摘要： A helically-shaped intake port comprising a helical portion formed around an intake valve, and a substantially straight inlet passage portion tangentially connected to the helical portion. A bypass passage is branched off from the inlet passage portion and connected to the helical portion. A rotary valve is arranged in the bypass passage and has an arm connected to a vacuum operated diaphragm apparatus. The rotary valve has a stop which is engageable with the arm. The arm is normally in engagement with the stop due to the spring force of a coil spring for retaining the rotary valve precisely at the maximum open position.

摘要： A helically-shaped intake port comprising a helical portion formed around an intake valve, and a substantially straight inlet passage portion tangentially connected to the helical portion. A bypass passage is branched off from the inlet passage portion and connected to the helical portion. A rotary valve is arranged in the bypass passage and actuated by a vacuum operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of an engine is increased beyond a predetermined value. The diaphragm apparatus comprises a diaphragm and a control rod interconnecting the diaphragm to the rotary valve. A first stop and a second stop, which are engageable with the housing of the diaphragm apparatus, are fixed onto the control rod for retaining the rotary valve at the full open position and at the completely closed position, respectively.

摘要： An elastic supporting and sealing member, for mutually supporting a first body and a second body, and for sealing the gap between the first body and the second body, includes a first portion and a second portion of wire net and a piece of thermal foaming material, between the first and the second wire net portion, which expands and foams when it is heated up. A method of making such a member includes the steps of flattening a tubular shaped piece of wire net, and of introducing a strip shaped piece of such thermal foaming material between the two sides of the flattened tube of wire net, so that the longitudinal directions of the strip shaped piece of thermal foaming material and of the flattened wire net tube substantially coincide.

摘要： A catalytic converter includes a tubular casing within which is held a monolithic catalyst body which is generally of a columnar shape. The ends of the monolithic catalyst body are each engaged with a cushion ring, and each cushion ring is engaged with a retainer ring therefor, which is substantially axially fixed within the casing near to an end thereof. The monolithic catalyst body is supported within the casing by axial compressive force present between the retainer rings on the outside, the cushion rings between the retainer rings, and the monolithic catalyst body between the cushion rings. At least one of the retainer rings is formed with a break in a part of its circumference, the two free ends of the retainer ring on the two sides of the break being movable with distortion of the retainer ring through a certain distance, according to changes of temperature of the retainer ring, with respect to one another in the mutual relative direction which causes the overall circumference of the retainer ring to be diminished, so that expansion of the retainer ring when it heats up is absorbed, and the retainer ring is not subject to kinking or folding when the catalytic converter operates in the hot condition.
摘要翻译：催化转化器包括一个管状外壳，在该壳体中保持一般为柱状的整体式催化剂体。整体式催化剂体的端部均与缓冲环接合，并且每个缓冲环与其保持环接合，该保持环基本上轴向固定在壳体内靠近其端部。单体催化剂体通过存在于外部的保持环之间的轴向压力，保持环之间的缓冲环和缓冲环之间的整体式催化剂体而被支撑在壳体内。至少一个保持环在其圆周的一部分中形成有断裂，断裂两侧的保持环的两个自由端可随着保持环的变形而移动一定距离，根据变化保持环的温度相对于彼此相对的方向，导致保持环的整个周长减小，从而吸收保持环的膨胀，并且保持环不是当催化转化器在热的条件下工作时，会发生扭结或折叠。
