摘要： A torque-transmitting device is advantageously applied to a secondary air control valve mounted on an automotive vehicle. The device includes a gear train for reducing a rotational speed of a motor and a mechanism for converting a rotational motion to a linear motion of a valve shaft. The gear train includes a final gear coupled to the valve shaft, and the final gear includes a flange positioned at an axial end of an axis of the final gear. A coil spring for biasing the final gear toward a predetermined position is disposed next to the flange and around the axis of the final gear. Slits or holes are formed through the flange, so that holding jigs for holing the coil spring are inserted, in an assembling process, into a cylindrical space between an inner circumference of the coil spring and the axis of the final gear.

摘要： An air control device is advantageously used as a device for supplying secondary air to a catalyzer contained in an exhaust pipe of an internal combustion engine. The air control device includes an electric motor, a speed reduction mechanism, a valve having a valve shaft and a biasing spring. These components are all contained in a housing that has a valve port formed therein. The valve is driven to open the valve port by the electric motor against a biasing force of the biasing spring. A rotational movement of a final gear in the speed reduction mechanism is converted into a linear movement of the valve shaft to thereby open the valve port. Since the biasing spring such as a torsion spring is wound around a flange connected to an axis of the final gear, a length of the valve shaft is made short, and the device as a whole is made compact.

摘要： A secondary air pressure detecting apparatus includes a solenoid valve and a pressure sensor. The solenoid valve defines a secondary air passage that introduces secondary air from the air pump into the exhaust system of an engine. The solenoid valve opens and closes the secondary air passage. The pressure sensor is integrally mounted to the solenoid valve to detect pressure of secondary air in the solenoid valve. The solenoid valve includes a coil assembly and magnetic members. The coil assembly includes a solenoid coil that generates magnetic force when the solenoid coil is energized. The magnetic members construct a magnetic circuit with the solenoid coil. The magnetic circuit is arranged outside of the secondary air passage. The pressure sensor is arranged on an opposite side of the secondary air passage with respect to the magnetic circuit.

摘要： A fluid control valve assembly is disclosed that includes a housing. The housing defines an inlet pipe and a valve port in fluid communication with the inlet pipe, such that a fluid passes from the inlet pipe and through the valve port. The inlet pipe defines an inlet pipe axis and the valve port defines a valve port axis. The fluid control valve assembly also includes a valve movably supported within the housing. The valve includes a valve head for opening and closing the valve and a valve shaft coupled to the valve head. The valve shaft defines a valve axis that is coaxial with the valve port axis. The inlet pipe is orientated toward the valve port such that a positive, acute angle is formed between the inlet pipe axis and a plane perpendicular to the valve axis.
