Constructive disposition introduced in indeflator equipment applied in coronary angioplasty intervention represented by an evolutionary solution translated by improvements of construction nature in the locking/unlocking system of the embolus, providing a better control over the injection or removal of liquids and/or fluids in a balloon catheter, being such locking/unlocking system (A) presents a simple construction concept, with bigger reliability and durability, making easy its assembling, with small quantity of pieces, minimizing the possibility of non-conform mechanical performance, and additionally providing easy handling by nurses and/or auxiliary people, being that the operation to inflate or to empty the balloon catheter with liquid or fluid is made possible by the embolus (B) movement over the syringe (D), through the application of a force to inflate (Fi) or to empty (Fe) in the hold element (C), through an embolus rotation, since to inflate the balloon the system must be locked, where to that the locking/unlocking system ( 1 ) now claimed presents a mechanism where the multiplicity of teeth of the inferior part ( 5 b) of the crog rail component ( 5 ) acts directly over the thread region (B 1 ) of the embolus (B), being the maintenance of this position made possible by a totally distended helicoidal spring ( 6 ) when in the locking position.
