Abstract
A fuel-feed system for engines, gas turbines, burners and the like, including a fuel pressure source communicated with a fuel tank and a porous piezoelectric ceramic filtering element, such as barium titanate, connected to a generator of electric oscillations and placed into a housing which inlet and outlet are separated by said element. The latter can be shaped as a hollow needle of a fuel-injector valve, said outlet equipped with a valve seat interacting with a free end of said element.
Claims2
A fuel-feed system for engines, gas turbines, burners and the like, including a fuel-pressure source communicated with a reservour means and a flow-line filtration system comprising a housing having a fuel inlet port and a fuel outlet port, a porous piezoelectric ceramic filtering element having working surfaces thereon and located in the housing in the flow path of the fuel, partitioning the housing into an input part and an output part, a metallic coating on said working surfaces, and a generator of electric oscillations connected to said metallic coating whereby foreign matter in the fuel is removed by the filter and vibration of the filter effected by the generator of electric oscillations prevents clogging of the filter and emulsifies the fuel.
