    Abstract: A check-type valve assembly in which an annular channel is formed in a valve body. A port is formed in the inner surface of the channel and is closed by an elastic band which is positioned under tension in the channel so as to bear tightly against the inner surface thereof. The elastic band functions as a valve element for controlling the flow of fluid through passages communicating with said port and the annular channel.
