Patent ID: 8197221

Claim:
A pressure differential motor control for controlling the operation of a motor responsive to a pressure differential of a fluid, said pressure differential motor control comprising: a motor operable with a positive fluid pressure source assembly; an outlet fitting in fluid communication with said positive fluid pressure source assembly, said outlet fitting comprising a venturi defined therethrough along a longitudinal axis of said outlet fitting, a low pressure port defined through said outlet fitting and in fluid communication with said venturi, and a high pressure port defined through said outlet fitting and in fluid communication with an exterior of said outlet fitting; and a switch in electrical communication with said motor and in fluid communication with said low and high pressure ports of said outlet fitting, said switch being operable by a pressure differential between said low and high pressure ports of said outlet fitting; wherein said outlet fitting comprising at least a first section and a mid section adjacent said first section, said low and high pressure ports each being defined in said mid section respectively, said high pressure port further comprising a high pressure bore defined through said first section and an end face of said first section, said high pressure bore being parallel with the longitudinal axis of said outlet fitting.
