OIL SUPPLY DEVICE, PRINTING MACHINE, OIL SUPPLY METHOD, AND COMPUTER PROGRAM FOR OIL SUPPLY

摘要

An object is to supply a fixed amount of oil determined in advance. In the present invention, a lubricating device that supplies oil to each sliding device of a printing machine includes a lubricating section and a metered valve. The lubricating section ejects oil in an oil reservoir section into a piping when lubrication is performed. The metered valve is configured to eject oil accumulated in an ejection side cylinder chamber from an ejection opening by oil pressure from the oil ejected into the piping. The oil ejected into the piping is accumulated in a supply side cylinder chamber. When a lubricating pump is stopped and depressurized, the oil accumulated in the supply side cylinder chamber moves to the ejection side cylinder chamber.
