Abstract
A system for providing a high pressure pulsating flow of cutting fluid includes a piston pump having a piston cylinder for pumping the cutting fluid and an air cylinder for reciprocatingly actuating the piston cylinder. An air-operated direction change-over valve controls supplying of air to one end of the air cylinder or the other from a compressed air source. A pulse frequency setting unit, including a fluidic NOT device, controls the position of the change-over valve pneumatically thereby determining the frequency of reciprocation of the air cylinder and thereby the frequency of pulsations in flow of the cutting fluid.
