ABSTRACT:
A unidirectional fluid flow check valve assembly is ideally suited for controlling gaseous fuel flow to pre-combustion chambers of internal combustion engines. The unidirectional fluid flow check valve assembly has an orifice plate having a center orifice biased against a valve seat by a spring. The valve seat has a plurality of ports unaligned with the orifice. A valve plate is held in confrontational relationship with the orifice plate and has a center port aligned with the orifice. The valve plate is sized and positioned to allow the orifice plate to move between the valve plate and the valve seat. All of the valve components can be assembled within a receptacle end of a male inlet housing. The inlet housing can then be threaded into a female outlet housing, forming a valve chamber therebetween. The combination of elements provides a valve that is easy to assemble, does not need valve seals, and prevents the orifice plate from floating during low pressure situations.
