ABSTRACT:
A flow regulator has a pair of side walls extending generally parallel to one another, a bottom wall connecting the side walls to one another and defining an elongate channel for receiving a compressible tube, a roller rotatably and shiftably mounted to the side walls for rolling along the tube in the channel and compressing the tube against the bottom wall. The bottom wall is provided with a formation which varies from a first end of the channel towards an opposite, second end thereof, whereby compressive force applied to the tube via the roller is different at different longitudinal positions of the roller along the channel. A bracket is disposed about the side walls at one end of the channel. The bracket is in contact with outer surfaces of the side walls only in regions of the side walls spaced from the bottom wall.
