Zusammenfassung:	Apparatuses and methods for pressure regulating check valve assemblies are described. In an example, the check valve assembly comprises a housing defining a fluid passage having a fluid inlet side and a fluid outlet side. A first check valve positioned within the fluid passage oriented to restrict fluid flow from the fluid inlet side and a second check valve positioned within the fluid passage oriented to restrict fluid flow from the fluid outlet side. A flow dampener is positioned within the fluid passage and between the first and second check valves.
