Abstract

Abstract An improved coupling mechanism includes an actuator assembly which is manually operable to connect and disconnect a coupling having valves which are biased closed by fluid pressure. The actuator assembly includes a lever which is pivotally mounted on one coupling member. A linkage connected to the actuator lever is engageable with the other coupling member. Once the linkage has been engaged with the other coupling member, the lever is pivoted to actuate the linkage and move the coupling members toward each other to a connected condition. Simultaneously therewith, the valves are operated to the open condition against the influence of the fluid pressure bias to thereby connect the conduits in fluid communication. A second linkage is connected with the actuator lever to operate a coupling retainer or latch assembly to a release condition to facilitate disconnection of the coupling.
