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 disengaging force of a preselected value is disclosed. The coupling device (10) comprises a coupling sleeve (12) defining at least one shear pin hole (18) for receiving a shear pin (54) having a preselected shear strength. The coupling device (10) further comprises first and second valve assemblies (20 & 22) each comprising a valve housing (24, 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 & 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 shear pin hole (18) as the valve housing is received in the sleeve (12), whereby the shear pin (54) is received in the shear pin hole (18) and extends into a swivel ring member (52) rotatably mounted within the annular recess (52) thereby limiting the axial movement of said valve housing while allowing the valve housing to rotate within the coupling sleeve (12).
