US 9,958,879 B2 · Gas pressure regulator

Abstract

A gas pressure regulator (10) is disclosed, comprising a body (12) fitted with a gas inlet stem (14), at a first end of the body (10), for receiving gas from a gas source at a first pressure, and a gas outlet stem or adaptor (16) at a second end of the body (10), for supplying gas at a desired pressure at the gas outlet stem (16). A pressure adjusting mechanism (18) is provided to enable a user to adjust and set the desired pressure, the pressure adjusting mechanism (18) comprising a movable piston arrangement (20). The gas pressure regulator (10) further comprises gas regulating means (22), to regulate gas flowing out of the gas outlet stem (16) to achieve the desired pressure set by the user. The gas regulating means (22) is securely fitted within the body (12) so as to be located within a gas flow path between the gas inlet stem (14) and the gas outlet stem (16), the gas regulating means (22) comprising an encapsulated valve (24) with a lever (26) that can be actuated by the movable piston arrangement (20) of the pressure adjusting mechanism (18).

Dependent claims

A gas pressure regulator, comprising:

a body fitted with a gas inlet stem, at a first end of the body, for receiving gas from a gas source at a first pressure, and a gas outlet stem or adaptor at a second end of the body, for supplying gas at a desired pressure at the gas outlet stem or adaptor;
a pressure adjusting mechanism to enable a user to adjust and set the desired pressure, the pressure adjusting mechanism comprising a movable piston arrangement, wherein the pressure adjusting mechanism comprises a venting sleeve that defines at least one venting aperture to enable gas to vent if/when required, the venting sleeve at least partially housing the piston arrangement;
and
gas regulating means, to regulate gas flowing out of the gas outlet stem or adaptor to achieve the desired pressure set by the user, wherein the gas regulating means is fitted within the body so as to be located within a gas flow path between the gas inlet stem and the gas outlet stem or adaptor, the gas regulating means comprising an encapsulated valve with a lever actuated by the movable piston arrangement of the pressure adjusting mechanism.

A pressure adjusting mechanism for a gas pressure regulator, to enable a user to adjust and set the desired pressure, wherein the pressure adjusting mechanism comprises:

a movable piston arrangement that actuates a lever of a valve within the gas pressure regulator;
and a pressure adjusting assembly manually operated by a user to adjust and set the desired pressure, the pressure adjusting assembly comprising a rotatable knob to actuator a movable spindle, which in turn actuates first biasing means for actuating the piston arrangement and a venting sleeve that defines at least one venting aperture to enable gas to vent if/when required, the venting sleeve at least partially housing the piston arrangement.

A gas pressure regulator, comprising:

a body fitted with a gas inlet stem, at a first end of the body, for receiving gas from a gas source at a first pressure, and a gas outlet stem or adaptor at a second end of the body, for supplying gas at a desired pressure at the gas outlet stem or adaptor;
a pressure adjusting mechanism to enable a user to adjust and set the desired pressure, the pressure adjusting mechanism comprising a movable piston arrangement;
and gas regulating means, to regulate gas flowing out of the gas outlet stem or adaptor to achieve the desired pressure set by the user, wherein the gas regulating means is fitted within the body so as to be located within a gas flow path between the gas inlet stem and the gas outlet stem or adaptor, the gas regulating means comprising an encapsulated valve with a lever actuated by the movable piston arrangement of the pressure adjusting mechanism, wherein the encapsulated valve of the gas regulating means comprises:
a valve body having an inlet side and an outlet side, the lever being pivotally fitted at the outlet side with a pivot pin, the lever having an actuating cam, proximate the pivot pin;
a capsule valve pin for abutting against the actuating cam of the lever, the capsule valve pin further including a seat to sealingly engage a flow aperture defined in an inner wall within the valve body, the capsule valve pin being movable between a default, closed position in which the lever is not actuated by the movable piston arrangement of the pressure adjusting mechanism and in which the seat seals against the flow aperture, so as to prevent the flow of gas through the flow aperture, and an actuated, open position in which the lever is moved by the movable piston arrangement of the pressure adjusting mechanism, with the actuating cam moving the capsule valve pin so that the seat moves away from the flow aperture so as to allow the flow of gas through the flow aperture;
and first biasing means to bias the capsule valve pin towards the default, closed position.
