    摘要: An apparatus is disclosed for an improved one-way valve comprising a base for mounting in a chamber with a valve surface engaging with a sealing surface to close an input aperture of the chamber. A flexible web is interposed between the base and the valve surface for resiliently biasing the valve surface into engagement with the sealing surface thereby closing the input aperture. When a fluid pressure from the input aperture exceeds the resilient bias of the flexible web, the valve surface is displaced from the sealing surface for opening the input aperture to permit the flow of the liquid from the input aperture through the chamber into an output aperture. Upon a sufficient fluid pressure within the chamber, the valve surface engages with the sealing surface for closing the input aperture to inhibit the flow of fluid from the chamber into the input aperture.

    摘要: A humidifier having an outer housing with a top opening covered with a removable top member. A power chassis and a rotatable drum having a web of water absorbent material about its circumference are mounted within the housing and are each removable through the top opening. A removable water container is located within the housing below the drum. The container is readily cleaned or replaced by lifting it out of the housing through the top opening.
