Second-stage diving regulator

Abstract

A second stage diving regulator with separated stages that allows changing a position of connection of a LP hose for low pressure supplied from a first stage of the regulator, characterized in that around connected bodies there is a rotating ring with a valve seat and a valve terminated with a thread to which a low pressure LP coming from the first stage of the machine is connected horizontally. The rotation of the rotary ring is ensured at least in the range of 180 degrees from the starting position, through all the intermediate angles downwards towards the cylinder, up to a horizontal position opposite to the starting position, the side of the body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(15) The second stage of the breathing regulator for scuba diving includes the front body (1), rear body (2) and swivel ring (3) allowing free rotation by at least 180 degrees with respect to both body parts (1, 2) of the valve (4) on which the LP hose for low pressure from the first stage of the breathing regulator is mounted. Swiveling of the ring (3) with the valve (4) can be started from the position, in which the LP hose is connected on the left side of the body (1, 2) and a diver, through all in-between angles downwards, until the position, in which the LP hose is connected on the right side of the body (1, 2) and a diver.

(16) Cylindrical front part of the regulator consists of the front body (1) and the inflator button. The inflator button consists of an elastic inhaling membrane (5), fixed permanently to a pressure element (6) securing the membrane at the point of mating with the valve lever (7), perforated membrane cover (8), elastic element of the inflator button (9) and the nut securing all elements (10) tightened to the front body (1). The front body (1) has grooves (11) for the gasket (12) and guide (13) of the swivel ring (3). In the embodiment of the solution, the swiveling ring (3) rotates by sliding movement in the guides (13). Appropriate profiling (14) of the front body (1) allows 180-degree rotation of the valve (4).

(17) The cylindrical rear part of the regulator consists of the rear body (2), membrane of the exhaust valve (15), mouthpiece (16) and exhaust tee (17). The rear body (2) has grooves (11) for the gasket (12) and guide (13) of the swivel ring (3). Appropriate profiling (18) of the rear body (2) allows 180-degree rotation of the valve (4).

(18) On the swivel ring (3) there is a valve seat (19). Swiveling through all in-between angles downwards to the tank is much more functional, as in case of rotation upwards through the upper half of the circumference, the LP hose will not be in the diver's field of view and obstruct the view.

(19) The valve (4) with the lever (7) is mounted to the ring (3) with the nut (21), has grooves for the gasket preventing from body leaks and is ended with thread (24) allowing connection of the LP hose for low pressure from the first stage of the breathing regulator. Length of the valve (4) and shape and construction of the lever (7) allow operation in any possible position of the swivel ring (3)—from 0 degrees to 180 degrees.

(20) The exhaust valve with the exhaust valve membrane (15) together with the exhaust tee (17), regardless of the position of the ring (3) with the mounted valve (4), is always located in the bottom position thanks to which the exhaled bubbles of air are outside the diver's field of view.

(21) The used locking button (20) allows blocking of the rotation of the ring (3) with the mounted valve (4) in five positions every 45 degrees allowing full 180-degree rotation.

(22) Change of direction in which the LP low pressure hose is routed to the first stage of the regulator does not require rearrangement of the whole valve (3) or using any tools.

(23) In a simplified, two-element construction of the second stage of the breathing regulator for scuba divers, the front body (1) and swivel ring (2) constitute a single element—the front part of the body with the ring (23).

(24) In the simplified two-element construction of the second-stage breathing regulator for scuba divers, the rear part of the body (2), with the mouthpiece (16), exhaust valve (15) and exhaust tee (17), remains fixed with relation to the diver, while the entire front part of the body, with the ring (23) and valve seat (19) and the inflator button, turns by 180 degrees according to the same principle as in the three-element variant. A guide of the ring (13) is on the entire internal circumference of the front body with the ring (23) and constitutes an element that connects 2 bodies. The inflator button consists of the elastic inhaling membrane (5), fixed permanently to a pressure element (6) securing the membrane in the point of mating with the valve lever (7), perforated membrane cover (8), elastic element of the inflator button (9) and the nut securing all elements (10) tightened to the front body with the ring (23).

(25) Two parts of the body, the front body with the ring (23) and the rear body (2) are clamped with the guide of the ring (13) located on the whole circumference of the front body with the ring (23) moving in the groove of the ring (11) of the rear body (2). Tightness of the construction is ensured by using of the gasket (12) placed in the groove (11) of the rear body (2).

(26) The exhaust valve (15) with the exhaust tee (17), regardless of the position of the ring (23) with the mounted valve (4), is always located in the bottom position thanks to which the exhaled bubbles of air are outside the diver's field of view.

(27) The used locking button (20) allows blocking of the rotation of the ring (23) with the mounted valve (4) in five positions every 45 degrees allowing a full 180-degree rotation.

(28) Change of direction in which the LP low pressure hose is routed to the first stage of the regulator does not require rearrangement of the entire valve (3) and using any tools.
