Cleaning equipment projecting low pressure detergent foam - has compressor turbine connected by immersion tube to closed vessel

摘要

The cleaning equipment produces and projects detergent foam at low pressure, avoiding the need for pressure gauges, safety valves etc. It comprises a turbine-type compressor (1) and a sealed vessel (2) producing the foam and equpped with a projection nozzle (4). The compressor can be connected to the vessel via a large-diameter immersion tube (3), with a spherical float (12) at the bottom of the latter forming a non-return valve. The float is guided by bars against the seat formed at the tube end, and works in a cage with perforated walls immersed in the detergent.
