Pressurized fluid coupler with anti-recoil feature and methods
First Claim
1. A coupler fitting for high pressure fluids comprising:
- a body having an axis and defining a passage from a proximal end through which fluid enters the body to a distal end through which fluid exits the body, and further defining a first cavity;
a check valve openable by a force directed towards the proximal end of the body and occupying the first cavity;
a probe exposed at a proximal end to the check valve and extending at a distal end past the first cavity; and
a collar at least partially surrounding the body and defining a portion of a second cavity at the distal end of the body into which the distal end of the probe extends, wherein a fluid pathway is created between the second cavity and an ambient environment through at least one port defined by the collar having a direction of fluid exit not equal to the axial direction of the coupler fitting.

Abstract
The invention is directed to apparatus and methods for reducing recoil during uncoupling of pressurized couplers. The apparatus includes a male: a female component; and a check valve fluidly disposed between a proximal end and a distal end within one of the male component or female component. When the component including the check valve is pressurized, the check valve assumes a normally closed state. Upon coupling of the male component with the female component, the check valve is caused to open through the interaction of a probe linked to the check valve which contacts a portion of the opposing coupler, thereby opening the check valve and permitting pressurized fluid flow between the two components. At least one radially directed port fluidly couples the interface between the male and female couplers with the environment, which may be formed in one or both couplers.
