Abstract
A one-way valve is provided for permitting fluid in one direction through the valve and preventing fluid flow in an opposite direction. The valve includes a plastic valve body having inwardly extending spokes for supporting a central hub member. The hub member supports an umbrella valve regulator member formed of a resilient material. A cap member is provided for attachment to the valve body wherein the cap member extends over and surrounds the resilient umbrella valve member. The cap member includes radially extending passages whereby fluid flowing into a first end of the valve may flow through the spoke portions to open the umbrella valve and pass out of the valve through the radially extending passages.
