ABSTRACT:
A pressure regulator comprising a housing, a pivoting lever selectively covering a passage between an inlet port and an outlet port of the housing, a diaphragm interconnected to the lever to rotate the lever in reaction to pressure levels in the housing, and a closure member abutting the pivoting lever and covering the passage to prevent fluid flow through the passage. The pressure regulator can have the closure member not being directly connected to the lever, a stabilizer element frictionally abutting a pivot pin as the lever rotates to thereby stabilize movement of the lever, an adjustment member that translates rotational movement of an adjustment cap into compression or decompression of a biasing element without applying a rotational force to the biasing element, and/or the cap including a tab configured to be selectively inserted at least one slot on the housing to prevent rotation of the adjustment cap.
