ABSTRACT:
In a spray element for a spray head for spraying the molds of pressure casting machines, a control piston for the release of the parting agent supply is disposed beside the spray nozzle and a connecting passage opens in a chamber of the housing in which one end of the control piston is sealingly guided, while its second end lies with a sealing ring before a chamber fed with parting agent. In the case of the application of control air the sealing ring is shifted out of its cylindrical section26into the chamber, so that the feed of parting agent to the spray nozzle is released. If the control air is shut off, then the sealing ring closes the delivery of the parting agent, and the second, larger end of the control piston exercises upon its return movement a reverse suction effect on the connecting passage. Any after-dripping of parting agent is securely prevented.
