ABSTRACT:
The device consists in a variable restriction installed in conjunction with a chip blower, located between the warm water inlet and the return line connecting the relative handpiece to the main waste outlet, which is made to open continuously or intermittently, at least while the apparatus is in operation, so as to allow a moderate trickle of water through to the waste outlet and ensure that no stagnation occurs; the particular method of installing the restriction also permits of keeping the handpiece at a temperature near to that of the water supplied through the inlet, even when the blower is not actually in use.
