Abstract
An hydraulic connection assembly for connecting one or more hydraulic lines may have a one-block body enclosing one or more hydraulic lines and at least one draining line connected to said hydraulic lines. The assembly may also have at least one coupling provided with an axially movable element adapted to actuate a sealing member to allow discharge of fluid pressure and relieve pressure from the tool lines before disconnecting or to facilitate maneuvering of connecting lines. The assembly also reduces the production costs and time, as well as the threes that the operator must apply when engaging pressurized lines.
