Patent number: 7063511Abstract: An integrated capacity control valve for a variable capacity refrigerant compressor includes an integral pressure sensor that is continuously coupled to a discharge port of the valve for measuring the refrigerant discharge pressure. A plunger of the control valve is disposed within a passage coupling the compressor crankcase to the discharge port, and is positioned by pneumatic and electric control elements to regulate the refrigerant suction pressure. The plunger has intersecting axial and lateral bores that define a continuous passage between the discharge port and a cavity in which the pressure sensor is retained so that the sensor is continuously exposed to the discharge pressure regardless of the plunger position, and refrigerant discharge pressure in the lateral bore produces a bias force on the plunger that compensates the pneumatic suction pressure setpoint for a pressure drop between the evaporator and the suction port of the valve.Type: GrantFiled: July 28, 2003Date of Patent: June 20, 2006Assignee: Delphi Technologies, Inc.Inventors: Thomas Martin Urbank, Karma Vir Sangwan, Ernesto Jose Gutierrez

Patent number: 7062966Abstract: A small profile fuel level sensor has a small float located in a vertically-oriented housing in a fuel tank, and instead of sliding against two resistive strips that output a level signal as fuel level changes, the float is drawn to and rolls against the two strips owing to the presence of a magnetic strip on the side of the resistive strips that is opposite the float. Accordingly, with the magnetic strip attracting the float against the resistive strips to force rollable contact therebetween instead of slidable contact, much less friction must be overcome to move the float and, hence, use of a relatively small float and overall small sensor assembly is facilitated.Type: GrantFiled: February 3, 2005Date of Patent: June 20, 2006Assignee: Delphi Technologies, Inc.Inventor: Gabriel Davila
