Abstract:
1. An apparatus for generating high-speed fluid jets, the apparatus comprising: a valve body having a valve cavity, an inlet, and an outlet, a valve shuttle slidably mounted with respect to said valve body within said valve cavity, said valve shuttle dividing said valve cavity into a first cavity and a second cavity, said valve shuttle movable between a closed position and an open position with respect to a valve assembly, said valve shuttle having a fluid passage, in said open position said fluid passage in communication with said outlet, said first cavity and said second cavity, in said closed position said valve shuttle preventing communication between said inlet and said outlet, said valve shuttle oscillating between said open position and said closed position when pressurized fluid flows through said valve assembly, the pressurized fluid inside said valve assembly urging said valve shuttle to move alternatively between said open position and said closed position, said inlet communicating with said first cavity, said outlet communicating with said second cavity, said fluid passage communicating with said outlet, said second cavity, and said first cavity in said open position, said fluid passage communicating with said inlet, said first cavity and said second cavity in said closed position, and in said closed position said valve shuttle preventing communication between said inlet and said outlet, a volume of said second cavity being variable and defined by said valve cavity, a first position of said valve shuttle, and a second position of a shuttle piston slidably mounted about said valve shuttle within said second cavity, and said shuttle piston dividing said second cavity into an outlet cavity in communication with said outlet and a bias cavity having a source of a bias force.
