單(dan)向(xiang)打氣(qi)筒(tong)的(de)(de)(de)原理是: 打氣(qi)筒(tong)是空(kong)(kong)(kong)氣(qi)泵,通(tong)過(guo)抽拉(la)方式,將空(kong)(kong)(kong)氣(qi)吸入儲藏部位,然(ran)后通(tong)過(guo)推進(jin)(jin)方式注入或補(bu)充(chong)各種(zhong)輪胎和一些球類所(suo)需的(de)(de)(de)空(kong)(kong)(kong)氣(qi)。使用(yong)打氣(qi)筒(tong)時,要把它的(de)(de)(de)出氣(qi)管(guan)接到自行車輪胎的(de)(de)(de)氣(qi)門上,氣(qi)門的(de)(de)(de)作用(yong)是只允(yun)許空(kong)(kong)(kong)氣(qi)從打氣(qi)筒(tong)進(jin)(jin)入輪胎,不允(yun)許空(kong)(kong)(kong)氣(qi)從輪胎倒流入打氣(qi)筒(tong)。 新式外(wai)管(guan)滑動的(de)(de)(de)打氣(qi)筒(tong)就(jiu)是一個簡(jian)單(dan)的(de)(de)(de)單(dan)向(xiang)閥。當外(wai)管(guan)往上提時,空(kong)(kong)(kong)氣(qi)即從氣(qi)筒(tong)外(wai)管(guan)下端的(de)(de)(de)中(zhong)套上的(de)(de)(de)小孔進(jin)(jin)入氣(qi)筒(tong)內,這時將手柄(bing)往下壓時,氣(qi)體就(jiu)會經過(guo)設置在內管(guan)頂端的(de)(de)(de)單(dan)向(xiang)閥門進(jin)(jin)入氣(qi)筒(tong)內管(guan),順著皮(pi)管(guan)進(jin)(jin)入輪胎的(de)(de)(de)氣(qi)門。
