ELECTRIC APPLICATION HEAD FOR DISPENSING A FREE-FLOWING MEDIUM, AND DEVICE COMPRISING SUCH AN ELECTRIC APPLICATION HEAD

摘要

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

主权项

1. An application head (15) for dispensing a free-flowing medium (M), the application head comprising:
a chamber (10) in the interior of the application head (15), a movable element (11), which is mounted so it is movable in the interior of the chamber (10), it releasing or closing an outlet opening (12) through a movement (P) of the nozzle needle (11), a supply channel (13), which is connected to the chamber (10) and is connectable with respect to flow to a supply line (16) to be able to introduce the free-flowing medium (M) into the chamber (10), a drive (20) for generating the opening movement (P) of the movable element (11), a lever arm (30), whose first external end (31) is fastened so it is movable on a rear end (14) of the movable element (11) and whose second external end (32) is connected to the drive (20),
a membrane suspension (33) having a membrane (34),the lever arm (30) extending through the membrane (34) of the membrane suspension (33),the membrane suspension (33) being used for the purpose of connecting the lever arm (30) to the application head (15) so it is movable, andthe membrane suspension (33) being used as a seal to prevent the free-flowing medium (M) from escaping from the chamber (10).
