Publication number: 20140262135Abstract: The invention relates to valve system configurations for an active warm-up (AWU) system for an automobile to improve warm-up conditions without delaying cabin warm-up or defrost times. More specifically, the invention relates to a system for heating/cooling transmission fluid of an automobile by controlling the source of the heat exchange fluid for transferring heat to/from the transmission fluid during different start-up conditions using a series of various valves arranged in series intermediate a first heat exchanger associated with cabin warm-up/defrost of the passenger compartment and a second heat exchanger for transferring heat to/from the transmission fluid.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Inventors: Jeff Sheppard, Dario Bettio, Sachin Bhatia

Publication number: 20130319634Abstract: The invention relates to various ways in which to integrate control valves into the structure of a heat exchanger. Accordingly, there is provided a heat exchanger assembly comprising a heat exchanger and a valve integration unit. The heat exchanger includes a plurality of alternating first and second fluid passages in heat exchange relation, and at least one inlet manifold and one outlet manifold interconnected by one of the plurality of first or second fluid passages, the valve integration unit being fixedly attached to heat exchanger and comprising a fluid passage in fluid communication with at least one of the inlet and outlet manifolds. A valve mechanism is mounted within the valve integration unit in fluid communication with the fluid passage, the valve mechanism controlling the flow of a heat exchange fluid through said fluid passage.Type: ApplicationFiled: May 30, 2013Publication date: December 5, 2013Inventors: Jeff Sheppard, Dario Bettio, Sachin Bhatia

Patent number: 8539983Abstract: A by-pass valve for a heat exchanger circuit. The by-pass valve includes a housing defining a serially communicating first bore, second bore and third bore substantially aligned along a central axis with a valve seat facing the first bore at a juncture between the first bore and second bore and a spring seat facing the second bore at a juncture between the second bore and third bore, the first bore, second bore and third bore forming at least a portion of a closable flow path between a first opening and a second opening in the housing. An actuator located in the housing has a reciprocating seal disposed for movement along the central axis for engaging the valve seat and closing a valve opening between the first bore and second bore. A coiled return spring is mounted in the housing for urging the reciprocating seal towards the first bore to open the valve opening, the return spring having a first end acting on the reciprocating seal and a second end engaging the spring seat.Type: GrantFiled: January 28, 2011Date of Patent: September 24, 2013Assignee: Dana Canada CorporationInventors: Mark Stephen Kozdras, Jeff Sheppard, Dario Bettio

Publication number: 20120161042Abstract: A valve apparatus having a first housing coupled to a second housing. The first housing having a first chamber in fluid communication with a first inlet and a first outlet. The first chamber adapted for receiving a thermal actuator moveable from a first position to a second position in response to temperature of a first fluid in the first chamber. The second housing having a second chamber in fluid communication with a first and a second ports, the second chamber being fluidly sealed from the first chamber. The second chamber adapted for receiving a valve mechanism, which is operatively coupled to the thermal actuator and moveable from a first valve position preventing flow of a second fluid from the first port to the second port to a second valve position permitting flow of the second fluid from the first port to the second port upon actuation by the thermal actuator.Type: ApplicationFiled: December 19, 2011Publication date: June 28, 2012Applicant: Dana Canada CorporationInventors: Jeff Sheppard, Dario Bettio, Sachin Bhatia

Patent number: 8083209Abstract: A valve that includes a housing defining first and second bores having a central axis, and a peripheral valve seat. An actuator is located in the first bore and has a reciprocating seal disposed for movement along the central axis for engaging the valve seat and closing the valve. A coiled return spring is mounted in the housing for urging the reciprocating seal towards the chamber to open the valve, the return spring having a first end connected to the reciprocating seal and a second end engaging a spring support in the housing facing the first bore. The return spring may have a larger diameter at its second end than its first end. The housing may include a third bore in communication with the second bore and having a different cross-sectional area than the second bore. The return spring could be supported by a discrete spring support located in one of the bores.Type: GrantFiled: April 23, 2009Date of Patent: December 27, 2011Assignee: Dana Canada CorporationInventors: Mark Stephen Kozdras, Jeff Sheppard, Robert Arundine, Silvio Tonellato, Dario Bettio
