Abstract
In order to prevent the contamination of particulates such as food material particulates, facilitate maintenance, and to enhance the process sealing accuracy, a flow path switchover device is presented. The device of the present invention has a tube assembly including first and second main tube members and a branch member. The first and second main tube members are interconnected via a first ring member. The first main tube member and the branch member are interconnected via a second ring member arranged at a preset angle with the first ring member. A metal changeover damper supported on a rotating shaft swings between the first and second ring members and accordingly blocks and seals either the connection between the first main tube member and the second main tube member or the connection between the first main tube member and the branch tube member, while allowing the other connection.
