Abstract

PURPOSE:To control the ink pressure in the accumulator highly accurately by providing a bellows or a diaphragm whose cross sectional area is smaller than another diaphragm in the wall of an upper chamber which is separated by the diaphragm in the accumulator, and detecting the displacement of the bellows or the diaphragm. CONSTITUTION:The space in the accumulator 20 is separated by the diaphragm 22 into the upper and lower chambers. An inlet port 25 and an outlet port 26 for the ink are provided in the lower chamber 23. An opening 30 is provided in the ceiling wall of the upper chamber 24. The upper surface thereof is closed by the diaphragm or the bellows 31, and liquid 32 fills up the inside. The cross sectional area of said bellows 31 is considerably smaller than the area of the diaphragm 22 (e.g. about 1/20). The top surface of said bellows 31 is pushed by a weak spring 33. A pressur detecting pin 28 is provided on the top of the bellows 31. The displacement of said pin 28 is detected, thereby the ink pressure supplied to the inlet port 25 of the lower chamber 23 is controlled.
