Embodiment Construction

[0024] Reference will now first be made to the attached image 3 , illustrating a preferred embodiment of the innovative valve arrangement and the innovative breathing regulator. It should be noted that references to directions in the description, such as up, down, etc., refer only to those directions as shown in the figures, and thus should not be taken as limiting the scope of the invention when interpreting the appended claims.

[0025] image 3 is the schematic diagram of the innovative valve arrangement. The valve arrangement comprises an inlet side 111 , an outlet side 112 , a diaphragm or diaphragm 116 , a diaphragm spring 117 and a stem 118 . These valve components are figure 1 The valve components shown correspond accordingly. The valve arrangement also includes a valve closure member in the form of a ball 114 which rests on an opening 115 a in the valve seat 115 . Unlike the valve seat used in the prior art valve technology described, the valve seat 115 can move...

Abstract

A valve device, particularly for a breathing regulator (100) for divers, comprising an inlet chamber (111) which can be connected to a source of gas under super-atmospheric pressure, and an outlet chamber (112) which is under a regulated pressure. A seating (115)-which is movable under the influence of the super-atmospheric pressure and the regulated pressure, seals between the inlet chamber and the outlet chamber and has a through-passing passageway (115a) that interconnects said chambers. Also included is a valve body (114) which is movably arranged in the seating such as to open and close the through-passing passageway in said seating. A servo element (116, 117, 118) exerts on the valve body a force that depends on the position of the movable seating, so that varying force-influence on the valve body from the super-atmospheric pressure will be compensated for by a corresponding varying force from the servo element. This results in an essentially constant valve characteristic, while providing a mechanically simple solution at the same time.

Description

technical field [0001] The present invention relates to balancing valve arrangements and more particularly to balancing valve arrangements for controlling the flow of pressurized breathing gas to a breathing regulator. The invention also relates to such a breathing regulator. Background technique [0002] Diving equipment comprises a so-called breathing regulator which is connected to one or more diving tanks or their technical equivalent and which is used to regulate the pressure of said tanks to a predetermined regulation pressure. For this purpose, the breathing regulator is provided with a valve arrangement. figure 1 A valve arrangement of this type constructed according to the prior art is schematically illustrated. As will be understood, the valve includes 入口 lower inlet side 11 and at the regulated pressure P 出口 12 under the outlet side. The conical valve body 14 is movably seated in the valve seat 15 . The outlet side 12 is defined by a flexible diaphragm or me...
