一、双作用增压器的工作原理为了使局部的油路或油达到比油泵工作压力高得多的压力,往往用增压油缸(又称增压器)来达到。双作用增压油缸的工作原理如图1所示。从油泵来的压力油p_1经管道1、换向阀、管道2至大油缸左腔,一部分油打开单向阀α经管道6至小油缸,此时柱塞向右移动,大油缸右端的回油经管道3、8至油箱,小油缸的

First, the working principle of double-acting turbocharger In order to make the local oil or oil to work pressure than the pump pressure is much higher, often with a pressurized cylinder (also known as supercharger) to achieve. Double-acting cylinder working principle shown in Figure 1. The pressure oil p_1 from the oil pump goes through the pipe 1, the reversing valve, and the pipe 2 to the left chamber of the large cylinder. A part of the oil opens the check valve α and passes through the pipe 6 to the small cylinder. At this time, the plunger moves to the right, Oil through pipes 3,8 to tank, small cylinder
