Abstract
A high pressure fluid storage system with at least one pressure sensing unitary device (PSUD) which can perform the function of a pressure regulator device. The PSUD can be manufactured as a single unitary construction, wherein both the housing body and the internal pressure regulating mechanism are made from a single unit, material, or both. The PSUD does not have any welded components, is not assembled from a plurality of separate components, or both.
Claims15
A device comprising:
- a single unitary body, which includes:
- a housing,
- wherein the housing includes:
- an inlet, and
- an outlet;
- and
- a pressure reducing mechanism, which is contained within the housing, and is disposed between the inlet and the outlet,
- wherein the pressure reducing mechanism includes a diaphragm portion connected to a valve,
- wherein the pressure reducing mechanism is configured to receive a fluid having a first pressure which enters via the inlet, direct a flow of the fluid towards the outlet at a second pressure.
The device of claim 2, wherein the pressure reducing mechanism further comprises a stem,
- wherein the valve includes a poppet valve,
- wherein a first end of the stem is connected to one side of the diaphragm portion,
- a second end of the stem is connected to the poppet valve,
- wherein the pressure reducing mechanism operates such that the poppet valve is in an open state when the diaphragm portion flexes towards the inlet, and the poppet valve is in a closed state when the diaphragm portion is at rest or flexes towards the outlet.
A fluid supply system comprising:
- a container body, which defines an internal cavity for storing a fluid at a first pressure;
- and
- a pressure regulator device, which is disposed in the internal cavity, and is a single unitary body,
- wherein the single unitary body includes:
- a housing, which includes:
- an inlet, and
- an outlet;
- and
- a pressure reducing mechanism, which is contained within the housing,
- and is disposed between the inlet and the outlet,
- wherein the pressure reducing mechanism includes a diaphragm portion connected to a valve, and
- wherein the pressure reducing mechanism is configured to receive the fluid having the first pressure which enters via the inlet, direct a flow of the fluid to the outlet at a second pressure,
- wherein the second pressure is lower than the first pressure.
