Which is the air inlet and exhaust port of the cylinder?

1. The so-called intake control or exhaust control refers to the direction of the one-way throttle valve connected to the air inlet of the cylinder. 2. Generally, the exhaust throttle is used to control the double-acting cylinder, that is, to control the air flow at the outlet of the cylinder, which is beneficial to control the stability and linearity of the cylinder speed and is not easy to crawl. 3. When controlling nozzle flow and single-acting cylinder, intake throttle control is usually adopted. The judgment of intake throttle and exhaust throttle mainly depends on the direction of one-way valve in the schematic diagram, as shown in the figure, the intake throttle is on the left and the exhaust throttle is on the right.
