EDUCTOR

摘要

An eductor apparatus (1) having an air gap (2) and a venturi (3), a bypass channel (8) and a spray protection device (10) in the form of a deformable porous body to prevent splash back produced at the inlet to the venturi from escaping through the air gap (2). The spray protection device (10) may also function to absorb the energy of a misaligned water jet and provide an emergency flow path.
