throttle shaft 18, 218 with a portion extending exteriorly of the throttle body 12. Rotor 166, 266 is mounted on the extending portion of shaft 18, 218. A housing 80 concentrically surrounds the rotor 166, 266 and includes a rear wall 86, 286 to which stator 134, 234 is attached. The stator 134, 234 having a plurality of circumferentially spaced pole segments each with a coil is mounted to the rear wall 86, 286 and is concentrically disposed within the rotor 166 , 266. The hollow cylindrical rotor 166, 266 with plural magnets 72, 74, 272, 274 disposed about the inner periphery has a radial web flange 168, 268 whic h is drivingly attached to one end of the extending portion of shaft 18, 218 with the rotor 166, 266 nested over the stator pole segments. Reducing the size o r even eliminating the mounting shaft or bolt 92, and preferably replacing it with a welded, wound and overmolded stack of laminations provides more winding area for electrically conductive coils to provide more magnetic flux.
