Patent number: 7086271Abstract: A test device and method for drawing a vacuum relative to an ambient environment. The device includes a member defining a passage, a valve, and a fluid communication conduit. The passage extends between a first end and a second end, and includes a constriction defining an orifice. The first end is in fluid communication with an ambient environment. The valve has a first port and a second port. The first port is adapted for fluid communication with a pressure source at a first pressure level. The fluid communication conduit includes a fluid communication tap at a second pressure level. The second pressure level is responsive to fluid flow through the orifice. The fluid communication conduit connects the second end of the member and the second port of the valve.Type: GrantFiled: June 16, 2004Date of Patent: August 8, 2006Assignee: Siemens VDO Automotive Inc.Inventors: Kevin Tetreault, John Derikx

Patent number: 6938456Abstract: A vacuum generating device and method include a member that defines a passage, a first valve, a second valve, a fluid communication conduit, a transducer, and a processor. The passage extends between a first end and a second end, and includes a constriction that defines an orifice. The first valve connects the first end of the member and an ambient environment, and is electrically positionable in first and second configurations. The first configuration permits generally unrestricted fluid flow between the orifice and the ambient environment, and the second configuration substantially prevents fluid flow between the orifice and the ambient environment. The second valve has a first port and a second port. The first port is adapted for fluid communication with a pressure source at a first pressure level. The second valve is electronically adjustable. The fluid communication conduit connects the second end of the member and the second port of the second valve.Type: GrantFiled: June 16, 2004Date of Patent: September 6, 2005Assignee: Siemens VDO Automotive Inc.Inventors: Kevin Tetreault, John Derikx
