APPLICATION HEAD FOR DISPENSING A FREE-FLOWING MEDIUM AND APPLICATION DEVICE FOR DISPENSING A FREE-FLOWING MEDIUM

摘要

The invention relates to an application head (15) for dispensing a free-flowing medium. The application head (15) comprises an injection chamber (10) inside the application head (15) and an injection needle (11) movably mounted inside the injection chamber (10). An opening movement (P) of the injection needle (11) opens an outlet (12). A supply channel (13) and a supply line are also provided in order to introduce the free-flowing medium into the injection chamber (10). A drive (20) generates the opening movement (P) of the injection needle (11). The application head (15) also comprises a lever arm (30), the first end (31) of said arm being movably fixed to a rear end (14) of the injection needle (11) and the second end (32) thereof being connected to the drive. A membrane suspension (33) comprising a membrane (34) is provided, and the lever arm (30) extends through the membrane (34) of the membrane suspension (33). The membrane suspension (33) is used to movably connect the lever arm (30) to the application head (15), and as a seal to prevent the free-flowing medium from leaking out.
