Command and control assembly for inflating and deflating a hydrostatic balancing jacket

A command and control assembly for inflating and deflating a hydrostatic balancing jacket, comprising:

• a primary supply duct configured to be connected to an end of an air chamber of the hydrostatic balancing jacket and having, at an opposite end, a hand piece provided with a mouthpiece;
• a connection socket provided on said hand piece, the connection socket being in fluid communication with a secondary supply duct configured to be connected to a compressed air tank;
• a pneumatic actuation duct that actuates a discharge valve of said hydrostatic balancing jacket and that is in fluid communication with said secondary supply duct;
• and
• a first control system of a delivery from said secondary duct, a second control system of a delivery to said pneumatic actuation duct, and a third control system of a delivery from said mouthpiece, which are arranged on said hand piece,
• wherein said hand piece is provided with an axial duct communicating at one end with said primary supply duct and, at an opposite end, with said mouthpiece,
• wherein said first control system and said second control system comprise two valves having seats that are shaped radially with respect to said hand piece and juxtaposed to one another, and in fluid communication with one another by way of a duct obtained in said hand piece and coaxial to the connection socket of the secondary supply duct and in fluid communication therewith,
• wherein said two valves are operated alternatively by a unique actuation organ,
• wherein each of the two valves comprises an actuation button, and
• wherein the buttons of the two valves are placed in proximity of each other but at a distance,
• further comprising a rocker lever disposed to oscillate around an intermediate axis perpendicular to a longitudinal extension of the rocker lever, said rocker lever having two opposite ends on opposite sides of the intermediate axis, the two opposite ends of the rocker lever being positioned to be each in contact with one of the actuation buttons, such that, by pressing on one of the two opposite ends of the rocker lever, one of the actuation buttons is operated so as to operate one of the two valves, another one of the actuation buttons remaining inactive or at rest in a position that does not operate another one of the two valves.
