Abstract (en)
[origin: EP0315750A1] The pump for viscous material comprises two alternately working displacement cylinders 22', 22'' opening out via end face apertures into a material feeding vessel 10, a pipe switch gate 12, which is arranged inside the material feeding vessel 10, being alternately connectable on the inlet side to the apertures of the displacement cylinder and freeing the respective other aperture, and on the outlet side connected to a delivery line 40, together with a shut-off device 32 arranged behind the pipe switch gate 12 in the direction of conveying. The shut-off device 32 is arranged in a housing 34 which is connected to the material feeding vessel 10 for the purpose of recycling material via a through-aperture 60 in the partition wall 16. The shut-off device 32 is formed by a pipe section 42 arranged inside the housing 34, connectable to the wall through-holes 30, 36 and displacable or swivellable in relation to at least one of the wall through-holes 30. <IMAGE>
