A novel enhanced flow metering device is disclosed, as well as related methods, that safely controls and meters the flow of a flow material. A pump fills a flow metering device with a flow material, which then dispenses the flow material to a target. The flow material charges the device by moving into at least one chamber when an actuation shaft is in a charging position. Flow materials are dispensed from the chambers of the flow metering device when the actuation shaft is moved into at least one dispensing positions.
1. A flow metering device comprising: a housing including a cavity;an input conduit in fluid communication with the cavity;an output conduit in fluid communication with the cavity;a chamber which is in fluid communication with the cavity and which includes a compressible member comprising an elastomeric membrane configured to store energy; andan actuation shaft disposed in the cavity,the actuation shaft including at least one moveable seal defining at least one flow space within the cavity and configured such that when the actuation shaft is disposed in ...
