Patent ID: 8568130

Claim:
A casting machine for casting a flowable mass, comprising: a mass container for receiving the flowable mass; at least one valve which is fluidically connected to the interior space of the mass container, the valve being in an open state in the presence of a pressure gradient along the flowing-through direction of said valve and in a closed state in the absence of this pressure gradient along the flowing-through direction of said valve; and a pressure generating means for generating a pressure gradient along the flowing-through direction of the valve; wherein the valve has a valve body with a valve opening and at least one valve flap assigned to the valve opening, which flap is articulated on the valve body and is subjected to an elastic prestressing which presses the valve flap against the valve opening and seals it; the pressure generating means is a metering chamber with variable chamber volume and with at least one metering chamber outlet valve and one metering chamber inlet valve, the metering chamber inlet valve being arranged in the fluidic connection between the mass container volume and the metering chamber volume; and a base of the mass container contains a multiplicity of holes, each of which opening out into one of upper valve channels.
