Abstract
A pressure operable device for an integrated pressure management apparatus. The pressure operable device includes a poppet moving between a first configuration permitting fluid communication between first and second ports of the integrated pressure management apparatus, and a second configuration preventing fluid communication between the first and second ports. A spring biases the poppet toward the second configuration, and a diaphragm operably engages the poppet to move the poppet toward the first configuration.
Claims8
A pressure operable device for an integrated pressure management apparatus having first and second fluid ports in fluid communication with an interior chamber, the pressure operable device comprising:
- a poppet movable between first and second configurations, the first configuration being adapted for permitting fluid communication between the first and second ports, and the second configuration being adapted for fluidly isolating the first and second ports from each other;
- a spring biasing the poppet toward the second configuration;
- and
- a diaphragm operably engaging the poppet to move the poppet toward the first configuration, the diaphragm adapted to separate a signal chamber in fluid communication with the first port from an interior chamber portion in fluid communication with the second port.
A pressure operable device for an integrated pressure management apparatus having first and second fluid ports in fluid communication with an interior chamber, the pressure operable device comprising:
- a poppet movable between first and second configurations, the first configuration being adapted for permitting fluid communication between the first and second ports, and the second configuration being adapted for fluidly isolating the first and second ports from each other, a negative pressure at the first port that is below a first pressure level displacing the poppet to the first configuration;
- a spring biasing the poppet toward the second configuration;
- and
- a diaphragm operably engaging the poppet to move the poppet toward the first configuration.
A pressure operable device for an integrated pressure management apparatus having first and second fluid ports in fluid communication with an interior chamber, the pressure operable device comprising:
- a poppet movable between first and second configurations, the first configuration being adapted for permitting fluid communication between the first and second ports, and the second configuration being adapted for fluidly isolating the first and second ports from each other, the poppet occluding a second area;
- a spring biasing the poppet toward the second configuration;
- and
- a diaphragm operably engaging the poppet to move the poppet toward the first configuration, the diaphragm occluding a first area, a ratio of the first area to the second area greater than 9.5.
