ABSTRACT:
Vacuum systems for use aboard aircraft and other vehicles, wherein, by simplified design, the systems of this new invention are virtually foolproof. This new invention utilizes the age old venturi due to its simplicity and lack of moving parts, but due to innovation, the limitations of the venturi have been overcome. This new invention installs the venturi within the exhaust tailpipe of engines and puts the extreme high velocity of exhaust gas movement to good use. These systems are compatible with just about any engine, and obviously venturi ice problems are eliminated. These systems may be used to provide redundant power for gyro systems and windshield wiper systems. By the addition of a suction relief valve and connective tubing the system will provide regulated suction pressure for the operation of a Gyro Horizon and or a Directional Gyro. By further addition of a restrictor needle valve and additional connective tubing, one can power either a Turn and Bank indicator or A Turn Co-ordinator. By the simple addition of a speed control needle valve, one may power a set of vacuum motor driven windshield wipers. The venturis and adjacent connective tubing will require the use of special alloys so as to survive high temperature encounter. Vacuum pressure will become available immediately following engine start up. These systems are suitable for use on airplanes, helicopters, blimps, dirigibles, boats, trucks, earth moving equipment, tractors, automobiles and the like but not restricted thereto. They also work well on Brake Booster Servo units, such used on power brake systems of automobiles. Some autopilots operate by means of vacuum power therefore compatible to these new systems.
