The piston tube is shiftably mounted in the valve body and at least in part defines an outer chamber. The flow path extends through the piston tube. The venturi element is disposed in the flow path. The vent fluidly interconnects the flow path and the outer chamber such that a pressure drop associated with fluid flow through the venturi element draws fluid from the outer chamber through the vent and into the flow path. | 09-18-2014 |
20140284508 | Venturi Valve with Hard Stop - 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. | 09-25-2014 |

The grooves are arranged in a spiral, curved clockwise or counterclockwise and crossways to the grooves of the adjacent disks, forming a number of chambers at the intersections between the contact faces of two side-by-side disks. A dynamic mixture of the incoming fluid veins through each groove is produced in each of the chambers, with the ensuing creation of local turbulence and loss in kinetic energy as heat prior to evacuation through the protruding course of the outlet grooves. The successive chambers in the course of the grooves are arranged in tiered annular spaces of gradual and controlled pressure loss. | 05-14-2015 |
