Definitions

  • the present invention refers to a mechanical coolant pump for an internal combustion engine.
  • a mechanical coolant pump is driven by the combustion engine, for example by using a driving belt driving a driving wheel of the pump, so that the rotational speed of the coolant pump is proportional to the rotational speed of the combustion engine.
  • mechanical coolant pumps are provided with an outlet valve arrangement for controlling the coolant flow leaving the coolant pump. As long as the combustion engine is cold, the outlet valve is closed so that the circulation of the lubricant is reduced, minimized or completely stopped, with the result that the combustion engine warming-up phase is shortened.
  • FR2719100 A1 discloses the general principle of a rotary eccentric plug valve used in water circuit.
  • WO 2010/146609 A1 discloses a mechanical coolant pump according to the preamble of claim 1.
  • WO2011/95907 A1 and JP 48104103 disclose mechanical coolant pumps with outlet valve arrangements including a valve flap with a valve pivot axis lying within the plane of the flap.
  • WO 2011/101019 A1 discloses an impeller-type coolant pump with an outlet valve arrangement in the root of an outlet channel. The output valve arrangement is provided with a valve flap whereby the pivot axis of the valve flap is arranged at one end of the flap body and is provided in the surface plane of the valve seat.
  • the valve flap should to be pivotable even at high rotational speed of the pump rotor at which a high fluid pressure against the valve flap either in closing direction or in opening direction can occur. However, to guarantee full functionality at all rotational speeds, high actuation power is needed.
  • the mechanical coolant pump according to claim 1 is provided with an impeller pump wheel pumping the liquid coolant incoming in axial direction radially outwardly into an outlet volute.
  • the outlet volute is continuing into an outlet channel of the pump.
  • an outlet valve arrangement is provided whereby the outlet valve arrangement comprises a valve flap being movable between an open position and a closed position to leave open or to close the valve opening of the outlet channel.
  • the valve opening of the outlet channel is defined by and surrounded by a valve seat.
  • the valve seat is a closed contact line of the valve opening and the corresponding flap seat of the valve flap in the closed valve position.
  • the valve seat defines a general valve seat plane. If the valve seat is not completely lying in one single plane because some portions of the valve seat are somehow curved, then the valve seat plane is defined by a general geometric middle plane comprising two linear lateral seat portions parallel to each other.
  • a symmetry plane is provided in the middle of the valve opening and of the valve seat plane. The symmetry plane is exactly rectangular to the valve seat plane and parallel to a pivot axis of the valve flap.
  • the valve flap is pivotable or rotatable around the pivot axis which is parallel to the symmetry plane but the pivot axis is not located in the symmetry plane.
  • the pivot axis is located with a lateral eccentricity from the symmetry plane, whereby the lateral eccentricity is between 1/20 and 1/1 of the pivot axis' distance to the valve seat plane.
  • the valve flap can be realized as a plane body but is preferably realized as a cylindrical body.
  • At least one axial end of the valve flap is fixed to a base disc which is arranged rectangular to the pivot axis.
  • two base disks are provided at both axial ends of the valve flap.
  • the base disc is provided in a corresponding recess of the pump housing, respectively, so that the proximal surface of the base disk is lying in the plane of the inner wall surface of the outlet channel.
  • the base disk extends the surface of the volute housing continuously, especially in the open position of the valve flap.
  • the base disk can be, in part, circular with respect to the pivot axis so that the inner surface of the outlet channel is stepless.
  • the volute housing is provided with a recess for housing the valve flap in its open position.
  • the valve flap In the open valve position, the valve flap is substantially housed in the recess so that the valve flap does not project substantially into the outlet volute or into the outlet channel. Therefore, the flow resistance caused by the valve flap is reduced to a minimum.
  • the pivot axis is lying within the projection of the valve seat so that the eccentricity is less than half of the width of the valve seat projection.
  • the lateral eccentricity does not exceed 1 ⁇ 2 of the valve flap width which is the flaps extend in a direction rectangular to the pivot axis.
  • valve flap is provided with a valve flap body and the flap seat is coated with a rubber coating.
  • the rubber coating of the flap seat improves the tight sealing of the closed valve flap.
  • the outlet volute housing defines a second outlet channel which is not effected by the outlet valve arrangement and remains always open so that a minimum coolant flow is always guaranteed as long as the pump wheel is driven by the internal combustion engine.
  • internal combustion engines with high performance as for example truck engines, need always to be cooled with a minimum coolant flow rate to avoid heat pockets.
  • a second outlet channel without any a valve is absolutely fail safe with respect to a minimum coolant flow.
  • the flap body is actuated by a pneumatic, electric or thermostatic actuator.
  • the needed actuation force for guaranteeing a reliable function of the valve is relatively low.
  • the proximal surface of the valve flap body extends the volute housing wall surface or the channel wall surface continuously in the open position of the flap body. This means that in the open state of the flap body, the proximal flap body surface continues the surface of the volute or the outlet channel smoothly and steplessly so that the flow resistance as low as possible.
