Patent number: 6686748Abstract: Arrangement to test HF tightness of a junction between two adjacent parts including HF generator (4), HF line that guides the signal over junction (1), measuring device (10) as well as a signal analyzer. HF line includes two waveguides (5a, 5b) that have inner conductors (6a, 6b) connected all the way through by a connection conductor (9) and outer conductors (7a, 7b) interrupted and each connected with electrodes (8a, 8b). A capacitive coupling of the HF signal occurs on one side of the junction and a capacitive decoupling of the HF signal takes place on the other side. By comparing the measured transmission and/or reflection of the HF signal with a transmission or reflection characteristic for the junction, it can be determined if the junction is HF tight. This makes it possible to test HF shielded cases for HF tightness in a non-destructive manner and without interfering with the contents.Type: GrantFiled: April 4, 2002Date of Patent: February 3, 2004Assignee: Schroff GmbHInventors: Peter Reiser, Robert Benko, Hans Martin Schwenk

Patent number: 5806479Abstract: A cooling system of an internal combustion engine of a motor vehicle has a cooling circuit, including a coolant/air radiator for cooling the engine, and a heating circuit, including a coolant/air heat exchanger for heating the passenger compartment. The cooling system includes an additional or secondary heater integrally associated with a coolant/air radiator to increase the heating capacity. The problem encountered with modern engines, particularly diesel engines, is that too little heat is available for heating the passenger compartment. Consequently, a secondary heater is needed. The secondary heater, which can be a fuel heater with a burner part and a heat exchanger part, is integrated into the radiator. This arrangement is advantageous in that the burner, with its fuel and exhaust gas line, is located outside the passenger compartment.Type: GrantFiled: April 4, 1997Date of Patent: September 15, 1998Assignees: Behr GmbH & Co., J. Eberspaecher GmbH & Co.Inventors: Dieter Bauer, Michael Humburg, Michael Loehle, Wolfgang Pfister, Peter Reiser, Gebhard Schweizer

Patent number: 5732880Abstract: The vehicle heater described has a burner supplied from a tank through a fuel line to which a pressure-controlled fuel pump (2) and a solenoid valve (24) are connected. The solenoid valve offers a relatively high resistance to the flow of fuel. The pressure in the pump delivery line thus drops relatively slowly. If vapor/gas forms in the fuel line (L2, L3, L4) due to overheating, it must be driven out of the line as rapidly as possible when the heater is switched on. The solenoid valve (24) offers only a low resistance to air/vapor/gas, resulting in a rapid drop in pressure at the pump delivery outlet and hence an increase in pump frequency (i.e. pump performance). The gas is therefore driven very rapidly out of the line between the pump and the burner, thus avoiding any interruptions in operations due to gas/vapor which has collected in the fuel line.Type: GrantFiled: February 6, 1997Date of Patent: March 31, 1998Assignee: J. Eberspacher GmbH & Co.Inventors: Herbert Langen, Peter Reiser, Dirk Brenner, Wolfgang Pfister, Walter Blaschke, Erwin Burner

Patent number: 5194718Abstract: A method for providing uniform thermal output from a glow plug for use in an auxiliary heater of a motor vehicle having either a 12 volt or 24 volt power supply without the use of multiplier resistors utilizes a glow plug having two heating rods having the same electrical resistance and three electrical terminals. One end of the first and second rods are permanently electrically connected respectively to the first and third terminals and the other end of the first and second rods are permanently electrically connected to the second terminal. The vehicle voltage is determined and if the 12 volt supply is present the first and second terminals are connected to the power supply and the first and third terminals are electrically connected to each other to place the heating rods in parallel. If a 24 volt supply is present, the first and third terminals are connected to the power supply with the second terminal left in connected thereby placing the heating rods in series.Type: GrantFiled: July 24, 1990Date of Patent: March 16, 1993Assignee: J.

Patent number: 5097813Abstract: A heating device for pre-heating liquid fuel, especially diesel fuel and for heating devices of a low heating performance which are independent from a motor have a heating performance which is suitable for mounting into vehicles, which are driven by the liquid fuel. The pre-heating is effected by a transmission of heat of the exhaust gas to the fuel of the heating device, the fuel being lead through a continuous tubular wrapping in one layer or through a hollow cylinder formed or positioned around the exhaust pipe. This wrapping or hollow cylinder is part of the fuel main from the fuel tank to the fuel supply pump of the heating device. A pre-heating of the content of the tank is effected by the return of the pre-heated, but not burnt fuel through a fuel return main back into the tank. A heat transmitting jacket is advantageously disposed between the wrapping, or a hollow cylinder and the exhaust gas pipe.Type: GrantFiled: November 21, 1990Date of Patent: March 24, 1992Assignee: J. EberspacherInventors: Peter Reiser, Fritz Mohring, Adolf Schodt

Patent number: 5078317Abstract: In space heaters with pressure atomization burners, which have a small combustion chamber volume, good mixing of air with fuel is achieved practically only in the case of relatively high air flow velocities, which leads, however, to difficulties in terms of ignition, especially at high operating voltages and low temperatures. The blower motor is therefore started first when putting the heater into operation, after which it is disconnected from the power source, so that the speed will again decrease, after which the high-voltage ignition and the fuel supply are turned on, so that the ignition can take place at reduced blower speed, and the high-voltage ignition is turned off and the blower motor is restarted after the flame has been recognized in the burner.Type: GrantFiled: February 22, 1990Date of Patent: January 7, 1992Assignee: EberspacherInventors: Erich Kenner, Peter Reiser, Gerhard Gaysert

Patent number: 4984736Abstract: By temperature gradient detection it is determined for the liquid combustion chamber auxiliary heater for motor vehicles, whether e.g. a flame blow-off has taken place, which has to be interpreted as a malfunction and hwich necessitates the discontinuation of fuel supply. Alternatively, it might merely show the switching from a high setting to a low setting. In the latter case a temperature drop to a lower operation temperature occurs also. However, the temperature drop is not as steep as in the case of a flame blow-off. At certain points in time t.sub.1 the target temperature for a point in time t.sub.2 is calculated by the detected temperature according to a certain algorithm having specific device properties as parameters. At this point in time the calculated target temperature is checked for errors.Type: GrantFiled: June 9, 1989Date of Patent: January 15, 1991Assignee: J.

Patent number: 4931011Abstract: Formerly unpleasant blue smoke was generated in a vaporizer burner for auxiliary heaters for motor vehicles once the fuel supply was cut off and the flame died down, as the remaining fuel was merely heated up, but not burnt. According to the invention the glow plug is activated for a determined period of time during the after-running phase of the combustion air blower. By this means practically all remaining fuel is vaporized and burnt and therefore the forming of blue smoke and remaining residues in the area of the plug muff and/or the burner is avoided.Type: GrantFiled: March 10, 1989Date of Patent: June 5, 1990Assignee: J. EberspacherInventors: Peter Reiser, Erich Kenner
