Definitions

  • the invention relates to an internal combustion engine with a Cylinder block, a cylinder head and a timing case cover, the timing case cover and the cylinder block Control housing as well as a pump inlet chamber and a Form the pump outlet chamber, which are separated from each other.
  • US-A-4,938,185 shows a timing case cover for one Internal combustion engine, with pump chambers in the timing case cover and connections of a coolant system are provided are in which they are molded into the timing case cover and which is formed essentially in one piece.
  • Coolant can penetrate into the control housing and there contaminate existing lubricant or the function of components arranged there can impair.
  • the timing case cover of the present invention provides one Cover for a valve control available.
  • the Valve control is arranged in a control housing, which through the front surface of the cylinder block and the Control housing cover is formed.
  • the timing case cover can also be provided with molded connections in order the timing case cover with a radiator or a Connect heat exchanger to coolant to the heat exchanger as well as leading away from this.
  • the timing case cover forms a pump inlet chamber which communicates with the coolant inlet may be connected to coolant from the heat exchanger received, as well as a coolant outlet chamber, which Coolant can be supplied from a coolant pump.
  • the Pump outlet chamber can have a coolant inlet in the Connect cylinder block to coolant to the To direct cylinder block.
  • the coolant flows in a known manner and way through the cylinder block and to a cylinder head and is from the cylinder head into a chamber for receiving hot coolant, which is also in the Control housing cover can be molded.
  • a chamber stands with a coolant outlet in the timing case cover in Connection to deliver the coolant to the heat exchanger.
  • This coolant outlet can house a thermostat.
  • the timing case cover can be screwed to the cylinder block and does not have to be screwed to the cylinder head. Accordingly, it is possible to have a flexible seal between the cylinder head and the timing case cover to provide ensure a tight connection.
  • the control housing cover can also one Bypass channel from the chamber to receive hot coolant to the pump inlet chamber to maintain a coolant flow through the internal combustion engine before the Thermostat opens.
  • FIG. 1 a front area of a Internal combustion engine 10 shown.
  • the internal combustion engine 10 it is an in-line engine with several cylinders. It the front surface 12 of a cylinder block 14 as well as the Front surface 16 of a cylinder head 18 shown.
  • the terms “Front” and “rear” are for illustrative purposes only used and are not to be understood as restrictions.
  • It also becomes a timing case cover 20 and a coolant pump 22 shown.
  • the timing case cover 20 is on the cylinder block 14 attached by a plurality of screws 24, which are through openings 26 in the control housing cover 20 and in with Threaded openings 28 in the cylinder block 14 extend.
  • the coolant pump 22 has a pump housing 30 on the timing case cover 20 through some of the Screws 24 is held, which through openings 32 in the Pump housing 30 and through the openings 26 in the Timing case cover 20 and into the threaded Extend openings 28 in the cylinder block 14.
  • the control housing cover 20 is shown in both FIG. 1 and FIG Fig. 2 shown.
  • the control housing cover 20 is approximately pan-shaped and has a front wall 36 and protruding Side walls 38 on. Additional projecting partitions 40, 42 and 44 are provided inside the timing case cover 20 to create various chambers as described below form.
  • the protruding side walls 38, as well as the protruding partitions 40, 42, 44 all form one Inner surface 46 of the timing case cover 20.
  • This inner surface 46 engages on the front surface 12 of the cylinder block 14.
  • Between the inner surface 46 and the front surface 12 is one Seal (not shown) provided to interpose a To form a seal.
  • the crankshaft extends through openings 48 in the Timing Cover 20.
  • An oil pump (not shown) is in a round eye 50 is arranged which surrounds the opening 48.
  • An inlet of the oil pump is shown at 52.
  • the control housing cover 20 is fixed with a coolant inlet 54 connected to a hose to connect coolant to get from a heat exchanger.
  • the timing case cover 20 is also firmly connected to a coolant outlet 56.
  • the Coolant outlet 56 also serves as a thermostat housing and represents a connection with a heat exchanger hose, which coolant from the engine 10 to the Heat exchanger supplies.
  • the coolant inlet 54 directs coolant into one Pump inlet chamber 58, which by the protruding Partitions 40, 42 as well as from the front wall 36 and Front surface 12 of the cylinder block 14 is determined.
  • coolant flows from the pump inlet chamber 58 through an opening 60 in the coolant pump, which is on the opposite side of the Front wall 36 is attached.
  • the coolant pump does that Coolant back through an opening 62 in the front wall 36 and into a pump outlet chamber 64.
  • the pump outlet chamber 64 becomes through the protruding partition 42 as well as through the protruding side wall 38 together with the front wall 36 and the Front surface 12 formed. Coolant flows from the Pump outlet chamber 64 through opening 66 in the front 12 of the cylinder block 14 in the cylinder block 14. Das Coolant then flows through the in a conventional manner Cylinder block 14 to the cylinder and up in the Cylinder head 18.
  • Coolant flows from the cylinder head 18 through the opening 68 and into a chamber 68 in the timing case cover 20 which contains hot coolant. This flows from this chamber 68 Coolant through the coolant outlet 56 to which not Thermostats shown past and back into the heat exchanger.
  • An elastic seal 70 is on the timing case cover 20 in a sealing groove that defines the opening in chamber 68 surrounds, attached.
  • the elastic seal 70 is off Made of rubber or a synthetic material, which in is able to withstand high coolant temperatures without decomposition resist.
  • the elastic seal 70 is required because of the Control housing cover 20 only screwed onto the cylinder block 14 and is not screwed to the cylinder head 18.
  • a coolant bypass channel 72 is in the wall between the Chamber 68 and the pump inlet chamber 58 formed. This Bypass channel 72 allows coolant to flow through the Internal combustion engine 10 to circulate when the thermostat closed is.
  • the control housing cover 20 has a control housing 74, which essentially consists of the projecting side walls 38 and the protruding partition 40 is determined.
  • the Control housing 74 communicates with the lubricating oil Internal combustion engine, which is used to a Lubricate valve timing and a valve timing chain.
  • the Control housing cover 20 is designed such that the Low pressure pump inlet chamber 58 the high pressure pump inlet chamber 64 completely from the control housing 74 separates. Consequently, any coolant that comes from the Pump outlet chamber 64 escapes into pump inlet chamber 58 get instead of flowing into the control housing 74, where that Coolant would contaminate the lubricating oil.
  • the arrangement of the Coolant chambers 58, 64 within the control housing 74 improves the reliability of the engine 10 by the possibility of coolant escaping into the Lubricating oil is reduced or excluded.
  • the pump housing 30 has a drain port 76 to it to allow coolant from the cylinder block 14 and Lower the cylinder head 18.
  • a drain port 76 to it to allow coolant from the cylinder block 14 and Lower the cylinder head 18.
  • the coolant pump 22 is shown in more detail in FIG. 3 shown.
  • the coolant pump 22 has an impeller 78 a plurality of wings 80.
  • the impeller 78 rotates in Clockwise, as shown in Fig. 3, around the coolant from the impeller 78 and through a chamber 82 in the Pump housing 30 to move.
  • the coolant then flows through the opening 68 in the timing case cover 20 in the Pump outlet chamber 64.
  • the control housing cover 20 provides an integral, one-piece Arrangement available that covers both the inlet and the Exhaust port forms to coolant to and away from the To let internal combustion engine 10 flow.
  • the Coolant path through the control housing cover 20 to achieve of high reliability by the Pump outlet chamber 64 is isolated from the control housing 74.
