Abstract
A regulator is adapted to connect to a gas cylinder, particularly at a location upstream of a cylinder valve, and the regulator may include at least one of a filling slide component, oscillation damper, charge port, and a reset assembly. The regulator includes a body enclosing a cavity, and an inlet passage configured to attach to an associated gas cylinder and an outlet passage configured to attach to an associated cylinder valve, the inlet and outlet passages in selective fluid communication with one another. A flexible diaphragm/bellows is interposed between the inlet and outlet passages. A poppet assembly is located between the inlet and outlet passages that selectively seals with a poppet seat to regulate fluid flow between the inlet and outlet passages.
Claims19
A regulator comprising:
- a body enclosing a cavity, and an inlet passage configured to attach to an associated gas cylinder and an outlet passage configured to attach to an associated cylinder valve, the inlet and outlet passages in selective fluid communication with one another;
- first and second flexible diaphragms or bellows interposed between the inlet and outlet passages that form a pressure chamber therebetween;
- a poppet assembly located between the inlet and outlet passages that selectively seals with a poppet seat to regulate fluid flow between the inlet and outlet passages;
- and
- a charge port that selectively communicates from external to the body with the pressure chamber between the first flexible diaphragm or bellows and the second flexible diaphragm or bellows to set or reset a pressure in the pressure chamber.
A regulator comprising:
- a body enclosing a cavity, and an inlet passage configured to attach to an associated gas cylinder and an outlet passage configured to attach to an associated cylinder valve, the inlet and outlet passages in selective fluid communication with one another;
- a flexible diaphragm or bellows interposed between the inlet and outlet passages;
- a poppet assembly located between the inlet and outlet passages that selectively seals with a poppet seat to regulate fluid flow between the inlet and outlet passages, wherein the poppet assembly includes a poppet stem connected to a poppet and to the flexible diaphragm or bellows;
- and
- a component having first and second states, the first state limiting flow in a gas cylinder filling direction from the outlet passage to the inlet passage of the regulator, and a second state permitting flow in the gas filling direction.
A regulator comprising:
- a body enclosing a cavity, and an inlet passage configured to attach to an associated gas cylinder and an outlet passage configured to attach to an associated cylinder valve, the inlet and outlet passages in selective fluid communication with one another;
- a flexible diaphragm or bellows interposed between the inlet and outlet passages;
- a poppet assembly located between the inlet and outlet passages that selectively seals with a poppet seat to regulate fluid flow between the inlet and outlet passages;
- an excess flow valve received in the body between the inlet passage and the outlet passage, the excess flow valve including a shut off poppet that selectively engages an excess flow valve seat;
- a reset mechanism that selectively engages the excess flow valve and moves the excess flow valve shut off poppet from an engaged position with the excess flow valve seat, wherein the reset mechanism includes a hard member mounted on the excess flow valve shut off poppet, and the reset mechanism includes a piston that selectively engages the hard member to move the excess flow valve shut off poppet from the engaged position with the excess flow valve seat, and wherein the reset mechanism includes a tube that slidingly receives the piston therein, and the piston includes a first magnet therein and the reset mechanism includes a second magnet located externally of the regulator body.
