Abstract
A pressure regulator manages fluid pressure along a pathway between an inlet port and an outlet port. A poppet opens and closes the pathway within the regulator. In certain regulators, a biasing member biases the poppet in common direction with the inlet port. In certain regulators, the poppet defines a through passage to route the fluid past the biasing member. In certain regulators, an adjustment interface arrangement enables a user to set what fluid pressure level closes the pathway by changing a pre-load applied to the poppet.
Claims20
A pressure regulator comprising:
- a housing defining an inlet region, an outlet region, and a regulating region, the inlet and outlet regions being separated by a first passage, the inlet region being configured to receive inlet pressure along a first direction;
- a poppet disposed within the housing, the poppet extending along a length between first and second ends, the first end being disposed at the outlet region and the second end being disposed at the regulating region, the poppet being movable relative to the housing between open and closed positions, the poppet sealing closed the first passage when the poppet is disposed in the closed position and the poppet opening the first passage when the poppet is moved towards the open position, the poppet defining a second passage fluidly connecting the outlet region and the regulating region;
- and
- a first biasing member biasing the poppet along the first direction towards the open position.
A method of operating a pressure regulator comprising:
- directing gas through an inlet of the pressure regulator along a first direction;
- directing gas through a passage to an outlet region of the pressure regulator;
- directing a first portion of the gas within the outlet region out of the pressure regulator through an outlet;
- directing a second portion of the gas within the outlet region through a poppet to a regulating region;
- applying a closing force to the poppet using the second portion of the gas, the closing force being applied in a second direction that is opposite the first direction.
A pressure regulator comprising:
- a housing defining an inlet region, an outlet region, and a regulating region, the housing also defining a passage between the inlet region and the outlet region;
- a poppet disposed within the housing, the poppet being movable relative to the housing along an axis between open and closed positions, the poppet sealing closed the passage when the poppet is disposed in the closed position and the poppet opening the passage when the poppet is moved towards the open position;
- and
- a first biasing member biasing the poppet to the open position;
- a stop disposed at the regulating region, the stop being selectively positionable along the axis within the regulating region;
- and
- a second biasing member disposed between the stop and the poppet.
