US 2021/0141402 A1 · Low Profile Pressure Regulator

Abstract

A pressure regulator includes an inlet channel, an outlet channel, a bladder, a first plate, and a second plate. The bladder is connected to the outlet channel and extends alongside of the inlet channel. The first plate is disposed on one side of the inlet channel between the bladder and the inlet channel. The second plate is disposed on the other side of the bladder and is at least partially aligned with the first plate along the length of the inlet channel such that a portion of the inlet channel is disposed between the first and second plates. When the bladder is pressurized, the bladder urges the first plate toward the second plate and thereby pinches the portion of the inlet channel disposed between the first and second plates to regulate a ratio of a pressure in the outlet channel to a pressure in the inlet channel.

A pressure regulator comprising:

an inlet channel;
an outlet channel configured to receive gas from the inlet channel;
a bladder configured to receive gas from the outlet channel and extending alongside of the inlet channel;
a first plate disposed on one side of the inlet channel between the bladder and the inlet channel;
and
a second plate disposed on the other side of the bladder and at least partially aligned with the first plate along the length of the inlet channel such that a portion of the inlet channel is disposed between the first and second plates, wherein when the bladder is pressurized, the bladder urges the first plate toward the second plate and thereby pinches the portion of the inlet channel disposed between the first and second plates to regulate a ratio of a pressure in the outlet channel to a pressure in the inlet channel.
