ABSTRACT:
A vacuum controlled liquid metering assembly is provided defining an upstanding fluid passage therethrough communicated with the source of fluid at its lower end and with a source of variable vacuum at its upper end. A plurality of valve members are freely reciprocal in the passage between upper and lower limit positions and each is loosely received in the passage. In addition, each of the valve members has an upstanding bore formed therethrough and the bores of the valve members are vertically aligned. The valve members are of different weight with the heaviest valve member disposed lowermost and the lightest valve member disposed uppermost. Also, the diameters of the passages or bores formed through the valve members are each larger in diameter than the bore or passage disposed immediately thereabove. Still further, the valve members may be buoyed up in their confining upstanding fluid passage in response to greater fluid pressures therebelow and dynamic fluid pressures acting upon them from therebelow.
