A method of and means for anti-contamination flow control in liquids in a system using a motor unit (1) adapted to be driven by a pressure liquid having its drive coupled to drive a pump unit (6) adapted to pump liquid under pressure to a consumer device (9), in which the liquid is discharged from the motor unit (1) through an air gap (4), and collected from the air gap (4) by the pump unit (6) whereby to continue flow of pressure liquid beyond the air gap (4) to the consumer device (9). |
