Abstract

A variable flow restrictor (6) is installed in conjunction with a chip blower (13), located between a warm water inlet (2), and a return line (18), connecting the relevant handpiece to the main waste outlet (7). The restrictor may be operated manually, or preferably automatically, and may open either continuously, or intermittently to allow a modurate trickle of water to waste.