  • the figures 1 to 6 show a mechanical coolant pump 10 for circulating a coolant for an internal combustion engine.
  • the coolant pump 10 can be directly mounted to an engine block of the internal combustion engine.
  • the coolant pump 10 is provided with a driving wheel (not shown) which can be driven by a driving belt which is directly driven by the internal combustion engine.
  • the rotational speed of the coolant pump 10 is proportional to the rotational speed of the internal combustion engine.
  • the coolant pump 10 is provided with a pump housing 12 housing an impeller pump wheel 14 pumping a liquid coolant incoming in axial direction radially into an outlet volute 16.
  • the outlet volute 16 is defined by a volute housing 13 which is a part of the pump housing 12.
  • the axial coolant pump inlet is provided at the bottom side of the coolant pump 10 shown in figures 1 and 2 .
  • the outlet volute 16 includes a first outlet channel 18 and a second outlet channel 17 which is separated by a separating wall 20 from the first outlet channel 18.
  • the coolant pump 10 is provided with an outlet valve arrangement at a valve opening 19 at the beginning of the first outlet channel 18.
  • the outlet valve arrangement is provided with a valve flap 30 which is pivotable between a closed position and an open position as shown in figures 2 and 1 or in figures 3 and 4 .
  • the valve flap 30 closes or opens the valve opening 19 of the first outlet channel 18 but does not effect the coolant flow into and through the second outlet channel 17.
  • the integral metal valve flap 30 is provided with a circular flap body 32 with an axial orientation of its general valve seat plane.
  • the flap body 32 has a proximal surface 33 and a distal surface 35.
  • the flap body 32 is, somehow, a circumferential section of a hollow cylinder wall.
  • the flap body 32 is axially arranged between a first circular base disk 34 and an identical second base disk 38 at both axial ends of the flap body 32.
  • the valve flap 30 is supported in pivot bearings at both axial ends, so that the valve flap 30 is pivotable around an axial valve pivot axis 31 which is arranged within the outlet volute 16.
  • the flap body 32 In the open position of the valve flap 30, as shown in figures 1 and 4 , the flap body 32 is housed in a housing recess 24 of the volute housing 13 so that the proximal surface 33 of the flap body 32 continues or extends the inside wall surface of the volute housing 13 continuously and without any relevant surface steps. As a result, the flow resistance caused by the flap body 32 in the open position is low even at high coolant flow rates.
  • the proximal side 33 of the flap body 32 is orientated to the outlet volute 16 whereas the distal side 35 of the flap body 32 is orientated to the housing recess 24 recessing the flap body 32.
  • a rubber coating 40 is provided over the entire flap seat. The rubber coating 40 improves significantly the sealing quality of the flap body 32 in the closed valve position, as shown in figures 3 and 5 .
  • the first and the second base disk 34, 38 are both completely recessed in corresponding housing recesses 42, 44 of the volute housing 13. As a consequence, both base disks 34, 38 do not cause any relevant flow resistance even at high coolant flow rates, in the open valve position.
  • the valve is provided with a valve shaft 52 fixed to one base disk 38.
  • the valve shaft 52 defines the pivot axis 31.
  • the valve shaft 52 is provided with a lever arm 54 which is actuated by a pneumatic actuator 50, as can be seen in figures 5 and 6 .
  • valve seat 66 which corresponds with a flap seat of the valve flap 30.
  • the valve seat 66 and the flap seat are completely in contact with each other in the closed valve position as shown in figure 3 .
  • the valve seat 66 defines a valve seat plane 60 which represents the general plane 60 of the complete valve seat 66.
  • the valve seat 66 is defined by two linear lateral seat portions which are parallel to each other and by two circular seat portions connecting the lateral portions.
  • the diameter of the circular seat portions is almost equal to the diameter of the flap body 32.
  • the lateral seat portions are parallel to the pivot axis 31.
  • the valve seat 66 has a width W which is the lateral distance between the two linear lateral seat portions.
  • a symmetry plane 62 is defined in the middle of the valve seat plane 60.
  • the symmetry plane 62 is rectangular to the valve seat plane 60.
  • the pivot axis 31 of the valve flap 30 is parallel to the symmetry plane 62 and to the valve seat plane 60.
  • the pivot axis 31 is provided with a distance D to the valve seat plane.
  • the distance D of the pivot axis 31 to the valve seat plane 60 is between 1 ⁇ 2 and 3/1 of the valve seat width W.
  • the pivot axis 31 is not lying in the symmetry plane 62 but is provided with an eccentricity E distant from the symmetry plane 62.
  • the eccentricity E is between 1/20 and 1/1 of the pivot axis' distance D of the valve seat plane 60. In the present case, the eccentricity E is about 1/3 of the pivot axis' distance D.
