Abstract
A quick change, self-contained vacuum system includes a debris container with an input opening and a pressure head that is configured to receive a fluid under a high pressure and which includes a low pressure inlet and an exhaust port. A guide pin may be provided along with a body that is selectively engageable with the pressure head and the guide pin. The body includes 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. The vacuum system further includes a shutoff valve that is operable in response to movement of the guide pin. In operation, movement of the guide pin relative to the body in one direction establishes locking engagement of the pressure head and the body along with a 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. Movement of the guide pin 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 bore and the input o…
