Abstract
The invention relates generally to a check valve and more particularly to a check valve for a fuel passage of a prechamber assembly of an internal combustion engine comprising a carrier member, a stop member, and a ring member. The ring member is resiliently disposed between the carrier and stop members. The ring member is movable between a first position blocking fluid communication between the carrier and stop members and a second position passing fluid between the carrier and stop members. The principal use is for applications that control fluid passing between components, such as prechamber assemblies in gaseous engines.
