Abstract (en)
[origin: WO8604130A1] A coupling device, which can be connected or disconnected quickly, capable of operation in both high and low pressure environments, and in applications where shock and extreme vibrations may be present. Interconnection is accomplished via complimentarily-threaded male and female (100) members. These members each contain an inner (21) (121) and outer valve (49) (149) assembly, arranged in such a manner that the inner valves (21) (121) open prior to the opening of the outer valves (49) (149), thus permitting equalization of pressure (termed "venting") to develop between the male and female (100) sides of the coupling before fluid flow is initiated. Ease of manufacture is facilitated through modularized valving and spring biased (91) (191) structure, while the device's symmetrical design allows for complete reversibility of inputs and outputs. The instant coupling is intended for use with hydraulic and/or other types of fluid flow lines, particularly where said lines may be under pressure.
