ABSTRACT:
A method of manufacturing a valve unit is disclosed that includes providing a plurality of injection molding dies that define a cavity corresponding in shape to the valve unit. The valve unit includes a housing and a valve, and the housing defines a fluid flow path with an axis having an upstream direction and a downstream direction corresponding to a predetermined direction of fluid flow in the fluid flow path. The valve is cantilevered and includes a valve body having a coupled end rotationally coupled to the housing and a free end, and the valve body rotates about the coupled end to thereby change flow through the fluid flow path. The method also includes simultaneously molding the housing and the valve within the cavity such that the valve body is formed with the free end extending away from the downstream direction of the axis of the fluid flow path.
