The invention relates to an automobile hydraulic power steering gear which comprises a shell, a piston, a steering gear and at least two exhaust valves. The shell is provided with a containing cavity extending upwards in an inclined mode, a containing cavity communicating with the side portion of the containing cavity, an oil return channel located on the upper side of the containing cavity, and a first installation hole inclining towards the containing cavity and communicating with the oil return channel and the first cavity. The piston is installed in the containing cavity so that the containing cavity can be divided into a first cavity and a second cavity which are located at the upper end and the lower end of the piston, the first cavity is communicated with the containing cavity, and the piston is provided with a second installation hole communicated with the containing cavity and the second cavity in a penetrating mode. A rack is formed on the side portion, facing the containing cavity, of the piston. And the two exhaust valves are respectively mounted in the first mounting hole and the second mounting hole. Air in the first cavity, the second cavity and the containing cavity can be automatically and rapidly exhausted to the oil return channel through the two exhaust valves, then flows back and turns to the oil can, and then is diffused into the atmosphere.

    本发明涉及一种汽车液压动力转向器,包括壳体、活塞、转向齿轮和至少两个排气阀;壳体有斜向上延伸的容纳腔、连通于容纳腔的侧部的容置腔、位于容纳腔的上侧的回油通道、朝向容置腔倾斜、并连通回油通道和第一腔体的第一安装孔;活塞安装于所述容纳腔内,以将所述容纳腔分隔为位于所述活塞上下两端的第一腔体和第二腔体,所述第一腔体与所述容置腔连通,所述活塞贯设有连通所述容置腔和所述第二腔体的第二安装孔,且所述活塞朝向容置腔的侧部形成有齿条;两个排气阀分别安装于第一安装孔和第二安装孔。第一腔体、第二腔体和容置腔内的空气能够通过两个排气阀自动快速排出至回油通道后回流转向至油壶后散发到大气中。
