device to foster pastenartiger masses.

摘要

In a vane-cell pump for conveying pasty masses, for example sausage meat for metering or metered filling of sausage casings, flow of the mass into the pump chamber (2) is conventionally achieved by a stuffing device in the feed hopper and the action of a vacuum applied to the vane-cell pump. To improve the degree of filling and thus the metering accuracy, the pump chamber is provided with a hollow groove (5) in the transitional region between the inner wall of the cylindrical part (4) of the pot-shaped pump housing and the base part (3), containing the pump rotor bearing, of the pump housing. …IMAGE…
