摘要： The control system includes a motor controller (155) for controlling rotation of the motor (105) and a Host system (114) for carrying out a general control of a throttle system. A gear train (103) transmits the torque produced by the motor. A magnetic coupling (110) is provided for connecting and separating the transmission of the torque. The motor and the throttle valve are arranged in a U-shaped formation for a connection together one below the other, across the gear train. The coupling is arranged on the same side as the motor, in order to be axially aligned with it.

摘要： PROBLEM TO BE SOLVED: To provide an electronic throttle control device miniaturized on the whole. SOLUTION: In a motor 115, a stator 116 is provided with salient poles in a multiples of three, and magnetic pole sensors 119 are arranged at a set of three salient poles at the phase difference of 120 deg.. A coil 112 is a concentrated winding, and the whole of the coils is connected through Y-connection. The magnetic pole sensors 119 are arranged not at the center of the respective salient poles but in the state of being displaced in a reverse direction to the rotating direction of a rotor of the motor. The displacement angle generates torque in a forward direction except during high speed rotation which is in question, that is, even during low speed rotation if the pole sensors are arranged being displaced within a range up to an electrical angle of 30 deg. when the fundamental frequency of the motor is defined by an electrical angle of 360 deg.. Further, even in the case of a DC motor having a mechanical rectifier, a similar effect can be obtained by displacing the position of a brush by the same method.

摘要： PROBLEM TO BE SOLVED: To reduce the size of the whole of a device by a method wherein the brush of a DC motor is arranged in a position where the magnitude of generating torque is differed with a rotation direction. SOLUTION: In a motor 115, a stator 116 is provided with salient poles being a number in a multiple of three, and pole sensors 119 are arranged in a phase difference of 120 deg. at one set of three salient poles. A coil 112 is a concentrated winding and the whole of the coils is connected through Y-connection. The pole sensor 119 is arranged not at the central parts of respective salient poles but in a state to be displaced in a reverse direction to the rotation direction of the rotor of the motor. The displacement angle generates torque in a forward direction except during high speed rotation, arising a question, i.e., even during low speed rotation in a way that arrangement is effected in displacement within a range of an electrical angle of 30 deg. available when the fundamental frequency of a motor is defined by an electrical angle of 360 deg.. Further, even in a case of a DC motor having a mechanical rectifier, a similar effect is produced by displacing the position of the brush by a similar method described above.

摘要： The arrangement is intended for a unit (1) providing compensation for reduced ambient air pressure at different altitude in a carburetor. It comprises a housing (18) contg. a metering needle (28) an operating lever (19) and a bellows (13) whose free end (17) engages the lever. The pivot point (20) of the lever is adjustable relative to the needle so that the lever ratio is varialbe, this being the ratio of the distance from pivot to bellows end (17) and the distance from pivot to needle point. Adjustment of the pivot varies the relationship between the ambient air pressure and the amount of air admitted to the mixing tube in the carburettor.

摘要： PURPOSE:To suppress rise of the temperature of an electric motor for driving an air pump so as to extend the life of the electric motor by forming an air take-in passage extending to the inlet of the air pump after passing the circumference of the electric motor. CONSTITUTION:In an air pump 1 provided in such constitution that an impeller 4 is rotated in a casing 6 by means of driving of an electric motor 2 through a shaft 3 so as to raise the pressure of outside air absorbed from an air inlet 8, and the air is, for example, supplied as secondary air to the exhaust pipe of an engine, an electric motor cover 10 having an inlet pipe 9 is arranged so as to cover the circumference of the electric motor 2, and the cover 10 is assembled ingegratedly with the casing 6. An electric motor circumference air passage 11 is thus formed. When the air pump 1 is operated, air taken from the inlet pipe 9 is absorbed to be increased in its pressure through the electric motor circumference air passage 11, a housing air passage 17, a casing air passage 7, and the air inlet 8, and then, the electric motor 2 is cooled by air flow passing through the air passage 11.

摘要： PURPOSE:To prevent a change of air-fuel ratio, by providing a valve, which is closed when a low negative pressure is generated in an intake pipe, in an air passage of a carburetor, in case of the feedback type carburetor equipped with a duty solenoid provided in the air passage for correcting a slow system mixture. CONSTITUTION:Fuel from a main jet 3 and a jet 8, opened and closed by a valve of a feedback controlled solenoid 5, passes from a passage 4 through a well 2 and a main nozzle 11 being supplied to a Venturi 12 while branches from the passage 4 through a passage 14 and a slow jet 15 being supplied also from ports 20, 21. A slow system is equipped with an air bleed 16 of small contour and an air orifice 18 of large contour, which is feedback controlled, and air from the air orifice 18 passes through a passage 19. The passage 19, in which an intake pipe negative pressure is introduced by a pipe 24, is equipped with a valve 28 closed by a spring 26 when the small negative pressure is generated. When the small negative pressure is generated in an intake pipe, a reverse flow of air from the slow system to a main system is prevented.
