Positioning element for adjusting the operating width of a metering gap

摘要

The invention relates to a positioning element for adjusting the operating width of a metering gap ( 34 ) in a device ( 11 ) for applying flowable medium. Said positioning element comprises a cylindrical hollow member ( 58 ) that is closed at an end located on the driven side. At least one continuous bore ( 59 ) that forms a passage ( 61 ) between the at least one distribution channel ( 31 ) and the metering gap ( 34 ) is provided inside the cylindrical hollow member ( 58 ) while at least one sleeve section ( 54 ) which is embodied as a sealing and gliding element and surrounds the at least one continuous bore ( 59 ) or a group of continuous bores ( 59 ) is mounted on said cylindrical hollow member ( 58 ).
