Patent number: 7299994Abstract: A valve actuating mechanism for a transmission/engine fluid cooler bypass valve of the type in which a responsive element expands to urge a valve member against a valve seat and thereby causes transmission fluid to flow through an oil fluid cooler. A cast valve housing is utilized which is interposed between the cooler and the oil source. The valve actuating mechanism is designed to allow fluid to pass through the valve once the fluid has reached an elevated pressure level.Type: GrantFiled: August 26, 2005Date of Patent: November 27, 2007Assignee: Huron, Inc.Inventors: Lanny D. Brown, John S. Leen

Patent number: 7044150Abstract: A bidirectional valve comprising a flexible member with an aperture formed therein. The flexible member reacts to differential pressure thereacross by deforming, thereby causing the inside surfaces of the aperture to separate and create a vent path. The bidirectional valve can be tuned to open the aperture in reaction to varied differential pressures thereacross, thereby allowing a fluid to pass through the aperture.Type: GrantFiled: June 27, 2003Date of Patent: May 16, 2006Assignee: Huron, Inc.Inventor: Gerard L. Seidl

Patent number: 6581583Abstract: In accordance with the teachings of the present invention, an off gas emission engine intake system is provided which uses engine cooling fluid to deliver warm emission gasses to the engine. The heater provides an outer body which has a channel therethrough. The channel is defined by an annular inner surface. An emission intake tube is disposed through the channel defining a toroidal chamber between the inner surface and air intake tube. The outer body further defines a pair of opposed orifices which accept coolant into the toroidal chamber. The system further has a lower extension tube which journally accepts the emission intake tube. A cylindrical chamber, coupled to the toroidal chamber, to further increase the contact area between the intake fluid.Type: GrantFiled: May 16, 2002Date of Patent: June 24, 2003Assignee: Huron, Inc.Inventor: John S. Leen

Patent number: 5595213Abstract: A fluid connector assembly includes a male member, a female member and a one-way check valve. A first resilient elastomeric member is disposed between the male and female members for retaining the connection between the two members. A second resilient elastomeric member is disposed between the male and female members for sealing the connection between the two members. The one-way check valve is disposed between the male and female members to prohibit fluid flow through the connector assembly in one direction when the male and female members are coupled together.Type: GrantFiled: January 4, 1995Date of Patent: January 21, 1997Assignee: Huron, Inc.Inventor: Lanny Brown

Patent number: 5411297Abstract: A quick connector assembly has a male fitting and a female fitting. The female fitting includes a conduit having a brazed eyelet which couples with a projection member including O rings on the male fitting to seal the male fitting with the female fitting. The female fitting includes a bracket placed at the other end of the conduit to secure the female fitting in place with respect to the male fitting. The fittings are able to enable axial and rotational movement with respect to one another.Type: GrantFiled: March 9, 1994Date of Patent: May 2, 1995Assignee: Huron, Inc.Inventor: Lanny D. Brown
