摘要： A flexible pipe unit for an exhaust pipe line of an internal combustion engine comprises a metal bellows which has a front open end adapted to be connected to a first exhaust pipe and a rear open end adapted to be connected to a second exhaust pipe. A cylindrical outer case of metal is coaxially disposed about the metal bellows in a manner to define therebetween a cylindrical space. A first structure is arranged between a front end of the outer case and a front end of the bellows to achieve a mechanical connection therebetween. A second structure is arranged between a rear end of the outer case and a rear end of the bellows to achieve a mechanical connection therebetween. At least one of the first and second structures comprises a spring member by which the bellows and the outer case are resiliently connected.

摘要： In a prior-art variable venturi carburetor in which the cross-sectional area of venturi is automatically varied according to the amount of intake air to keep the flow rate of intake air or the vacuum generated at the venturi at a constant level, since the cross section of venturi changes rectangularly, fuel is concentratedly jetted only near the middle portion of the venturi, so that fuel is not uniformly mixed with air passing through the venturi. To overcome these drawbacks, a wall having a reverse trapezoidal recess is provided near the nozzle and further a pair of triangular slots or cutouts are formed near the lower end surface of the suction piston obliquely and symmetrically so as to slidably engage with the wall, with the result that the cross section of the venturi changes trapezoidally and therefore a stable mixture is obtained even when the engine is running at a low speed or being idled.
摘要翻译：在现有技术的可变文丘里化油器中，文丘里管的横截面积根据进气量而自动变化，以将进气的流量或文丘里管上产生的真空保持在恒定水平，因为十字文氏管的一部分长方形变化，燃料集中喷射在文丘里管的中部附近，使得燃料与通过文丘里管的空气不均匀混合。为了克服这些缺点，在喷嘴附近设置具有倒梯形凹部的壁，并且在抽吸活塞的下端面附近形成一对三角形槽或切口，倾斜和对称地形成为与壁壁可滑动地接合，即使在发动机以低速行驶或空转的情况下，文丘里管的横截面也能够梯形变化，因此得到稳定的混合物。

摘要： An exhaust gas control valve includes a valve seat, a valve plate having a first exhaust gas pressure receiving area corresponding to an opening area and a second exhaust gas pressure receiving area larger than the first area; and a spring for closing the valve. In a closed state, gas pressure during a low engine speed operation acts on only the first exhaust area for shutting the opening. In an intermediate state, the pressure during a the middle engine speed operation acts on the first and second areas for opening the opening but closing the valve by overlap of wall portions of the valve plate and the valve seat overlap. In an opening state, the pressure during a high engine speed operation acts on the first and second areas for forming a gap between the wall portions to pass the gas therethrough.

摘要： A support member 10 having a tubular portion 11 is joined at an end portion of a muffler pipe 1. The support member 10 forms a flange 12 as a valve seat and a support bracket 14. The support bracket 14 has a valve disk 20 supported rotatably via a hinge axis 15. The valve disk 20 has an outer peripheral portion 12 as a contact surface with the valve seat, and a weight 30 is welded to a bead portion 23 with an inner portion thereof projecting to the back face. A spring is wound around the hinge axis, with one end 18 engaging a back face of the valve wall 21 for the valve disk, the other end engaging a support bracket. The resonance frequency is decreased by the weight, thereby preventing the beat sound from arising in a normal range of the engine speed. The weight is welded to the bead portion, thereby not causing the outer peripheral portion 23 as the contact surface to be distorted.

摘要： In a variable venturi carburetor in which the metering jet portion of fuel changes automatically according to the amount of intake air required to keep the mixture at a constant air-to-fuel ratio at all times, two series-arranged nozzles and an auxiliary fuel passage communicating with the downstream side of the venturi and with the space formed between the two nozzles additionally formed at the fixed venturi portion in such a way that the auxiliary fuel passage can be opened or closed according to engine operating conditions. Therefore, when the auxiliary fuel passage is opened, since fuel is introduced into the venturi through only a single nozzle, a rich mixture is obtained; when the auxiliary fuel passage is closed, since fuel is introduced through two nozzles, a lean mixture is obtained.

摘要： An instrument for detecting the condition of an oil is provided in which an ultrasonic wave having a predetermined waveform is propagated through the oil and assumes a change in waveform in accordance with the particular condition of the oil. The instrument includes an arrangement in which any change in the waveform of the propagated ultrasonic wave is translated into a change in terms of time involving the waveform, which is used for the detection of the particular condition of the oil.
