air flow under pressure to be used to power drill 24 via line 25 and to pump cleaning fluid received into manifold section 17a via flowline 26 that passes through valve 27 the manifold section 17a thus can provide fluid flow between the flowline 26 and the flowline 19 with pressure being added to that flowline at manifold 17a as supplied to the airflow leaves manifold section 17a via flowline 29 and is transmitted via line 29 to eductor 30 the eductor 30 includes an inlet 31 an outlet 32 and a cleaning fluid influent 33 the influent 33 receives dirty cleaning fluid via line 34 which exits the outlet 35 of rotor housing 20 the dirty cleaning fluid contained in line 34 will include the cleaning fluid which is a commercially available solvent as well as dirt rust scale hydrocarbons and or drilling mud compressed air enters eductor at inlet 31 via flowline 29 from manifold section 17a compressed air 31 passes through the eductor 30 fig2 which includes a central longitudinally extending open ended bore 30a between end portions 31 and 32 which communicates respectively with influent flowline 29 and effluent flowline 32 intersecting the central longitudinal bore 30a at a lateral direction with resect thereto is a lateral bore 30b that communicates with influent liine 33 so that fast.
