Abstract
A pressure regulator apparatus includes a fluid passage and a movable member configured to be positioned within the fluid passage such that a gap is formed between the movable member and a surface of the fluid passage. The movable member is adapted to travel within the fluid passage with the size of the gap increasing as the movable member travels in a direction of a fluid flow path.
Claims22
A pressure regulator apparatus comprising:
- a structure including a fluid passage with a fluid inlet port and a fluid outlet port, the fluid passage including a surface defining a fluid flow path in a direction from the fluid inlet port toward the fluid outlet port, wherein the fluid passage includes a cross sectional area that increases in the direction of the fluid flow path;
- and
- a movable member configured to be positioned within the fluid passage such that a gap is formed between the movable member and the surface of the fluid passage, wherein the movable member is adapted to travel within the fluid passage with the size of the gap increasing as the movable member travels in the direction of the fluid flow path.
A pressure regulator apparatus including:
- a fluid passage for establishing a fluid path between a fluid inlet port and a fluid outlet port,
- a movable member configured to travel within the fluid passage for maintaining a substantially constant predetermined pressure of a first fluid zone with respect to a second fluid zone at a pressure range from about 0.25 inches of water to about 5 inches of water, while fluid flows from the fluid inlet port to the fluid outlet port.
A pressure regulator apparatus including:
- a fluid passage for establishing a fluid path between a fluid inlet port and a fluid outlet port,
- a movable member configured to travel within the fluid passage, in accordance with the equation
