限压阀可循环油路中的油压，防止机油过多窜入燃烧室、机油耗量增加，发动机工作出现不正常现象。同时也为了避免油压过高，造成管路及滤清器。限压阀是靠弹簧的压力来控制油压的单向阀。当油路中油压大于弹簧压力时，则阀球打开，部分机油流回油底壳，于是油路卸压。它一般安装在机油泵或主油道上。 传统油箱盖的工作原理与散热器盖相似，FE2 GK其上至少有一个限压阀，例如采用空气一蒸气阀来平衡燃油箱内外的压力。随着油箱内燃油的逐渐消耗，油面不断下降，在油面上方形成负压，当真空度达到一定程度时，油箱盖的空气阀（即进气阀）被压力推开LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=3%3A32%2C4%3A32%2C8%3A134217728%2C9%3A134250632%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=0&pra=5&wgl=1&uach=WyJXaW5kb3dzIiwiNy4wLjAiLCJ4ODYiLCIiLCI5OC4wLjQ3NTguMTAyIixbXSxudWxsLG51bGwsIjY0IixbWyIgTm90IEE7QnJhbmQiLCI5OS4wLjAuMCJdLFsiQ2hyb21pdW0iLCI5OC4wLjQ3NTguMTAyIl0sWyJHb29nbGUgQ2hyb21lIiwiOTguMC40NzU4LjEwMiJdXV0.&dt=1645404977213&bpp=1&bdt=32&idt=28&shv=r20220216&mjsv=m202202090102&ptt=9&saldr=aa&cookie=ID%3D138bd4a5c3f9dd5c-22e6327ab7c8007c%3AT%3D1621323454%3ART%3D1621323454%3AS%3DALNI_MZr6w-L6tDY0HVf8PxDU64fYTf-Jg&nras=1&correlator=1701627631362&frm=23&ife=1&pv=1&ga_vid=1570419461.1645404977&ga_sid=1645404977&ga_hid=1125224163&ga_fc=0&nhd=1&u_tz=480&u_his=24&u_h=1080&u_w=1920&u_ah=958&u_aw=1920&u_cd=24&u_sd=1&DMC=8&adx=-12245933&ady=-12245933&biw=1920&bih=855&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42531397%2C44750773%2C182982000%2C182982200%2C21067496%2C31062931&oid=2&pvsid=3080424429233066&pem=146&tmod=875727929&uas=0&nvt=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C958%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.5s6fmsmp6w1x&fsb=1&dtd=33" data-google-container-id="1.5s6fmsmp6w1x" data-load-complete="true"> 汽油喷油器 23209-62020 喷油器 095000-0260 洋马轴 158560-51440 控制阀 7135-588 喷油器 20430583 喷油器 3155040 喷油器 387-9432 C9 单体泵 04287049 油嘴 DOP152P522-3898 喷油器 212-8470 喷油器 221-9915 喷油器 0 446 116 059 计量阀 0360-04M28 泵总成 8-97605946-8 294050-0424 溢流阀 7403095479 喷油器 100-7562 电磁阀 2490713 喷油嘴 G3S52 喷油嘴 G3S10 |
