Abstract
A dispenser for granulated chemicals consists of a flow passage in communication with a venting chamber and a mixing chamber along the flow passage with the chambers connected together and the mixing chamber connected to the outlet of a measuring container having an inlet for connection to a supply of granulated chemical. The mixing chamber includes valves ganged together to cause simultaneous closing of the inlet and opening of the outlet of the container on flow through the conduit and cessation of flow, respectively. Flow through the chambers is induced by formation of a low pressure zone at the outlet form the mixing chamber into the conduit.
