Patent number: 12326130Abstract: A fuel injector for liquefied gaseous fuel includes a housing defining a fuel path from an inlet end to an outlet end. A nozzle is disposed at the outlet end of the housing. The nozzle includes an orifice for delivering liquid fuel from the fuel injector and forms a valve seat. A valve assembly is disposed in the housing and is configured to control flow of fuel through the orifice. The valve assembly includes a reciprocating valve body that is movable within the housing between a closed position and an open position. A valve seal is held by the valve body and is formed of an elastomeric material. The valve seal includes a flat sealing surface that faces the nozzle and is configured to contact the valve seat so as to inhibit flow of fuel through the orifice.Type: GrantFiled: January 24, 2023Date of Patent: June 10, 2025Assignee: Power Solutions International, Inc.Inventors: Constantine Xykis, Mark Damico, Andy Suhy, Matthew Marek, Rahul Mangalore, Brian White, Grant Stockton, Arkadiusz Gazdowicz, Greg Wanek
