type: PURPOSE
Source sentences:
text: Whereas known multiple tap aspirators may require suction flow to pass through multiple check valves (e.g., multiple check valves arranged in series or arranged in a common passage between the junctures of suction passages with the common passage), the depicted arrangement advantageously requires suction flow to pass through only a single check valve as it travels from a source of suction flow to the aspirator via one of the suction passages, thereby reducing flow losses which may result from flow through multiple check valves.
