Tesla valve. Think about that for a moment. It is a one way valve that has no moving parts. Tesla turbines are primarily concerned with laminar flows steady flows and work better at higher pressures.
Nikola teslas valvular conduit is another one of his forgotten inventions. The device is named after nikola tesla who was awarded us. One way flow with no moving parts heres yet another delightful mechanical curiosity from among nikola teslas 278 known patents.
Materials at the time were pretty bad and valves were unreliable. What makes it special is the fact it has no moving parts. A pulsejet expels exhaust and intakes air through the same hole so good ones.
Patent 1329559 in 1920 for its invention. Based on munros previews this definitely seems to be the. A tesla valve called by tesla a valvular conduit is a fixed geometry passive check valve.
Invented in 1920 it has largely been overlooked. The tesla valve is a passive type check valve used for flow controlrectification in a variety of micromini channel systems. Tesla the inventor not the car invented a lot of things including a one way valve design with no moving parts.
This one is 1329559 us valvular conduit issued 1920. Tesla figured that by removing any moving parts from a valving mechanism he could create a simpler and more robust valve. Experiments show that the tesla valve on the other hand works best with pulsed flow.
Unfortunately for us nikola tesla declared bankruptcy a month after filing the patent and as a result the valve faded into history and has seen little or no usage since. It allows a fluid to flow preferentially in one direction without moving parts. In simple terms it is a one way valve.
