摘要： An abrasive waterjet apparatus comprising a water jet fluid flow circuit, a positive displacement pump connected to the water jet fluid flow circuit, a pressure fluctuation equalising device (24) for said circuit, and an abrasive cutting nozzle assembly. The pressure fluctuation equalising device (24) comprises a high pressure chamber (27') connected to the waterjet fluid flow circuit, a low pressure chamber (29), and a moveable pressure equalising member (20, 21) that separates said chambers. In order to equalise pressure fluctuations in the waterjet fluid flow circuit, the moveable pressure equalising member (20, 21) is arranged to alter the volume of the high pressure chamber (27' ).
