Abstract
A fluid coupling includes an inlet housing member, an outlet housing member rotatably connected with the inlet housing member to define a chamber, a regulator assembly disposed in the chamber and connected to the outlet housing member, a main poppet configured to control fluid flow between the inlet housing member and the outlet housing member, and/or a pilot poppet configured to selectively permit fluid flow through the main poppet. The outlet housing member may be configured to mate with and at least partially receive a nozzle. The regulator assembly may include a regulator housing and a regulator.

A fluid coupling, comprising:
- an inlet housing member;
- an outlet housing member rotatably connected with the inlet housing member to define a chamber, the outlet housing member configured to connect or mate with and at least partially receive a fluid nozzle;
- a regulator assembly disposed in the chamber and connected to the outlet housing member, the regulator assembly including a regulator housing and a regulator;
- a main poppet configured to control fluid flow between the inlet housing member and the outlet housing member;
- and
- a pilot poppet configured to selectively permit fluid flow through the main poppet;
- wherein the regulator, the main poppet, and the pilot poppet close in the same direction.
