Quick coupler adapter
First Claim
1. An apparatus for releasing pressure from a conduit having a check valve in the proximity of a connection fitting, said apparatus comprisinga body having an exterior surface adapted to removably engage an interior surface of a mating fitting for further mating with said connection fitting, said body having an internal axial bore, and a pressure release mechanism engaging with a portion of said internal axial bore at a screw threaded outer surface portion of said pressure release mechanism, said pressure release mechanism further having an axially extending fluid passage therein, a non-axial aperture in fluid communication with said axially extending fluid passage and a portion for axially engaging said check valve.

Abstract
A adapter provides for connection of a pressure relief mechanism to a connection fitting portion of a quick connect fitting through a mating connection fitting portion and provides for movement of the pressure relief mechanism against a check valve in a hydraulic fluid conduit through a screw thread connection to the adapter. When the check valve is thus opened fluid flow is provided substantially axially through the pressure relief mechanism, thereby reducing the likelihood of disengagement of respective portions of the quick connect fitting when hydraulic fluid is present. Collection of hydraulic fluid in a vessel connected to the pressure relief mechanism is provided to allow recycling of the fluid and to prevent release of the fluid into the environment.

8. A method for depressurizing a conduit having a check valve therein, said method including steps of
connecting an adapter to a portion of a connection fitting for connection to a mating portion of another connection fitting connected to said conduit, applying force to said check valve along an axis of said adapter, and releasing fluid from said check valve to flow through said adapter in a direction substantially axial of said adapter.
