The present invention concerns a re-configurable pressure regulator (10) for breathing apparatus. The regulator comprises a valve housing (14) having connection means (36,52) at first and second ends thereof for connection, in use, at one of the ends to a pressurised source (90,92) of breathable gas and at the other end to a removable blanking plug (42), wherein in a first configuration of the regulator the first end is closed by a removable blanking plug and in a second configuration the second end is closed by the blanking plug, with the other end being open and connectable to said breathable source of gases. The regulator further comprising a diaphragm case (12) and a diaphragm (18) located therein dividing the interior of the case to provide a first chamber (16) having an inlet/outlet for communicating breathable gases to and from a user. The first chamber accommodates at least part of the valve housing. The interior of the valve housing defines a second chamber in communication with the first chamber and accommodates a dual acting valve (70,72), which in the first configuration of the regulator is operable to open and close a valve opening at the second end of the valve housing for communication with the source of breathable gases, and in the second configuration is operable to open and close a valve opening at the first end of said valve housing for communication with the source. Valve control means (22) are provided for regulating movement of the valve in accordance with the deflection of the diaphragm in the diaphragm case.
A re-configurable pressure regulator for breathing apparatus, said regulator comprising a valve housing having connection means at first and second ends thereof for connection, in use, at one of said ends to a pressurised source of breathable gas and at the other of said ends to a removable blanking plug, wherein in a first configuration the said first end is closed by a removable blanking plug and in a second configuration the second end is closed by said blanking plug with the other end being open and connectable to said breathable source of gases.
A pressure regulator as claimed in any preceding claim wherein said valve control means comprises a lever which moves in accordance with the position of the diaphragm.
A pressure regulator as claimed in any preceding claim wherein the said diaphragm case further comprises an exhaust valve for exhausting exhaled gases from said first chamber.
A method of reconfiguring a pressure regulator for use with different breathing apparatus, said regulator comprising a diaphragm case and a diagram located therein dividing the interior of the said case to provide a first chamber having an inlet/outlet for communicating breathable gases to and from a user, the said first chamber accommodating at least part of a valve housing having connection means at first and second ends thereof for connection, in use, at one of said ends to a pressurised source of breathable gas and at the other of said ends to a removable blanking plug, wherein in a first configuration the said first end is closed by a removable blanking plug and in a second configuration the second end is closed by said bluing plug with the other end being connectable to said breathable source of gases, the interior of the valve housing defining a second chamber in communication with the said fix chamber and accommodating a dual acting valve means which in said first configuration is operable to open and close a valve opening at the said second end of said valve housing for communication with said source of breathable gases and in said second configuration is operable to open and close a valve opening at the said first end of said valve housing for communication with said source, and valve control means for regulating movement of the said valve means in accordance with the deflection of the said diaphragm in the said diaphragm case;
A pressure regulator substantially as hereinbefore described and with reference to the accompanying drawings.
A method of reconfiguring a pressure regulator substantially as hereinbefore described and with reference to the accompanying drawings.
