Abstract

dispositivo acionador. a presente invenção ser refere a um dispositivo que pode ser utilizado em conexão com poços de petróleo e/ou gás, com a finalidade de aumentar a produção do poço. o dispositivo compreende uma estrutura externa, em cuja estrutura externa um primeiro e um segundo dispositivos de fole influenciados por pressão são montados, onde o primeiro e segundo dispositivos de fole influenciados por pressão são dispostos em conexão de fluido entre si, através de um dispositivo de suporte. na extremidade oposta à conexão com o dispositivo de suporte, o segundo dispositivo de fole influenciado por pressão é conectado a uma luva móvel. o dispositivo compreende ainda um mecanismo de fechamento articulável ou giratório para o mesmo, onde o mecanismo de fechamento é conectado à luva móvel.trigger device. The present invention relates to a device that can be used in connection with oil and / or gas wells for the purpose of increasing well production. the device comprises an outer frame, in which outer frame a first and second pressure-influenced bellows devices are mounted, wherein the first and second pressure-influenced bellows devices are disposed in fluid connection with each other by means of a pressure device. Support. at the opposite end to the connection with the support device, the second pressure-influenced bellows device is connected to a movable sleeve. The device further comprises a pivoting or swivel closure mechanism therein, wherein the closure mechanism is connected to the movable sleeve.
