초록 ▼

A fluid pressure regulator and method of regulating high pressure fluid from a container such as high pressure gas cylinder, compensate for variation in the supply pressure to the regulator to limit variation in the outlet pressure of the regulator due to supply pressure variations. A flexible valve seat of the regulator is mounted in the regulator so that the seat can flex in response to changes in the supply pressure to change the operating point of the valve seat concurrently with changes in the balance of forces on a diaphragm of the regulator caused by changes in the supply pressure to the regulator. Advantageously, the regulator and method eliminate the need for using two stage regulators for minimizing outlet pressure variations due to the supply pressure effect.

In the method of regulating the fluid pressure dispensed from a container of pressurized fluid, such as a high pressure gas cylinder, using a fluid pressure regulator having a fluid passage for the flow of pressurized fluid, a valve movably positioned in the regulator for adjustably throttling the fluid passage and the flow of pressurized fluid therethrough, a diaphragm which can be deflected in response to a force imbalance thereon for moving said valve, a spring for applying a first force on the diaphragm in a first direction, pressurized fluid downstream of said throttled passage applying a second force on the diaphragm in a second direction opposite said first direction, a third force being applied to said diaphragm in said second direction by way of said valve, said third force being a function of the pressure of said fluid supply to said throttled passage which acts on said valve and a valve seat having an aperture extending therethrough which defines a portion of said fluid passage, the valve cooperating with said valve seat about the aperture for adjustably throttling said fluid passage, the improvement comprising forming the valve seat of a flexible material and mounting the valve seat in the regulator for flexural movement of the valve seat in response to changes in the pressure of the fluid supplied to the throttled passage of the regulator from said pressurized fluid container which acts on the valve seat to substantially reduce changes in the pressure of fluid downstream of the throttled passage with movement of the diaphragm and valve as a result of force imbalances on the diaphragm caused by changes in the pressure in said container.
