ABSTRACT:
A breakaway hose coupling device (10') for releasably joining the hose ends of two fluid communicating hoses and for selectively disengaging and sealing such hose ends in response to a disengaging force of a preselected value is disclosed. The coupling device (10') comprises a coupling sleeve (12') defining an interior surface provided with an annular groove (80). The coupling device (10') further comprises first and second valve assemblies (20'and 22') each comprising a valve housing (24'and 25') having a forward end portion (26') for being received in the opposite ends of the coupling sleeve (12'), and a rearward end portion defining a threaded receptor (34') for engaging a hose end. Each valve housing is also provided with a passageway (30') therethrough communicating with the hose end, the passageway (30') defining a forwardly disposed valve seat (32'). Each of the valve assembly (20'and 22') further comprising a spring biased poppet valve (58') mounted within the passageway (30'). The valve housing (24',25') of one valve assembly (20',22') is provided with an annular recess (52') registering with the annular groove (80) as the valve housing is received in the sleeve (12'), the annular recess (52') being receptive of a coupling spring (82) which biases outwardly such that the outer radial portion (84) of the spring (82) is releasably received in the annular groove (80).
