Abstract
Guide vane check valve assemblies and poppets for guide vane check valve assemblies are disclosed. A guide vane poppet includes an elongate central core configured to form a fluid seal with a valve body of the check valve assembly. The guide vane poppet additionally includes an elongate outer skirt and at least one guide vane radially extending between the elongate central core and the elongate outer skirt. A check valve assembly includes a valve body with a central cavity, an inlet to the central cavity, an outlet from the central cavity, and a spring seat, and further includes a spring and a poppet. The spring is oriented to press against the poppet and to urge a poppet-side sealing surface of the poppet into sealing engagement with a body-side sealing surface of the valve body.
