摘要： A paint circulating system back pressure regulator (50) comprises a flow passage (57) for paint, at least part of which is disposed between a fixed structure (56) and a moveable surface which is moveable to vary the width of the flow passage (57) so as to regulate a pressure of paint upstream of the regulator (50). The regulator (50) is also provided with a chamber having an opening for communicating with a supply of a pressurised fluid for controlling operation of the regulator (50).
