摘要： A sealing device for sealing off the intermediate space between a housing and a shaft which is mounted rotatably in the housing, which housing has a first plate-like body with a front side, a rear side and a first opening extending from the front side to the rear side and suitable for the leadthrough of the shaft, and has a line which runs in the body and which is suitable for conducting a liquid or gaseous medium. Here, the first body is suitable for being fastened sealingly to the housing such that the shaft which is rotatably mounted in the housing is led through the first opening. The line has a multiplicity of outlets which are connected to an inlet via at least one diversion and/or at least one divergence and which lead radially symmetrically into the first opening. The first opening is suitable for the introduction of first sealing such that the first sealing seals off an intermediate space between the shaft and the first body without blocking the outlets of the line.

摘要： A sealing device for sealing the intermediate space between a housing and a shaft rotatably mounted in the housing, having a first plate-shaped body with a front face, a rear face, and a first opening, which extends from the front face to the rear face and is suitable for feeding through the shaft, and having a cooling line, which runs in the body and is suitable for conducting a cooling medium. The first body is suitable for being tightly secured to the housing such that the shaft rotatably mounted in the housing is guided through the first opening. The first opening is suitable for introducing sealant such that the sealant seals an intermediate space between the shaft and the first body. The cooling line is guided around the first opening between a cooling line inlet and a cooling line outlet for the cooling medium such that heat produced from rotating the shaft can be dissipated by the cooling medium in a spatially homogenous manner.

摘要： An extruder screw for the plasticizing of at least one plastic material or a plastic material mixture, with a melting zone, a wave zone and a mixing zone arranged between the melting zone and the wave zone, wherein a conveying web extending in a helix-like manner along a screw longitudinal axis is formed in the melting zone and in the wave zone, wherein a conveying web of the melting zone terminates at an end of the melting zone facing the mixing zone, and a conveying web of the wave zone begins at an end facing the mixing zone. The application also relates to an extrusion device with this extruder screw, and a method for plasticizing at least one plastic material or a plastic material mixture.

摘要： An extruder screw for plasticizing at least one plastic or plastic mixture, including a melting zone, a shaft zone and a mixing zone arranged between the melting zone and the shaft zone, wherein a conveying flight is formed in the melting zone and in the shaft zone, which extends helically along a longitudinal axis of the screw, wherein a conveying flight of the melting zone ends at an end of the melting zone towards the mixing zone and a conveying flight of the shaft zone begins at an end towards the mixing zone. A flight depth of the melting zone continuously decreases along the longitudinal axis of the screw to the mixing zone. Further, an extrusion device having the extruder screw and to a method for plasticizing at least one plastic or plastic mixture.

摘要： A connection device for connecting an outlet opening of a downpipe to an upward-facing inlet opening of a container, comprising a body with a continuous opening from an upper side to an underside of the body, wherein the body is designed in such a way that it is suitable to before being connected by its upper side to the outlet opening of the downpipe via a flexible connection element, in particular via a compensator, in such a way that a connection is created between the outlet opening of the downpipe and the opening of the body. The connection device also comprises a coupling device which is attached to the underside of the body and which is suitable for creating a sealed connection between the opening of the body and the inlet opening of the container when the body rests on an upper side of the container.
