Abstract

An applicator unit (100) is disclosed for applying glue or another fluid medium on a substrate (36). The housing (10) is subdivided into a glue guiding part (2) and into a driving part (1) that receives a piezoelectric element (20). A valve member (30) arranged in the glue guiding part (2) may be moved in the direction of an axis (11) and forms a glue discharge valve (40). The glue discharge valve (40) is normally closed by a stack of disk springs (25) that stresses the valve member (30). When a voltage, resulting in an expansion, is applied to the piezoelectric element (20), said element moves the valve member (30) against the force of the stack of disk springs (25) and opens the glue discharge valve (40). In order to avoid heat transmission from the hot glue guiding part (2) to the driving part that contains the piezoelectric element (20), the parts (1, 2) are mutually separated by a heat insulating zone (3).
