Abstract
A variable capacity refrigeration system and a fluid flow control device particularly well suited for use therewith. The fluid flow control device includes a body, a Belleville spring, and a plug. The body defines a fluid flow passage, and the plug is secured therewithin. The Belleville spring is positioned within the fluid flow passage and includes an inside edge defining a radially extending spring port for conducting fluid through the spring. The Belleville spring has a normal position, where the inside edge of the spring engages the plug to close the spring port, and an overcenter position, where the inside edge of the spring is spaced from the plug to allow fluid flow through the spring port.
