Abstract
The flexible hose assembly interconnects a portable tank and another tank for transmitting hazardous fluids. A back check housing contains a valve member and a seating surface for closing off flow through the back check housing. A flexible hose extends downstream from the back check housing, and a flexible sensing line extends within the flexible hose downstream from the back check housing for transmitting fluid pressure to a piston . The piston is axially movable between a locked and unlocked position, and when in a locked position maintains the valve member in the open flow position and when in the unlocked position allows the valve member to move to the closed position. A biasing member is provided for biasing at least one of the piston and valve members to the unlocked position.
