SWITCHOVER DEVICE FOR A THICK MATTER PUMP

摘要

A switch-over apparatus for a thick-matter pump includes a housing that forms a pre-fill vessel, which has first and second inlet/outlet openings and an outlet opening positioned on opposite sides of the housing. The apparatus further includes a pivot body positioned within the housing and that forms a duct. The duct includes a duct inlet configured to pivot between the first and second inlet/outlet openings and includes a duct outlet configured to align with outlet opening. The pivot body forms at least one seal chamber adjacent the duct inlet or duct outlet. The apparatus further includes an elastic seal positioned within the seal chamber and includes a support strip positioned within the seal chamber between the elastic seal and the pivot body. The seal strip forms first and second oblique-cut ends.
