ABSTRACT:
A breakaway hose coupling according to which a removable housing is detachably connected to a fixed housing. A sealing member in the fixed housing is urged towards a seat in the fixed housing to prevent fluid flow through the fixed housing, and a member in the second housing is urged into engagement with the sealing member in the first housing to urge the latter sealing member away from the seat. The connection between the housings is released in response to a predetermined force acting on the second housing and the member in the second housing disengages from the sealing member in the first housing. As a result, the sealing member in the first housing is urged against the seat to prevent fluid flow through the fixed housing.
