A unit for transferring a charge of air under pressure from a reservoir or accumulator to a container of dispensable or flowable material of granular or like nature. The unit is in the form of a hollow body having at one end a flange for connection to the reservoir, at its other end an inlet for receiving air under pressure, at one side a flange for connection to the container and an interior piston-valve operative first to enable charging of the reservoir with a large volume of air under pressure and second to release the reservoir air rapidly into the container.
