Publication number: 20210131334Abstract: A fluid actuated normally closed coolant control valve. The valve comprises a valve housing, an inlet port, the inlet port configured for fluid communication with either a coolant source or a heat exchanger of a DEF tank; an outlet port configured for fluid communication with the other of the heat exchanger of a DEF tank or the coolant source; a valve chamber, a valve and an actuator configured to actuate the valve. The actuator is a fluid actuated piston. The valve is biased to a closed condition in which the flow of coolant from the inlet port to the outlet port is prevented by the valve. The valve is actuatable to an open condition in which the flow of coolant from the inlet port to the outlet port is permitted, and the valve is withdrawn from the valve chamber, wherein the flow factor for the valve is greater than 1.5.Type: ApplicationFiled: November 5, 2019Publication date: May 6, 2021Applicant: Norgren GT Development CorporationInventors: Charles E.

Patent number: 8074684Abstract: The present invention relates to a leveling valve including a first port, a second port, a third port, a valve, and a clutch. The clutch is provided with an engaged position and a disengaged position. At least a portion of the clutch may move relative to the valve when the clutch is in the disengaged position. The clutch moves the valve when the clutch is in the engaged position. The valve is movable between a first position, a second position, and a third position. When the valve is in the first position, the valve blocks a first pathway, which extends from the first port, from connecting with a second pathway, which extends from the second port. When the valve is in the second position, the valve allows the first pathway to connect with the second pathway. When the valve is in the third position, the valve allows the second pathway to connect with a third pathway, which extends from the third port.Type: GrantFiled: October 12, 2007Date of Patent: December 13, 2011Assignee: Norgren GT Development CorporationInventors: Charles Stephens, John Michael Morris
