Definitions

  • the invention relates to a water pump for a Cooling circuit of an internal combustion engine according to the generic term of claim 1.
  • cooling circuit of an internal combustion engine commonly known to use a water pump, being control via thermostats, which is temperature-dependent switch the cooling circuit.
  • the drive the water pump can be operated mechanically via one of the Internal combustion engine driven belt drive or can also be done electrically.
  • To switch the Coolant flows and the heating circuit are Cycle valves, slide and rotary valves with stepper motor drives known from practice.
  • DE 43 24 749 A1 is a control valve for one Cooling circuit described, with a radial inlet and three radial outlets, the distribution of the Coolant is done by a rotary valve.
  • a disadvantage of this control valve is that always has resulting forces on the rotary valve, which can lead to deadlocks and / or accordingly strong drive motors for its adjustment make necessary. In addition, the adjustment or Mixed positions limited.
  • DE 44 38 552 C1 is a temperature control device for the cooling circuit of an internal combustion engine described, which with actuators for a switching flap arranged on a selector shaft is provided.
  • the control valve shaft is in the Area of an imaginary wall line of the radiator return line or pump feed and in the confluence area the short-circuit line into the pump supply line.
  • the switching flap is a thermal expansion element, a so-called wax cartridge.
  • the present invention is based on the object a control device for the cooling circuit To create internal combustion engine, which in a very compact design of several sections of the cooling circuit and several functions of actuating and switching elements includes.
  • control valve in the housing of the water pump is a very compact Component reached, at the same time by the Control valve with a corresponding design several Switch positions are realizable, so that if necessary further control elements in a cooling and if necessary a heating circuit of an internal combustion engine can be omitted. Not only that various functions or switching positions but also the mechanical parts necessary for control be added to the pump housing or accordingly be flanged to the pump housing.
  • control valve as a rotary valve with the axial feed or Removal of the cooling medium and the inlet or outlet openings there are none on the circumference of the pump housing resulting forces on the rotary valve, so that one with low positioning and holding forces for the rotary valve gets along.
  • Control valve only slight pressure losses on, with high positioning speeds at the same time.
  • the axial opening in the rotary valve serves for feeding of coolant in its interior when the Rotary valve on the pressure side of the pump device is arranged, in which case that in the peripheral wall of the pump housing arranged openings Outlet openings for the transmission of the cooling medium represent.
  • a simple thermal expansion element e.g. a wax cartridge
  • One becomes a rotary valve in the peripheral wall of the pump housing provide only two sub-circuits, namely one for the cooler line and the second sub-circuit for the short circuit of the cooling water during the warm-up phase.
  • a servomotor for the rotary valve can also have several sub-circuits with corresponding Inlet or outlet openings in the peripheral wall of the Pump housing may be provided.
  • a possible design consists in that in addition to the partial circuit another sub-circuit for the cooler line for a short circuit circuit line and a third Partial circuit for a heat exchanger of a heating circuit are provided.
  • a partial circuit can also be used for an additional heater and / or an exhaust gas heat exchanger be provided.
  • the water pump shown in the figures is fundamental of known design, which is why only below on the parts essential to the invention is received.
  • the water pump as Pump device one arranged in a pump housing 1 Centrifugal pump with one in a spiral channel 2 arranged impeller 3 be.
  • the impeller 3 is in known manner driven by a drive motor 4.
  • the drive via the drive motor 4 is also a mechanical drive via one of the Belt drive driven by an internal combustion engine, e.g. With a V-belt, conceivable for the water pump.
  • a control valve 5 arranged with a rotary valve 6 in the form of a sleeve, the longitudinal axis of the rotary valve coaxial with Longitudinal pump axis or the impeller 3 is.
  • a axial collecting opening 7 of the rotary valve 6 forms a Inlet opening to the impeller 3 of the water pump.
  • cooler line 8 opens into the with an inlet opening 9 Circumferential wall of the pump housing 1.
  • the Circumferential wall of the pump housing 1 also with provided two further inlet openings 10 and 11, the for further partial circuits of the cooling medium in the Cooling circuit are provided.
  • the rotary valve 6 Completed on the front and on this side too with an actuator 12 for rotating the rotary valve Mistake.
  • the rotary valve 6 is in its peripheral wall with a Control opening 13 provided. Via the control opening 13 takes place depending on the rotary position of the rotary valve 6 a connection from the inlet opening 9, 10 or 11 to the collecting opening 7 and thus a connection to the suction side of the impeller 3 of the water pump.
  • Fig. 3 the angles are by means of a sectional view represented by the center plane of the connection cross-sections. All angles are directly related with the cross-sectional functions. In addition to the relatively simple form of a hole for the openings you can also choose other, non-circular cross-sections become. That way you can get another one Degree of freedom in determining the actuating behavior to reach.
  • connection piece radially from the pump housing 1.
  • the connecting piece semi-axially or against to apply the radial inclined to the pump housing 1.
  • FIGS. 4 shows the position in normal operation 5 shows a first mixed operation in the warm-up phase of the engine with simultaneous heating operation, the inlet opening 9 of the cooler line being shut off and the inlet openings 10 and 11 being open for the short-circuit circuit line and for the heating circuit.
  • FIG. 6 shows one second mixed operation in the phase Warm up “and Cooling ", whereby the heating circuit is shut off.
  • Short circuit e.g. for the cylinder head be.
  • the rotary valve 6 can do any circuit switch separately. You can also choose between each two circuits set any mixing levels be.
  • control valve 5 also with only two inlet or outlet openings provided in the peripheral wall of the pump housing 1 be. In this case, one becomes the circumferential openings for the cooler line and the short circuit circuit line provide.
  • a servomotor 12 is sufficient then for changing the angle of rotation of the rotary valve 6 a simple wax cartridge.
  • the rotary valve 6 with a bimetal strip to be provided as an adjustment device.
  • a peripheral opening can also be used as a partial circuit for an additional heater or an exhaust gas heat exchanger is provided be. Also combinations of different sub-circuits are self-evident in the context of the invention possible.
  • an electronic one Interface can be a central connection for data exchange, for setpoint specifications and for serve a further exchange of information.
  • the two interfaces in one Housing 14 sit, which to the pump housing 1 and the Drive motor 4 is flanged.
  • control valve By integrating the control valve into the pump housing 1 offers the possibility of the flow all important partial flows in a cooling circuit switch. Through the integration is still a compact, cost-saving and reliable design a central working and control element for vehicle repair possible. A regulatory body for the speed of the water pump is thus around the control function extended for the control valve 5.
