    摘要: A flow rate control mechanism for use in controlling the flow rate of exhaust gases in an exhaust gas re-circulating system of an internal combustion engine. This mechanism includes a swirl flow chamber having a circular cross section, a first nozzle and a second nozzle, the former of which is open through the inner wall of the swirl flow chamber therein in the direction normal thereto and the latter of which is open through inner wall of the swirl flow chamber therein in the direction tangential thereto. The latter nozzle is positioned close to the opening of the former or first nozzle. The first nozzle directed in the normal direction extracts part of exhaust gases through an exhaust manifold, while the second nozzle directed in the tangential direction is communicated with atmosphere. The opening of the first nozzle is close to the opening of the second nozzle, so that the pressure at the opening of the first nozzle approximates the atmospheric pressure. As a result, the flow rate of exhaust gases which having been extracted through the exhaust manifold and fed into the flow rate control mechanism will be proportional to the square root of the exhaust gas pressure. On the other hand, the flow rate of intake air will be proportional to the square root of the exhaust gas pressure. Thus, the exhaust gases at a flow rate proportional to that of intake air is introduced into the swirl flow chamber, so that the both gases are mixed therein and fed into an intake manifold.

    摘要: An improved air flow direction control valve particularly adapted for use with an exhaust gas purifying system on an internal combustion engine to control the direction of flow of air to be mixed into exhaust gas for effecting additional combustion of the uncombusted constituents therein. The valve essentially comprises a pair of valve members selectively operable to open one of two main outlets and a diaphragm operated shaft for selectively operating the two valve members upon movement between a first and a second position. The shaft is formed with a pair of shoulders which define a reduced diameter shaft portion therebetween, and the two valve members encircle the reduced diameter shaft portion in an oppositely facing relation. The reduced diameter shaft portion is slidable relative to the two valve members and upon movement of the shaft axially into its first position, one of the shoulders thereof is engageable with the first valve member to open the first main outlet, while the other shoulder is engageable with the second valve member to open the second main outlet upon movement of the shaft into its second position. At least one coil spring is provided for urging either of the valve members not engaged by the corresponding shaft shoulder, into a position to keep the corresponding valve outlet closed. The valve further includes a third valve member which is resiliently supported to close an auxiliary valve outlet. According to one embodiment of the invention, the third valve member is operated independently of the shaft, while according to another embodiment, it is operationally associated with the shaft.

    摘要: In the device disclosed, a catalytic converter purifies exhaust gas from an engine. A sensor measures the temperature of the converter and an amplifier amplifies the measurement to produce a temperature signal. A differentiator produces a time-differential of the signal multiplied by a constant representing the time constant of the sensor. An operating circuit adds the multiplied time-differential to the signal to produce a voltage that is compensated for the response delay of the temperature sensor. Electromagnetic relays respond to the voltage by diverting the gases and the secondary air around the converter.

    摘要: A method for producing a magnetic recording medium wherein an undercoating layer is provided before forming a magnetic layer by applying a coating composition onto a surface of a continuously traveling flexible support, excluding widthwise-direction edge portions of the support, and pressing the support to a forward end of a slot of a coating head. At least one part of the undercoating layer is formed by preliminarily applying a high-molecular solution having a glass transition point of higher than the heat treatment temperature onto at least the edge portions of the flexible support to give a larger width to the undercoating layer than the width of the magnetic coating layer.
