ABSTRACT:
A self-releasing clamp for a fluid carrying hose comprises an inclined guide and a roller carried by the guide which is movable along the guide between a hose releasing position and a hose clamping position. There is a hose support for holding the hose against the roller. A mechanism provides a space between the roller and the hose support when the roller is in the clamping position. The space providing mechanism permits a limited flow of fluid past the clamp to increase pressure in the hose downstream from the clamp when the fluid flow downstream from the clamp is stopped, expanding the hose between the hose support and the roller and moving the roller to the hose releasing position.
