Abstract
A pressure regulator comprising a body portion having an inlet port, an outlet port, and a flow passage positioned therebetween is provided. A valve member and a valve seat are positioned in the flow passage. A spring is coupled to the valve member to urge the valve member along an axis towards the valve seat, wherein the flow passage is substantially closed when the valve member engages with the valve seat. The spring has an extended segment in contact with a fixed surface, whereby the extended segment restricts displacement of the spring in a direction substantially perpendicular to the axis.
