摘要：
Described herein are devices, systems, and methods for generating a variable liquid vacuum with an accompanying stable gas flow rate. In particular, when a suction device suctions a liquid and gas mixture it is advantageous to provide a variable vacuum or vacuum to apply to the liquid component while the flow rate of the gas stays constant or essentially constant.
