Definitions

  • the invention relates to a pressure control and holding valve arrangement according to the Preamble of claim 1.
  • Such an arrangement is known, for example, from DE 30 24 209 A1 for liquid cooling for internal combustion engines, wherein a preferably electronic control device is provided for regulating the coolant circulation, which controls the adjustment of the shut-off element or the like depending on a comparison of an actual value determined by the engine temperature with an adjustable setpoint controls.
  • a motor or electromagnetically operated valve or the like which interacts with the control device serves as a shut-off device. No reference to the formation of such a shut-off element can be found in the publication.
  • the object of the invention is therefore a pressure control and holding valve arrangement to design the specified type, in particular a functionally reliable Operation is available and can be produced inexpensively.
  • Fig. 1 shows schematically an inventive pressure control and holding valve arrangement 1 in connection with a coolant pump 2 and a Coolant circuit 3, in particular for an engine 4, its operating temperature detected by a temperature sensor 5 and possibly as a function from further operating signals to control signals for one shown in FIG Pressure control and holding valve 6 is processed, the valve closing body 7, which with a between a line section 8, in which the coolant pressure to be regulated prevails, and a line section 9 a return connection 11 leading into a suction connection 10 of the pump 2 arranged valve seat 12 cooperates.
  • valve closing body 7 is connected to a diaphragm 13 which on the one hand delimits a diaphragm chamber 14 which is directly connected to a pressure connection 16 of the pump 2 via a connecting line 15 and on the other hand delimits a control pressure chamber 17, which can be connected to the diaphragm chamber 14 via a control valve 18 and to the pressure connection 16 of the pump 2 via the connecting line 15 and, moreover, is connected to the return connection 11 via a connecting line 19.
  • the connecting line 19 can be arranged directly in the valve closing body 7 (solid line) or can be designed as a separate line 19 (chain line). With this arrangement, the operating temperature of the engine can be controlled sensitively.
  • the membrane 13 is kept constant at one value, specifically by that simultaneously with the pressure drop in the control pressure chamber 17 Pressure drop in the membrane chamber 14 takes place, the measure is provided for this, that the membrane chamber 14 via a connecting line 21 the return port 11 is connected.
  • control valve 18 as Solenoid valve 24 is executed and responds to electrical control signals.
  • These can be provided by an electronic control unit in which the specified sensor signals are processed.
  • a cooler 26 is used, the heat in the free environment.
  • a connecting line 27 is arranged, in which a cooler 28 is inserted is that gives off the heat to the passenger compartment when the engine running.
  • the arrangement according to the invention can thus be produced inexpensively.
