Abstract
A Venturi valve has a Venturi housing with a plunger slidably mounted on a control shaft within the Venturi housing. Sliding movement of the plunger along the control shaft is controlled by a compression spring. A hard stop is fixed to the control shaft to limit the movement of the plunger along the control shaft in order to keep the compression spring from over compression and from a resulting loss of accuracy.
