The plunger type oil pressure control device comprises a shell, a plunger is installed in the shell, the inner area of the shell is divided into an oil outlet cavity and an oil inlet and return cavity through the plunger, an oil inlet is formed in the side wall of the shell, the inner end of the oil inlet is communicated with the oil inlet and return cavity, and the outer end of the oil inlet is connected with an oil storage chamber; the inner end of the valve push rod extends into the oil inlet and return cavity, a through oil inlet and return channel is formed in the center of the plunger, a valve port is formed in the end, facing the valve push rod, of the oil inlet and return channel, a limiting component is arranged at the position, located at the starting point of the plunger, in the shell, and a gap is formed between the valve port and the valve push rod when the plunger and the valve push rod are both located at the starting point. An oil outlet is formed in the other end of the shell and communicated with the oil outlet cavity, and a return spring is arranged between the shell and the plunger. Oil feeding and returning are smooth, and the response speed of the working mechanism is increased.
本发明是一种柱塞式油压控制装置,包括壳体,壳体内装有柱塞,柱塞将壳体内区域分隔为出油腔和进回油腔,壳体侧壁设有进油口,进油口内端与进回油腔连通,进油口外端连接储油室,壳体一端滑动装有阀门推杆,阀门推杆内端伸入进回油腔内,所述柱塞中心设有贯通的进回油道,进回油道朝向阀门推杆的一端设有阀口,壳体内位于柱塞的起始点处设有限位部件,当柱塞与阀门推杆均位于起始点时阀口与阀门推杆之间设有间隙,壳体的另一端设有出油口,出油口与出油腔连通,壳体与柱塞之间装有回位弹簧;本发明进回油顺畅,提高了工作机构的响应速度。
