摘要

A suction installation without any float is for high pressure cleaners. It has self-actuated pipe system ventilation and return flow protection. The suction installation includes a distribution block (10) consisting of a pipe with at least two sockets, i.e. a suction socket for water pressure in (6) and a chemicals socket (7). There is an inverted U bend with a screwed on double wall valve (8). There is an oscillation damper (11). Leading from the distribution block there is at least one suction socket connected thrugh a valve and a non-return valve to a suction valve of the pump to be used as a chemical measuring out socket.
