- the housing also contains a seat for two balls, in which these balls are freely movable.
- the sleeve also has a shape corresponding to the diameter of the balls. In the rest position, which corresponds to the filling position, pushes the emptying nozzle facing ball on the soft tube and closes it.
- the other ball does not affect the pipe cross-section, so that the pipe is filled up to the emptying nozzle facing ball with pressurized product. If the sleeve is moved in the direction of the nozzle, the other ball is pressed onto the tube and closes it against the reservoir, while the emptying nozzle facing ball finds space in the seat of the sleeve and the pipe cross-section releases. The product can escape from the emptying nozzle.

- On the bicycle chain-like coupling means 11 1 three pressure rollers 94, 96 and 98 are arranged in the illustrated example, advantageously uniformly spaced from each other.
- Each pressure roller 94, 96 and 98 is rotatably mounted about their longitudinal axis 95, 97 and 99 respectively. These longitudinal axes 95, 97 and 99 are advantageously perpendicular to that of the rotational axis. body 92 and / or 93 level.
- the rotary body 92 and / or 93 are coupled to a drive of the linear peristaltic pump 91.
- the bicycle chain-like coupling means 111 is also set in motion, so that the pressure rollers 94, 96 and 98 successively act on the elastic peristaltic hose 31 and elastic within
- Peristaltic pump tube 31 flowable mass or continuously convey the powder.
- the elastic hose pump hose 121 shown in FIGS. 12 to 14 for arrangement in a peristaltic pump 61 or 91 for conveying flowable masses and powder has a hose lumen 122 with an elliptical, almost lenticular cross-section.
- the peristaltic pump tube 121 has a constant cross-section of the tube lumen.
- This Schlauchpumpensch leuch 121 is formed such that it is interchangeable in a peristaltic pump 61 or 91 and / or a portioning unit 21 can be arranged.
- coupling sections 124 and 125 are injection-molded.
- spring elements 126 are provided for the peristaltic pump tube 121.
- the spring elements 126 are arranged in pairs and in each case opposite one another.
- the pairs of spring elements are arranged at a distance from one another along the longitudinal extension of the peristaltic pump tube 121, in this example in each case at the same distance.
- the spring elements 126 are integrally formed with the hose pump hose 121 and - in this example - made of the same material as the peristaltic pump hose 121.
- a fixing device 128 for the peristaltic pump hose 121 is provided, via which the peristaltic pump hose 121 can be fixed, if necessary, in a peristaltic pump 61 or 91 and / or a portioning unit 21.
- a holding device designed to be complementary to the fixing devices 128 is arranged in the peristaltic pump 61 or 91 and / or the portioning unit 21.
- the hose pump hose 131 shown in FIG. 15 likewise has a hose lumen 132 and spring elements 133 and 136 lying opposite one another.
- the spring element 136 is integrally formed with the peristaltic pump tube 131 and made of the same material as the peristaltic pump tube 131.
- the spring element 133 is designed as a separate element and made at least partially from a different material, such as the hose pump hose 131.
- a guide section 134 which can be brought into contact with the separate spring element 133 is provided in a corresponding region on the outside of the peristaltic pump tube 131. hen, so that the Sehlauchpumpenschiauch 131 is guided along its longitudinal extent on the separate spring element 133.
- the separate Federeiement 133 is provided, for example, in the Schiauchpumpe 61 or 91 and / or the Portioniermaschine 21, Aiternativ is the separate spring element 133 z.
