The system utilizes a fitting that, in one position, allows for normal function of the cooling system of a vehicle, and in another position the fitting allows for fluid exchange with an outside source, such as another vehicle. The outside source can be a second vehicle equipped with a fitting or a standalone heater. Fluid transfer hoses are connected to each fitting to exchange coolant between vehicles.Type: GrantFiled: October 31, 2014Date of Patent: April 4, 2017Assignee: ColdFire, Inc.Inventor: Dan Carter

Patent number: 9415151Abstract: This disclosure relates to blood flow reversal valves and related systems and methods. In certain aspects of the invention, a blood flow reversal valve includes a first member having a first passage and a second passage, and a second member having a first passage and a second passage. The first and second members are rotatably fixed relative to one another such that the first passage of the first member is aligned with the first passage of the second member and the second passage of the first member is aligned with the second passage of the second member. A flow directing element is disposed in the cavity and is moveable relative to the first and second members between a first position in which the first passage of the first member and the first passage of the second member are fluidly connected and a second position in which the first passage of the first member and the second passage of the second member are fluidly connected.Type: GrantFiled: March 5, 2013Date of Patent: August 16, 2016Assignees: Fresenius Medical Care Holdings, Inc., Fresenius Medical Care Deutschland GmbHInventors: Christian Schlaeper, Harald Peter, Martin Joseph Crnkovich

Publication number: 20150096314Abstract: A heat pump is provided including a plurality of lines having refrigerant flowing therethrough. A reversing valve is provided including a selector mechanism having a plurality of cavities formed therein and extending therethrough. A source of motion is coupled to the selector mechanism for movement of the selector mechanism. Each one of the plurality of cavities fluidly couples at least two of the plurality of lines. The selector mechanism is movable between a cooling mode and a heating mode so that the cavities fluidly couple different ones of the plurality of lines in each of the cooling mode and the heating mode. The selector mechanism will maintain its position with respect to the plurality of lines when the source of motion is de-energized, regardless of a pressure differential between different ones of the plurality of lines.Type: ApplicationFiled: September 29, 2014Publication date: April 9, 2015Inventors: Mark Shoemaker, Allen C.

Patent number: 8943801Abstract: A valve (10) may be used with an internal combustion engine exhaust breathing system (12) and may include a body (60), a partition (62), and a plate (66). The body (60) may define a first port (70) that has a first interior surface (76), and may also define a second port (82) that has a second interior surface (84). The partition (62) may be located within the body (60), may at least partially separate the first port (70) and the second port (82) from each other, and may define an opening (104). The plate (66) may be dimensioned to seat and seal against the opening (104) and against the first and second interior surfaces (76, 84). The plate (66) may rotate, depending on predetermined factors, between a first position and a second position.Type: GrantFiled: March 12, 2009Date of Patent: February 3, 2015Assignee: BorgWarner Inc.Inventor: Todd R.

Publication number: 20140311586Abstract: A control valve for hydraulic media is provided. The control valve includes a valve body having four ports. A first seat, a second seat, and a dual seat are positioned in the valve body between the ports. Two poppets, each including a disc and a cup, with a spring located therebetween, are arranged on a cylindrical pin with an enlarged engagement portion that is slidably supported within the valve body. A solenoid assembly movable in an axial direction within the valve body contacts the cylindrical pin and adjusts the position of the discs and cups of the poppets with respect to the seats of the valve body to minimize unwanted leakage between the ports. This configuration comprises four variable orifices that cooperate to provide controlled flow during different energizing phases of the solenoid assembly.Type: ApplicationFiled: March 25, 2014Publication date: October 23, 2014Applicant: Schaeffler Technologies GmbH & Co.
