Patent number: 7146819Abstract: The invention relates to a method of refrigerant level monitoring in a refrigerant circuit of an air-conditioning or heat-pump system having a compressor and a refrigerant which may, depending on the operating point, be operated in the supercritical range. The method includes standstill level monitoring with the compressor switched off and/or in-operation level monitoring with the compressor switched on. In the case of in-operation level monitoring, the refrigerant overheat (dTü) at the evaporator is registered and, in the event of excessive overheat, it is concluded that there is underfilling. At a standstill, the pressure and temperature of the refrigerant are registered, and it is concluded that there is an improper refrigerant filling level if the pressure (pKM) lies below a minimum pressure value (pmin) or the temperature (TKM) lies above a maximum saturation temperature value (TS) with the pressure being outside a predefinable intended pressure range ([pu,po]).Type: GrantFiled: February 10, 2004Date of Patent: December 12, 2006Assignee: BEHR GmbH & Co.Inventors: Walter Demuth, Rainer Heilig, Volker Kirschner, Martin Kotsch, Hans-Joachim Krauss, Hagen Mittelstrass, Harald Raiser, Michael Sickelmann, Karl-Heinz Staffa, Christoph Walter

Patent number: 6953325Abstract: A safety device limits the pressure in an axial-piston compressor with variable piston displacement. The compressor has as wobble plate or swash plate whose tilt angle can be variably controlled by the pressure differential between the high pressure in the discharge pressure zone and the pressure in the piston-drive chamber. The safety device consists of a valve arranged in a connector channel between the discharge pressure zone and the pressure zone of the piston-drive chamber. When the discharge pressure exceeds a given pressure limit, the safety device responds by allowing an increased flow of pressure medium from the discharge pressure zone to the piston-drive chamber. The influx of pressure medium into the piston-drive chamber causes a reduction of the tilt angle of the swash plate or wobble plate.Type: GrantFiled: January 6, 2003Date of Patent: October 11, 2005Assignees: LuK Fahrzeug-Hydraulik GmbH & Co., KG, Behr GmbH & Co.Inventors: Georg Weber, Michael Sickelmann, Tilo Schäfer, Christoph Walter, Hans-Joachim Krauss, Harald Raiser, Frank Obrist

Patent number: 6772518Abstract: The invention relates to a method for forming at least one flat-tube insertion slot in a header tube. A sawcut is introduced into the header tube during a sawing step, and the slot is configured, during a subsequent punching step, by means of a slot punch, which punches into the region of the sawcut. A rimmed opening can be configured during the punching step by using a slot punch with a larger width and/or length relative to the sawcut. The sawcut is preferably introduced to a depth less that the wall thickness of the header tube. The respective web region(s) between chamber of a multi-chamber header tube can be compressed during the punching operation to a level lower than that of a header-tube wall region functioning as a flat-tube insertion stop, in order to form a chamber-connecting duct.Type: GrantFiled: January 22, 2002Date of Patent: August 10, 2004Assignee: Behr GmbH & Co.Inventors: Walter Demuth, Wolfgang Geiger, Martin Kotsch, Hans-Joachim Krauss, Hagen Mittelstrass, Harald Raiser, Michael Sickelmann, Karl-Heinz Staffa, Christoph Walter
