Filed:

Jul 23, 2010

Appl. No.:

12/842087

Inventors:

Christopher McAuliffe - Windsor CT, US
Jason Labrie - Westfield MA, US
Kevin Arthur Roberg - Norwich CT, US

Assignee:

Hamilton Sundstrand Corporation - Windsor Locks CT

International Classification:

E03B 3/18

US Classification:

137546, 137544, 251325, 55422

Abstract:

A control valve includes particle and moisture accumulation inhibiting features. The control valve includes a piston that provides for pressure communication to a back cavity through a tortuous path that settles out particle matter carried within the airflow. Moreover, the piston includes drainage openings that direct moisture out of piston and away from the sealing surfaces.

US Classification:

62211, 62225, 25112911, 251264, 236 92 B, 137 14

Abstract:

A refrigerant expansion valve for a refrigerant system includes a main body, a motor and first and second members. The main body has a refrigerant flow passage that extends therethrough. The first and second members are connected together and are configured with threads that have a different pitch to allow for relative movement between both members and the main body. The motor is positioned adjacent the main body and is coupled to the first member. The motor actuates the first member in response to control signals to move the second member within the main body to modulate the flow of refrigerant through the refrigerant flow passage.

Inventors:

Jason Labrie - Westfield MA, US

Assignee:

Hamilton Sundstrand Corporation - Windsor Locks CT

International Classification:

F16K 1/00

US Classification:

137 1, 251324

Abstract:

Disclosed is a poppet valve () including a housing () having an inlet port () and an outlet port (). A poppet () is located in the housing () and includes a poppet body () which blocks the outlet port () when the valve is in a closed position and a poppet tip () disposed at a distal end of the poppet body (). The poppet tip () includes at least one tip flow channel () extending substantially along a poppet axis () to meter flow therethrough as the valve () is moved from a closed position. A method of controlling a flow includes translating a poppet () located in a valve housing () in a first direction along a poppet axis (). At least one poppet flow channel () extends across a valve outlet port () via translation of the poppet (). A fluid is flowed from the inlet port () through a first flow area defined by the at least one poppet flow channel () extending across the outlet port ().

F16K 25/00

US Classification:

62529, 251318, 25112901, 251366

Abstract:

A poppet valve has a valve pin movable relative to a bore, and with a curved outside shape. A flow cross-sectional area across the poppet valve is defined between an outer diameter of the curved outside shape, and an inner diameter of the bore. Further, a vapor cycle incorporating such a poppet valve is disclosed and claimed.

International Classification:

F16K 5/00

US Classification:

251304

Abstract:

A valve includes a valve housing having an interior chamber and an actuator housing in which an actuator is disposed. The actuator housing is secured with the valve housing. A shaft is coupled with a valve member and the actuator and extends within a bore between the interior chamber of the valve housing and the actuator. The valve includes at least one vent passage that has a first end that opens to the bore and a second end that opens to an exterior of the valve housing and actuator housing.

International Classification:

F16K 1/00

US Classification:

251321

Abstract:

A pressure regulating valve controller includes a housing. A piston having a surface portion is arranged in the housing. A spring seat is arranged in the housing adjacent the piston. The spring seat includes a surface section. A diaphragm is arranged in the housing between the surface portion of the piston and the surface section of the spring seat. The diaphragm includes an opening. A diaphragm retention device is arranged in the opening of the diaphragm. The diaphragm retention device is configured and disposed to contact each of the surface portion of the piston and the surface section of the spring seat to reduce forces on the diaphragm.
