Abstract
A first stage pressure regulator for use with a high pressure source of breathable gas includes a housing and either a yoke arrangement for connection to the conventional U.S. high pressure gas source or a DIN connection for coupling to a European-type gas source. First and second presure-regulated outlets are provided and independently regulated in order to provide from a single high pressure source dual intermediate pressure air for delivery to second stage regulators. In combination with second stage regulators, a system is provided which has enhanced safety features.

A first stage pressure regulator for use with a high pressure source of breathable gas, said first stage pressure regulator comprising:
- a housing
- means for attaching said housing to a high pressure source of breathable gas;
- a first pressure regulated outlet;
- a second pressure regulated outlet;
- first means disposed within said housing for delivery to said first pressure regulated outlet a supply of breathable gas at a pressure lower than the high pressure source;
- second means, disposed within said housing and operationally independent from said first means, for delivering to said second pressure regulated outlet a supply of breathable gas at a pressure lower than the high pressure source;
- and
- first spring means for biasing said first piston in order to effect a first regulated valve opening between the first piston open end means and the fixed valve seat member and second spring means for biasing said second piston in order to effect a second regulated valve opening between the second piston open end means and the fixed valve seat member.
A first stage pressure regulator for use with a high pressure source of breathable gas, said first stage pressure regulator comprising:
- a housing;
- means for attaching said housing to a high pressure source of breathable gas;
- first body means attached to said housing for providing plurality of first pressure regulated outlets;
- second body means attached to said housing for providing a plurality of second pressure regulated outlets;
- first means for delivering to said plurality of first pressure regulated outlets a supply of breathable gas at a pressure lower than the high pressure source;
- second means, operationally independent from said first means, for delivery to said plurality of second pressure regulated outlets a supply of breathable gas at a pressure lower than the high pressure source;
- and
- first spring means for biasing said first piston in order to effect a first regulated valve opening between the first piston open end means and the fixed valve seat member and second spring means for biasing said second piston in order to effect a second regulated valve opening between the second piston open end means and the fixed valve seat member.
A first stage pressure regulator for use with a high pressure source of breathable gas, said first stage pressure regulator comprising:
- a housing;
- means for attaching said housing to a high pressure source of breathable gas;
- outlet means for delivering a supply of breathable air, at a pressure lower than said high pressure source, to a second stage regulator;
- a valve seat member fixed within said housing;
- a piston having a hollow center in fluid communication with said outlet means and open end means for seating said piston against the fixed valve seat member;
- spring means for biasing said piston in order to effect a regulated valve opening between said open end means and the fixed valve seat;
- and
- secondary spring means for adjusting the amount of bias provided by said spring means in order to regulate the pressure of the supply of breathable gas at a pressure lower than said high pressure source.
A SCUBA regulator system for use with a single high pressure source of breathable gas, the system comprising:
- a single first stage pressure regulator having first and second pressure regulated outlets, said single first stage pressure regulator being adapted for connection to said single high pressure source of breathable gas and including means for independently delivering to said first and second pressure regulated outlets a supply of breathable gas at an intermediate pressure, said intermediate pressure being lower than the pressure of the single high pressure source of breathable gas;
- and
- two second statue pressure regulator means for receiving intermediate pressure breathable air from the first and second pressure regulated outlets and delivering breathable air to at least one mouthpiece at a pressure suitable for a SCUBA diver.
