Definitions

  • the invention relates to a control valve for the coolant circuit of an internal combustion engine, in particular a motor vehicle, which regulates the distribution of the coolant flow from an outlet to an inlet of the internal combustion engine to a cooler arranged between the outlet and the inlet and to a short-circuit line bypassing the cooler and the one has arranged in the coolant flow valve carrier, which is provided with two axially spaced valve plates attached to it, which are assigned to two opposing valve seats and which each control, together with the associated valve seats, the connection of a valve chamber to the radiator and to the short-circuit line.
  • a thermostatic valve which contains a thermostatic working element is usually provided in the coolant circuit of the internal combustion engines of motor vehicles.
  • the housing of the thermostatic working element containing a temperature-dependent expanding material is provided with two valve plates, one of which is assigned to the short-circuit line and the other to the connecting line to the cooler.
  • a piston is arranged in the housing of the thermostatic working element and bears against a stationary abutment.
  • the housing of the thermostatic working element is arranged in the coolant flow. If the coolant exceeds a specified temperature, the working piston extends from the housing and moves the housing together with the valve disks.
  • such a thermostatic valve has a predetermined valve characteristic.
  • the invention has for its object to provide a control valve for the cooling water circuit of an internal combustion engine, which is simple in construction and uses as many of the elements which have been tried and tested in practice, and which enables a quick response to a large number of influencing variables.
  • valve carrier is rigidly connected to an adjusting element which is led outward from the area of the coolant flow and which is attacked by a drive element of an actuator.
  • control valve the structure of which essentially corresponds to the structure of a conventional thermostatic valve, but without a thermostatic working element being provided.
  • the valve carrier replacing the thermostatic working element is rather rigidly connected to an adjusting element and is adjusted directly via an actuator.
  • the actuator can or the like depending on various influences of the engine control or engine load. can be controlled, whereby a very rapid adjustment of the control valve can be carried out, i.e. very fast control games are possible.
  • a basic redesign of the coolant circuit and the control valve arranged therein is not necessary, since essentially the construction according to the conventional thermostatic valves is realized in the control valve according to the invention. It is therefore also readily possible to install such a control valve in already existing units in order to be able to control them in particular in order to achieve improved combustion.
  • the drawing shows a section through a control valve according to the invention.
  • control valve according to the invention of the drawing shown is explained using the example of a so-called distribution control. However, it is readily apparent to the person skilled in the art that the same control valve can also be used in a so-called mixed control, in which the structure of the control valve is then identical, while only the directions of the coolant flow have been slightly changed.
  • a distribution chamber 22 is provided in a housing 17, into which a channel 21 opens, which with the outlet of the cooling water management of an internal combustion engine, not shown, is connected.
  • a branch 13 branches off from the distribution chamber 22 and leads directly via a short-circuit line (not shown) back to the inlet of the cooling water duct of the internal combustion engine.
  • the distribution chamber 22 is covered by a housing part 8, which is provided with a connecting piece 9, to which a connecting line leading to a cooler, not shown, is connected, the outlet of which is in turn connected to the inlet of the cooling water duct of the internal combustion engine, not shown. Both the channel 13 and the connecting piece 9 are each assigned a valve.
  • the valve belonging to the connecting piece 9 is formed from a valve plate 5 and a conical valve seat 16 of the housing part 8.
  • the valve assigned to the channel 13 consists of a valve plate 6 and the mouth of this channel 13.
  • the channel 21 opens into the distribution chamber 22 between the two valves mentioned.
  • valve disk 5 is firmly pressed onto an annular collar 25 of a valve carrier 1 with a passage.
  • the valve disk 5 is supported with its passage against an axial stop 26 of the valve support 1.
  • the valve plate is loaded with a closing spring 12, which is designed as a conical helical spring and the other end of which is supported against an extension of the housing 17 in the region of the mouth of the channel 13.
  • the closing spring 12 loads the valve plate 5 in the closing direction and presses it against the valve seat 16.
  • the valve plate 6 is guided with a passage on a bolt-shaped extension 23 of the valve carrier 1 with a sliding guide. It is pressed by means of a compression spring 14 against a stop 15 located at the end of the bolt-shaped extension 23.
  • the compression spring surrounds the essentially cylindrical valve carrier 1 and is supported on the annular collar 25, on which the passage of the valve plate 5 is pressed.
  • valve carrier 1 has a shape which corresponds to the shape of the housing of a thermostatic working element of a thermostatic valve. This shape has been chosen in particular to show the corresponding correspondence with a thermostatic valve. Of course, however, a different design can be chosen for the valve carrier 1 since, in contrast to a housing of a thermostatic working element, it does not absorb any expansion material.
  • a rod 2 is rigidly attached to the valve carrier 1 in the axial extension thereof.
  • the rod 2 penetrates the housing part 8 having the connecting piece 9 in a guide 7 and protrudes outwards from this housing part 8.
  • the guide 7 consists of a bore in the housing part 8 and a screwed-in insert 20.
  • the insert 20 also holds a sealing element 19, in particular an O-ring surrounding the rod 2.
  • a ball 24 is inserted, which is opposite a drive cam 3.
  • the drive cam 3 is arranged on a drive shaft 11 of an electric motor 4, the drive shaft 11 running transverse to the axis of the rod 2 and the valve carrier 1.
  • the cam 3 has an eccentric shape with respect to the drive shaft 11.
  • the electric motor 4, which has, for example, a self-locking transmission, is on one. attached to the housing part 8 attached bracket 10.
  • the electric motor is provided with connections 18, to which a controller 28 is connected, via which the drive of the drive shaft 11 and thus the adjustment of the valve carrier 1 via the drive cam 3 and Rod 2 is controlled.
  • the controller input is connected to a number of signal transmitters, which are indicated by arrows and which, for example, the coolant temperature, the outside temperature, the load on the internal combustion engine, the torque or speed of the internal combustion engine, the exhaust gas values and the exhaust gas temperature, the negative pressure in the intake manifold, the oil temperature or the like . Detect and, depending on this, regulate the operating temperature of the engine by regulating the cooling in order to optimize the operation of the internal combustion engine. Since the valve carrier 1 with the valve disks 5 and 6 is driven directly by the electric motor 4, this results in fast regulation with relatively short control cycles.
  • a feedback potentiometer 27 is also connected to the controller 28, which is attached to the outside of the housing 8 and which is adjusted by the part of the rod 2 projecting outwards. This feedback potentiometer 27 reports the respective valve position, ie the position of the valve support 1, to the controller 28. Of course, other devices for reporting the valve position are also possible, for example a rotary potentiometer acting on the drive element 3.
  • actuators can also be provided instead of the electric motor, for example actuators that have a translatory movement and transmit this directly to the rod 2.
  • the drive means of the actuator can also be provided instead of the electric motor, for example actuators that have a translatory movement and transmit this directly to the rod 2.
  • the drive cam 3 can be provided with a dovetail-shaped groove following the eccentric cam profile, into which the rod 2 then engages with a hammer-head-like end.
  • the closing spring 12 can also be omitted.
  • the valve plate 5 is designed as a valve slide, to which a slide valve seat is then assigned. Care must then be taken that sufficient radial guidance is provided for the valve support 1 and the rod 2 if the closing spring 12 is omitted, which can be done, for example, by extending the guide.
  • valve plate 6 can also be designed as a valve slide, to which a slide valve seat of the channel 13 is then assigned.
  • the compression spring 14 can also be omitted.
