Definitions

  • the 35 17 002 A1 shows a water-cooled internal combustion engine in which the water pump is connected directly to the camshaft of the internal combustion engine and is driven by this.
  • the valve slide which is slidably mounted in the pump housing, has flow openings and an additional bypass connection opening into the slide working chamber0, is characterized in that a pressure ring disk is arranged on the slide rear wall of the valve slide, or the slide rear wall itself is designed as a pressure ring disk, and that this pressure ring disk is located on the pulley side opposite one / more contact surface (s) is / are arranged on the pump housing, and that one / more of these / outlet opening (s) surrounded by these contact surface (s) is / are arranged, which opens into the bypass nozzle, and that when the impeller outlet is fully released by the outer cylinder of the valve slide, the thrust washer is directly or indirectly in operative connection with the contact surface (s) on the pump housing and this closes the outlet opening (s).
  • the invention relates to a coolant pump for internal combustion engines that is mechanically driven by a belt pulley, a gearwheel, a stub shaft or the like and controllable by means of a valve slide.
  • WO 2018/158272 A1 shows a water pump which is arranged on the front side of the crankcase and is driven by a belt.
  • the object of the present invention is to avoid the aforementioned disadvantages and to create an internal combustion engine that has smaller construction dimensions, in particular in its linear expansion.
  • Fig. 1 Cylinder head with water pump, thermostat and connecting piece.
  • Fig. 2 Cylinder head with water pump housing, rotated view of Fig. 1.
  • Fig. 3 Cylinder head with thermostat from above.
  • Fig. 4 Section B-B from Fig. 3.
  • Fig. 5 Section C-C from Fig. 3.
  • Fig. 6 ModuM5 from Fig. 3.
  • the cylinder head 1 shown in FIG. 1 has a water pump 2 cast into the cylinder head 1; this water pump 2 has a thermostat 5 and a connecting piece 8.
  • the length, height and width of the motor are crucial in order to keep the devices in which this motor is to be installed compact.
  • One criterion for the engine length, width and height is the cylinder head 1 including the attachment of the water pump 2.
  • Today's constructions show consoles that are screwed in front of or on the cylinder crankcase and / or in front of or on the cylinder head 1. The consoles partially accommodate thermostats 5 and lines for the water supply to the water pump 2. These constructions require a sufficiently large installation space.
  • Other constructions show water pumps 2 in cylinder crankcases, which make the engine unusable wide in the area of the wheel lock in tractor applications.
  • FIG. 2 shows the rotated cylinder head with water pump housing from FIG. 1.
  • Fig. 3 shows the cylinder head 1 with thermostat 5 and module 15 from above.
  • the water pump 2 no longer determines the length of the engine.
  • the additional integration of the thermostat 5, as can be seen in Fig. 3, above the water pump 2 saves space in height and long distances of the water channels 7, which are an integral part of the common cast body, consisting of cylinder head 1 and water pump 2 are and saves additional piping, as shown in Fig. 4, to the water pump 2, since the water pump 2 is connected by means of water channel 7 directly to the cooling water volume of the cylinder head 1 through a channel in the cylinder crankcase.
  • FIG. 5 shows section CC from FIG. 3 with cylinder head 1, pressure channel 4, water pump worm 9 as parts of module 15.
  • the pressure channel 4 is directly connected to the water volume of the cylinder crankcase.
  • Fig. 6 the module 15 from FIGS. 3, 4 and 5 with impeller 10, to drive shaft with bearing 11 and housing cover 12 is shown.
