Operation Principles操作原则

For clockwise operation, Port 2 (P2) is open to atmosphere and air pressure is directed to Port 1 (P1). 为顺时针操作,端口2(P2)是开放的气氛和空气压力指向端口1(P1)。As the pistons move apart, the pinion rotates clockwise. 当活塞移动,小齿轮旋转顺时针。The linear movement of the pistons is converted to rotary活塞的直线运动转化为回转motion by the piston racks and the output pinion gear.运动的活塞架和输出小齿轮。

For counter-clockwise operation, Port 1 is open to atmosphere and air pressure is directed to Port 2.为逆时针方向操作,端口1是开放大气和空气压力是针对端口2。

The pressure differential moves the pistons together, rotating the pinion counterclockwise.压差移动活塞,小齿轮逆时针旋转。

For clockwise operation, Port 2 is open to atmosphere and air pressure is directed to Port 1. 为顺时针操作,端口2是开放大气和空气压力端口1。The air pressure compresses the springs and moves the pistons outward. 压缩空气压力弹簧和活塞向外移动。As the pistons move apart, the pinion rotates clockwise.当活塞移动,小齿轮旋转顺时针。The linear movement of the pistons is converted to rotary motion by the piston racks and the output pinion gear.活塞的直线运动转化为旋转运动的活塞架和输出小齿轮。

For counter-clockwise operation, Port 1 is open to atmosphere and air pressure is directed to Port 2. 为逆时针方向操作,端口1是开放大气和空气压力是针对端口2。High pressure and/or spring force moves the pistons inward, rotating the pinion counterclockwise.高压和/或弹簧力向内移动活塞,小齿轮逆时针旋转。
