Abstract:
A quick change, self-contained vacuum system having a debris container with an input opening, comprising:a pressure head configured to receive a fluid under a high pressure and comprising a low pressure inlet and an exhaust port; a guide; a debris container comprising an input opening; a body being selectively engageable with the pressure head and the guide and comprising a bore having a first port communicating with the exhaust port of the pressure head and a second port communicating with the input opening of the debris container; and a shutoff valve being operable in response to movement of the guide relative to the body; wherein movement of the guide relative to the body in one direction establishes locking engagement of the pressure head and the body along with response by the shutoff valve to establish fluid communication between the exhaust port of the pressure head and the input opening of the debris container and movement of the guide relative to the body in another direction provides for separation of the pressure head and the body and response by the shutoff valve to prevent fluid communication between the first port of the body and the input opening of the debris container.
