Summary:A delivery device for a metal melt in an injection-moulding machine, for example a metal casting machine, has a storage container for the metal melt and a delivery channel in which the metal melt is fed to a mould cavity. In this case, provision is made for the delivery channel to comprise a cylindrical bore in which a piston is arranged in an axially adjustable manner. Provided for the metal melt is a collection chamber from which the metal melt is introduced into the mould cavity through a continuing line as a result of an axial displacement of the piston. Formed between the outer wall of the piston and the inner wall of the cylindrical bore is an annular space which is connected to the collecting chamber via at least one filling bore. At its end that opens into the collecting chamber, the filling bore is closable by means of a valve body which is connected to an adjustable valve rod which is arranged in a displaceable manner in an axial bore of the piston.
