DISPENSING MODULE, APPLICATOR HEAD AND NOZZLE HOLDER FOR DISPENSING A FLUID, IN PARTICULAR HOT-MELT ADHESIVE

摘要

The invention relates to a dispensing module (1) for an applicator head for dispensing a fluid, in particular hot-melt adhesive, comprising a module housing (5), a valve body accommodated in the module housing (5), an adapter (7) through which the valve body extends, comprising a proximal end (49) and a distal end (41), the distal end (41) being connected by means of a screw connection (51) to the module housing (5), a nozzle holder (9) which is adapted to be inserted into a matching recess in a base member of the applicator head, and one or a plurality of sealing elements (57, 59, 61) for sealing the nozzle holder (9) and the base member against each other in a fluid-tight manner. According to the invention, it is proposed that the nozzle holder (9) comprises a cavity (69) through which the valve body extends, is connected by means of a screw connection (51) to the proximal end (49) of the adapter (7), comprises a valve seat (79) which is adapted to cooperate with a valve head (31) of the valve body, and comprises an elongate section (75) upstream from the valve seat (79), within which the cavity (69) is limited to a narrow gap (77).
