ABSTRACT:
Fluid is forced from a reservoir into an evacuated chamber by forcing a plunger into the reservoir. When it is desired accurately to stop the flow of the fluid, the plunger is withdrawn and concurrently the pressure in the reservoir is reduced to that of the evacuated chamber by means of vacuum pump connected to the reservoir.
