Abstract
A flow-through pressure regulator includes a housing having an inlet and an outlet offset along a longitudinal axis. The housing is separated by a divider into a first chamber and a second chamber. The divider has a passage that communicates the first chamber with the second chamber. The passage includes a first section extending along the longitudinal axis and a second section extending transverse to the longitudinal axis. A closure member permits or inhibits flow through the passage.
Claims20
A flow-through pressure regulator, comprising:
- a housing having an inlet and an outlet offset along a longitudinal axis;
- a divider separating the housing into a first chamber and a second chamber, the divider having a passage that communicates the first chamber with the second chamber, the passage including a first section along the longitudinal axis and a second section extending transverse to the longitudinal axis, the first section providing a first communication path between the first chamber and the second chamber, and the second section providing a second communication path between the first section and the second chamber;
- a closure member that permits or inhibits flow through the passage.
A seat for a flow-through regulator, the seat comprising:
- a first seat portion having a first surface disposed about a longitudinal axis;
- a second seat portion having a second surface offset from the first surface along the longitudinal axis;
- a side surface disposed between the first surface and the second surface;
- and
- a passage having a first section and a second section, the first section of the passage extending along the longitudinal axis in both the first portion and the second portion of the seat, the second section of the passage extending transverse to the longitudinal axis in the second portion of the seat, the first section including a first wall communicating with the first surface and the second surface, and the second section comprising a second wall and a third wall communicating with the first wall and the side surface.
A method of inversely correlating maximum pressure and flow values of a flow-through regulator while stabilizing noise generation of the flow-through regulator, the flow-through regulator including a housing with an inlet and an outlet offset along a longitudinal axis, a divider separating the housing into a first chamber and a second chamber, the divider including a passage that provides communication between the first chamber and the second chamber, and a closure member that permits or inhibits flow through the passage, the method comprising:
- establishing a first communication path between the first chamber and the second chamber with a first section of the passage extending along the longitudinal axis;
- and
- establishing a second communication path between the first section and the second chamber with a second section of the passage extending transverse to the longitudinal axis.
The method of claim of 17, further comprising:
- providing a seat in the divider, the seat having a first seat portion and a second seat portion, the first seat portion and the second seat portion being disposed along the longitudinal axis, the first seat portion being disposed in the first chamber and the second seat portion being disposed in the second chamber;
- and
- locating the passage between the first seat portion and the second seat portion to provide communication between the first chamber and the second chamber.
