Abstract: A static mixing element (10) for mixing free-flowing compounds such as multi-component injection mortar, includes a first shell part (11) and a second shell part (12) which can be placed against one another in an axial longitudinal direction (13) at their respective sealing edges (14, 15) and are connected to one another by a connection element (30). Flow-directing elements (20) are arranged in a flow-through chamber (16) that is defined between the two shell parts (11, 12) and which extends from an inlet opening (17) to an outlet opening (18). These flow-directing elements (20) are formed as vane elements (21, 22) which project out over the sealing edges (14, 15) of one of the shell parts (11, 12) and leave open a portion (35) of the flow-through chamber (16) at a sealing edge (14, 15) of another of the shell parts (11, 12).

Abstract: A quick-acting closure (1) for connecting a mixer tube (3) and a connecting part (2) of an extruder unit. The connecting part (2) has a connector (9) with a conical threaded base member, on which an external thread (12) is arranged. The mixer tube (3) has a conical threaded base member, on which an internal thread (19) is arranged. The internal thread (19) on the connector part (16) of the mixer tube (3) is a multi-path internal thread.
