摘要:
An injection hole and a suction hole are formed in a handpiece (1), and a liquid supply source (2) is connected to the injection hole via a supply line (3). The supply line (3) includes an elastically deformable tube (12) disposed at the midway. Liquid within the liquid supply source is supplied by pressure to the injection hole by means of an external pump such as a roller pump acting to the pump tube from the outside.
摘要:
An energy-dissipating receptacle is disclosed for use with fluid jet cutting systems. The receptacle (10) contains a suspensoid where solid particles circulate within the cavity to at least substantially dissipate the kinetic energy of the fluid jet, together with means (20) for automatically maintaining an effective suspensoid in the cavity as the suspensoid volume is decreased by the wearing action of the fluid jet impingement. The effective volume of the suspensoid is preferably maintained by means of a filler tube (20) having a discharge end (20a) positioned within the receptacle. By including means for maintaining an effective volume of the suspensoid during the cutting process, the receptacle may be fabricated with compact dimensions for enhanced manoeuverability when coupled to a fluid jet nozzle for coordinated movement therewith.
