RATCHETING HOSE NUT FOR A FLUID DELIVERY DEVICE

摘要

A hose nut for coupling a fluid delivery device to a fluid conduit is provided. In one embodiment, the hose nut includes a pawl configured to rotate about a hinge between a locked position and an unlocked position. The hose nut is configured to rotate in a first tightening direction relative to the fluid delivery device and a second loosening direction opposite the first tightening direction when the pawl is in the unlocked position, and the pawl is configured to radially engage the fluid delivery device to move the pawl to the unlocked position during rotation in the first tightening direction and the pawl is configured to engage the fluid delivery device to resist rotating in the second loosening direction when the pawl is in the locked position.
