摘要

#CMT# #/CMT# The ink cartridge (10) has housing (11) that limits an ink chambers (14,15). A connection (21) is provided at housing lower side (25) for establishing a fluid connection between the ink chambers. A power supply connection is formed at ink jet printer. The connector is arranged at a gravity valve (26) that blocks the ink supply through the connector upto a predetermined low pressure threshold value and releases the ink supply when the value exceeds the predetermined threshold value. #CMT#USE : #/CMT# Ink cartridge for an ink jet printer. #CMT#ADVANTAGE : #/CMT# The connector is arranged at a gravity valve that blocks the ink supply through the connector upto a predetermined low pressure threshold value and releases the ink supply when the value exceeds the predetermined threshold value, and hence provides a larger ink storage volume, high functional reliability and simple assembly of ink cartridge. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of an ink cartridge. 10 : Ink cartridge 11 : Housing 14,15 : Ink chambers 21 : Connector 25 : Housing lower side 26 : Gravity valve.
