摘要： PURPOSE:To increase a soundproofing effect and to control the elevation of temperature at the front door of a cabinet by a method wherein a duct is so arranged that a soundproof wall or a soundproof space is provided. CONSTITUTION:In the case of a hanging-up-on-the wall type or a wall embedding type domestic hot water feeder, a duct 12 is housed within a space defined by the front face of a burner 9 and the front door 6a of a cabinet 6. The duct 12 is provided with a number of holes 13 and serves as an expansion type silencer. Further, a noise transmitting medium flows through the duct 12 which establishes communication between a noise generating source 9 and the outside of the cabinet 6, from an intake section 12a to a discharge section 12b as shown by the arrow B. In this case, the noise transmitting medium expands when it enters a sound absorbing material 14 through the holes 13 and contracts when it reaches the discharge section 12b of the duct 12 so that noises reduce. Further, the noises radiating from the surface of the noise generating source 9 reduce due to the existence of the duct 12 provided in the space defined by the noise generating source 9 and the front door 6a of the cabinet 6.
摘要翻译：目的：增加隔音效果，并通过一种方法来控制机柜前门温度的升高，其中管道布置成提供隔音墙或隔音空间。构成：在壁挂式或壁式嵌入式家用热水供给器的情况下，管道12容纳在由燃烧器9的前面和a的前门6a所限定的空间内管道12设有多个孔13，用作膨胀型消音器。此外，噪声传递介质流过导管12，该导管12建立噪声发生源9和机壳6外部之间的连通，如箭头B所示，从进气部分12a到排放部分12b。在这种情况下，噪声传播介质当其通过孔13进入吸声材料14时膨胀，并且当其到达管道12的排放部分12b时收缩，使得噪声减小。此外，由噪声产生源9和机壳6的前门6a限定的空间中存在的管道12的存在，从噪声产生源9的表面辐射的噪声减小。

摘要： PURPOSE: To keep the distribution of secondary air uniform and yet prevent premixture from leaking to the secondary air side by a structure wherein a secondary air chamber is partitioned by the projections arranged in the secondary air chamber into the same number of chambers as the number of secondary air passages.
CONSTITUTION: A secondary air chamber 8 is partitioned by projections 26 into three chambers 8aW8c so that the instability of the distribution of the secondary airs in the respective chambers 8aW8c to the flow holes 10 provided in the respective chambers 8aW8c due to the flow speed distribution within the respective chambers 8aW8c is dissolved. Accordingly, even when the flow rate of the secondary air changes, the distribution ratio of the quantity of the secondary air to the flow holes of the respective chambers 8aW8c can be kept constant. In addition, because burners 2 are supported by engaging both the heads 26a of rail-shape projections 26 integrally formed with a burner main body 1a and the engaging parts 27 provided on the top of the burners 2 with each other, the trouble to bolt the burners to the burner main body is saved and at the same time the leakage of premixture through the threaded holes of bolts to the secondary air side can be prevented.

摘要翻译：目的：为了保持二次空气分布均匀，并且通过这样的结构防止预混合物泄漏到二次空气侧，其中二次空气室被布置在二次空气室中的突起分隔成与数量相同数量的室二次空气通道。构成：二次空气室8由突起26分隔成三个室8a-8c，使得在相应的室8a-8c中的二次空气分配到设置在各个室8a-8c中的流动孔10的不稳定性相应的室8a-8c内的流速分布被溶解。因此，即使当二次空气的流量变化时，二次空气与各室8a-8c的流通孔的分配比也可以保持不变。此外，由于燃烧器2通过将与燃烧器主体1a一体形成的轨道状突起26的头部26a和设置在燃烧器2的顶部上的接合部27彼此接合而支撑，故将螺栓燃烧器主体的燃烧器被节省，并且同时可以防止预混合物通过螺栓的螺纹孔泄漏到二次空气侧。

摘要： PROBLEM TO BE SOLVED: To improve combustion performance by suppressing the spattering of a fuel spray while improving atomization performance to prevent a fuel from adhering to the inner wall surface of an intake pipe.
SOLUTION: This fuel injection valve comprises a plate member having a plurality of injection holes passed through therein in the plate thickness direction. At least one set of the pair of injection holes collided with each other on the downstream side of the injection holes and non-collided injection holes allowing injection in a specified direction are formed in the plate member. The set of these injection holes forms a spray structure allowing injection in two different directions (two-direction spraying). The spray structure is formed by towing the atomized spray obtained by the collided pair of injection holes by a spray with strong penetration force (lead spray) obtained by the non-collided injection hole to suppress the splash of the spray.

摘要： PROBLEM TO BE SOLVED: To solve a problem in a conventional intake device wherein control is performed upstream of an intake valve device and fuel spray sticking to the wall surface is not sufficiently prevented, and furthermore a low system cost, the atomization of fuel and short-time conveyance are required for the improvement of performance.
SOLUTION: Intake air flowing in from the intake valve device is supplied to be large in quantity (high in speed) to the ignition device side of an internal combustion engine, and flat fuel spray injected from a fuel injection valve is locally injected to the ignition device side of a shade of the intake valve device and led as a tumble flow to the ignition device while vaporization mixing is accelerated in a combustion chamber, to realize stable combustion. By the operation of a skirt for regulating an intake air flow, an intake passage formed of an intake valve and a valve seat is formed large on the side close to the ignition device and small on the side far from the ignition device, i.e., the cylinder side, and the intake flow locally with large flow is fed into the combustion chamber to effectively form tumbles.
