摘要： A proportional type electromagnetic valve comprises a flow rate control valve secured to a movable core which moves a stroke in proportion to the input current, and a valve seat portion cooperative with the flow rate control valve to control the flow rate. In addition to a bias spring providing for urging the flow rate control valve toward the valve seat portion, a second spring is disposed on the movable core for urging the flow rate control valve to release it from the valve seat portion. The resultant force of the two springs makes the stroke of the flow rate control valve proportional to the input current.

摘要： Automotive engine idle speed control device meters the flow rate of air supplied to the engine bypassing an intake pipe thereof during engine idle operation to thereby control the engine idle speed. An actuating vacuum is produced in accordance with an electrical signal and acts on a diaphragm fixed to a valve movable with the diaphragm to meter the bypass air flow. To cancel any external force acting on the valve, adjusting means is provided to control the vacuum on the diaphragm independently of the electrical signal to displace the diaphragm in a direction opposite to the direction of action of the external force on the valve.

摘要： An idle speed control device has an electromagnetic driving portion and a flow rate controlling portion disposed in a bypass passage formed in a throttle chamber such as to bypass a throttle valve. The flow rate controlling portion has a body defining a passage for the fluid to be controlled, a seal formed in an intermediate portion of the passage, a first valve driven by the plunger of the electromagnetic driving portion through a rod such as to be brought into and out of contact with the seat, a sleeve disposed in the body, and a second valve connected through a rod to the downstream side of the first valve such as to produce a vacuum force which acts in the opposite direction to the vacuum force produced on the first valve thereby to absorb any fluctuation in the intake pressure in cooperation with the first valve, the second valve being loosely received by the sleeve. According to this arrangement, it is possible to eliminate any unfavorable effect of the fluctuation in the intake vacuum on the actual air flow rate. In addition, since the flow from the vacuum compensating portion is minimized, the vacuum compensation is made possible without incurring any increase in the initial leak.

摘要： The output of an oxygen concentration detector monitoring the conditions of exhaust gases from an internal-combustion engine is not a linear function of the concentration but varies widely. When feeding this output back to control the air-fuel ratio of the mixture being fed to the engine, the feed back system having the small time constant (small delay time in operation) becomes unstable due to the nonlinear output of the oxygen concentration detector. In order to stabilize the operation of the system the output of the oxygen concentration detector is input to compensating circuit which outputs the voltage being proportioned to the oxygen concentration of the exhaust gas and the output is used as the feedback signal.
