Abstract:
1. A breakaway coupler for coupling an upstream hose with a downstream hose for passing fluid therebetween when coupled and closing flow when uncoupled, the breakaway coupler comprising: an upstream housing securable to the upstream hose; an upstream coupling member secured to the upstream housing and having a flow passage for fluid communication with the upstream hose; a downstream housing securable to the downstream hose; a downstream coupling member secured to the downstream housing and having a flow passage for fluid communication with the downstream hose; a locking member carried by one of the upstream and downstream coupling members and a receiving member defined by the other of the upstream and downstream coupling members, the locking member radially movable into and out of the receiving member to respectively lock and unlock the upstream and downstream coupling members; a trigger member radially outward of the locking member and having one or more inwardly facing unlocking recesses into which the locking member is movable to unlock the upstream and downstream coupling members; a trigger spring axially biasing the one of the upstream and downstream coupling members on which the locking member is carried; and an outwardly facing pry recess on the one of the upstream and downstream coupling members on which the locking member is carried, such that a tool inserted into the pry recess is leverageable to move the locking member toward the one or more unlocking recesses.
