    • PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of preventing a desired flow rate of injected fuel from not being attained, by preventing a distance between an armature at non-energization time to a coil and a core from becoming narrower than a desired distance when mounted on an engine. SOLUTION: This fuel injection valve includes the coil 1, the core 2 having an end part arranged inside the coil 1, a body 3 having an end part fixed to the end part of the core 2, a housing 4 arranged outside the coil 1 and allowing one end part side to abut on a cylinder head 6 of the engine, a cap 5 arranged on the other end part side of the housing 4 and allowing the anti-housing 4 side to abut on a fixing means 7, and the armature 9 reciprocatably arranged inside the body 3 and attracted to the core 2. A first clearance 8 is formed between the housing 4 and the body 3, and the cap 5 and core 2 are fixed, and the housing 4 is allowed to abut on the cylinder head 6, and the fixing means 7 is allowed to abut on the cap 5, and is mounted on the engine.

    • PROBLEM TO BE SOLVED: To provide an intake device reducing manufacturing man-hour and method for manufacturing the same. SOLUTION: A plurality of valve units 20 are formed as one unit by simultaneously inserting a shaft 30 and a bearing member 40. Consequently, forming and assembling for each valve unit 20 and insertion of the shaft 30 into each valve unit 20 are made unnecessary when the intake device composed of the plurality of the valve units 20 is assembled. The bearing member 40 includes a knurled part 42 regulating movement of a housing 21 and a shaft 30 includes a blocked part 32 regulating movement of a butterfly 22. Consequently, expansion and contraction of the resin made housing 21 and the butterfly 22 accompanying temperature change are generated with keeping origins on the knurled part 42 and the blocked part 32 and dimension change is absorbed in single valve unit 20 not to affect the adjoining other valve units 20.

    • 要解决的问题:提供减少制造工时的进气装置及其制造方法。 解决方案:通过同时插入轴30和轴承构件40,多个阀单元20形成为一个单元。因此,对于每个阀单元20的形成和组装以及将轴30插入每个阀单元20中 当由多个阀单元20构成的进气装置组装时,不必要。 轴承构件40包括限制壳体21的运动的滚花部分42,并且轴30包括限制蝶形件22运动的阻挡部分32.因此,伴随温度变化的树脂制壳体21和蝶板22的膨胀和收缩是 在滚珠部分42和阻挡部分32上保持起点产生的尺寸变化被吸收在单个阀单元20中,而不影响相邻的其它阀单元20.版权所有(C)2007,JPO&INPIT
