ABSTRACT:
A wax cylinder for a wax spraying machine is disclosed. The wax cylinder includes a housing, an ejection cylinder having a chamber mounted in the housing. An elongated piston is slidably mounted in the chamber and includes a pressure face for pressurizing and urging wax in the chamber out through an ejection opening. The chamber is maintained in constant fluid communication with a feed line for feeding wax into the chamber throughout the stroke of the piston. A check valve is utilized to prevent back flow of wax through the feed line. Air is prevented from flowing into the chamber during the return stroke of the piston.
