摆线转阀式全液压转向器具有结构紧凑、重量轻,操纵轻便、维修简单等优点。因此,近年来广泛地应用于轮胎式工程机械(如挖掘机、装载机、推土机、平地机、铲运机、起重机)、农业及林业机械、起重运输机械、矿山机械、船舶及大型操作机等。1979年我厂研制了YZC-920型摆线转阀式全液压转向器(图1),其额定工作压力为160公斤/厘米_2,排量为920毫升/转。并成功 Cycloid rotary valve hydraulic steering gear with compact, light weight, easy operation, easy maintenance and so on. In recent years, therefore, it has been widely used in tire-type construction machinery such as excavators, loaders, bulldozers, graders, scrapers and cranes, agricultural and forestry machinery, hoisting and transport machinery, mining machinery, ships and large- Wait. In 1979, our factory developed a YZC-920 cycloidal rotary valve hydraulic steering gear (Figure 1), the rated working pressure of 160 kg / cm_2, displacement of 920 ml / rev. And succeeded
