US Patent:

6374624, Apr 23, 2002

Filed:

Mar 8, 2000

Appl. No.:

09/520083

Inventors:

Pandu Cholkeri - Worthington OH
William D. Kramer - Powell OH
Brian Enderle - Dublin OH

Assignee:

Ranco Incorporated - Plain City OH

International Classification:

F25B 4104

US Classification:

62222, 25112921

Abstract:

A refrigerant flow-control valve operable between a no-flow condition and a flow condition in response to a control signal supplied thereto. The flow-control valve includes a tubular-shaped body forming a refrigerant passageway extending from an inlet to an outlet, a cylindrically-shaped restrictor secured within the tube and forming a restriction, and a cylindrically-shaped stop secured within the tube and forming a plunger valve flow passage. The stop is located downstream and spaced-apart from the restrictor and the restriction has a greater resistance to flow than the valve flow passage. A plunger is within the tube between the restrictor and the stop and carries a valve element. The plunger is movable between a first position closing the valve flow passage to generally prevent refrigerant flow therethrough and through the passageway and a second position opening the valve flow passage to permit refrigerant flow therethrough and through the passageway. A compression spring is within the tube between the restrictor and the plunger and resiliently urging the valve element into the first position. A solenoid coil located about the tube adjacent the plunger is adapted to selectively move the valve element to the second position in response to a control signal supplied thereto.

Ranco Incorporated - Plain City OH

International Classification:

F25B 4106

US Classification:

62528

Abstract:

A refrigerant flow-control device is automatically operable between a normal or low-flow condition and a pressure relief or high-flow condition in response to pressure drop across the flow-control device, in one embodiment the flow-control device includes a tubular-shaped body having an inlet, an outlet, and a refrigerant passageway extending from the inlet to the outlet, a cylindrically-shaped restrictor secured within the tube and forming a second restriction, and a cylindrically-shaped collar secured within the tube and forming a poppet-valve flow passage. The collar is spaced-apart from the restrictor within the tube. A poppet is located within the tube partially between the restrictor and the collar and carries a valve element. The poppet is movable between a first position closing the poppet-valve flow passage to generally prevent refrigerant flow therethrough and a second position opening the poppet-valve flow passage to permit refrigerant flow therethrough. The poppet forms a first restriction.

Appl. No.:

09/997118

Inventors:

Allan McLane - Dublin OH
William D. Kramer - Powell OH

Assignee:

Ranco Incorporated of Delaware - Wilmington DE

International Classification:

F16K 11076

US Classification:

13762547, 13762516

Abstract:

A coolant flow valve for controlling the distribution and flow of coolant to replace the radiator thermostat and heater valve currently used in automotive applications. The valve includes a valve rotor rotationally received in a valve housing wherein the rotational orientation thereof determines which combination of flow paths through four different outlet ports is selected.

US Patent:

Filed:

Aug 11, 1980

Appl. No.:

6/177021

Inventors:

William D. Kramer - Powell OH
Ellis H. Born - Columbus OH

Assignee:

Abex Corporation - New York NY

International Classification:

F04B 4908

US Classification:

417217

Abstract:

A control for a variable displacement pressure compensated pump in which pressurized control fluid regulates the setting of a sequence valve to set the maximum output pressure of the pump and also set the displacement of the pump. The sequence valve is a two-stage device which utilizes a sequence poppet stage and cone stage. When working fluid pressure exceeds the setting of the sequence valve, the cone stage spills to reduce the displacement of the pump. If the pressure is not reduced fast enough the sequence poppet spills to more rapidly reduce the displacement of the pump.
