Abstract: A pressure-reducing system for a breathing apparatus comprising: i) a supply conduit (2) for supplying a pressurised breathable gas; ii) a suction mouthpiece (3) for a user to breathe in the breathable gas; iii) a valve (4) operatively interposed between the supply conduit (2) and the suction mouthpiece (3), the valve (4) in turn comprising: -an inlet (41) for the breathable gas coming from the supply conduit (2); -an outlet (42) for the breathable gas directed to the suction mouthpiece; -a shutter (43) that is movable between a first and a second position in which it respectively permits or prevents the passage of the breathable gas from the inlet (41) to the outlet (42); -a pressure balancing chamber (44), said shutter (43) being interposed between the inlet (41) of the valve (4) and the balancing chamber (44); the shutter (43) defining a conduit (430) that places the inlet (41) of the valve (4) and the pressure balancing chamber (44) in fluid communication; iv) a movement system (5) for moving the pres

Abstract: A pressure reducing second stage for underwater use includes a case provided with a breathing gas inlet, with an inhalation/exhalation port and with an exhaled gas exhaust outlet with a non-return valve, the gas inhalation/exhalation port being connected to a mouthpiece tube, the breathing gas inlet in the case being connected to a breathing gas pressure reducing device provided with a hollow cylindrical element or pipe, which has a breathing gas inlet port communicating with a gas supply conduit through a valve which is interposed between the supply conduit and the mouthpiece tube, the case being provided with a pressure sensitive means device for controlling the opening/closure of the valve. The breathing gas inlet in the case is provided in its lower portion and the hollow cylindrical element is connected to the inlet on the case such that its axis is substantially vertical, when used in the upright position.

Abstract: A regulator assembly particularly for tanks for scuba divers, comprising a first pressure reduction stage, which can be connected to a tank of compressed air connected, by means of a hose, to a second pressure reduction stage associated with a front regulator. The assembly comprises, at the connection between the hose and the front regulator, a first L-shaped connector for arranging the hose laterally adjacent to the face of the user of the tank. The hose is arranged proximate to the upper region of a shoulder of the user with the tank arranged at the back of the user.

Abstract: An equipped balancing jacket comprising a stiff back housing (1), a first stage pressure (101) reducer connected to at least one compressed air tank, said first stage pressure reducer being in turn connected by means of a low pressure hose (LP) to a first distributor (3) (12), said first distributor being in turn connected by lines coming out from said first distributor with a plurality of outlets (13, 14) characterized in that the stiff back housing has a cavity, the internal surface of the cavity has a grooved guide (15) and the distributor (12) is engaged with this guide and in use moves trough it.

Abstract: A padding element for the dorsal side of a diver's bottle-supporting backpack. The padding element comprises a padded cushion capable of being fitted against the back part of the backpack and having at its lower edge a padded cushion part hinged to it and capable of being either folded upwards, in order to increase the total thickness, and hence the padding action of the cushion over the diver's sacrococcygeal region, or unfolded downwards to give the diver extended protection beyond the lower edge of the bottle or bottles attached to the backpack.

Abstract: Inflating device for balancing jackets for diving activities equipped with at least partially horseshoe-shaped inflatable chamber comprising two descending branches communicating one with the other on their upper portion, characterized in that on the connection of the inflating valve ending on the base of one of the branches of the inflatable chamber of the jacket is arranged a tubular connection with a substantially T-shaped branch comprising a first tube portion ending directly on the basis of said first chamber, and a second tube portion covering the whole ascending arch of said first chamber and at least part of the descending arch of the second chamber of the jacket until it ends on the base of the second inflatable chamber of said jacket.

Abstract: Buoyancy control jacket for underwater activity provided with an inflatable bag having two arms in the shape of a U or a horseshoe made up of an outer bag and an inner air tube. In the vicinity of the ends of the two arms of the outer bag of the jacket there are two relatively short openings that extend approximately along the directrices of the said outer bag, each opening having a robust zip giving access to the interior of the said jacket. Advantageously, the said openings extend along a region located between the ends and the centre line of the lateral arms of the jacket, on the rear part of the jacket.

Abstract: Balancing jacket for diving activities equipped with integrated packing system for its transport. Onto two areas symmetrically opposed with respect to the middle of the back portion of the jacket cooperating connecting means are applied, which connect said portions in an easily engageable and releasable way. The invention also relates to a method for packing a balancing jacket for diving activities by means of an integrated wrapping system, comprising the following steps: (a) tidily folding the components of the jacket on the front side; (b) assembling said elements as a package by pulling said complementary connecting means on the back portion of the jacket, and (c) firmly connecting said complementary connecting means, thus forming a compact package or assembly.

Abstract: An equipped balancing jacket includes a stiff back containing a first stage reducer connected by lines to a high and low pressure distributor connected to various equipment. The jacket further includes pneumatic exhaust valves, a manual emergency control and a mouth inflation devcie.

Abstract: A hydrostatic balancing jacket includes a dorsal element ending into two shoulder strips and two pectoral-abdominal strips. The dorsal element is equipped, on its outer side, with two wing-shaped strips. The wing-shaped strips are connected to the dorsal element along one of their rims. The wing-shaped strips are symmetrically located with respect to the longitudinal axis of the element and are inflatable.
