Abstract
A venturi type pumping device including a body having a tubular through bore between a bore inlet end and a bore outlet end, a restriction in the bore acting to produce a reduction in pressure downstream from the restriction, a delivery device for the delivery from a delivery outlet of a pressurized stream of liquid substantially axially aligned with the bore and upstream from the bore inlet end, a bore extension member which terminates upstream from and encloses the delivery outlet, and a mounting device provided on the body for sealing engagement of the bore extension member to the body.
