Next, with reference to Fig. 1,7 and 9-16 the work of valve lift regulating device 20 is described.

Be positioned under the low locational Fig. 1 state of engine speed at slider 50, when camshaft 11 rotation, rotatablely moving of low engine speed cam 25 is transmitted to intake valve 44 and therefore is converted into the linear reciprocating motion of intake valve 44 by roller Rocker arm 40.

Under the state of Fig. 1, the latch lever 90 of actuator 70 is positioned on the neutral position, as shown in Figure 7.Under latch lever 90 was positioned at state on the neutral position, the first output pin 105 and the second output pin 110 engaged latch levers 90.Therefore, the axial motion of the axial motion of the first output pin 105 and the second output pin 110 is restricted in the relevant position, and on this phase position, the first output pin 105 and the second output pin 110 separate with slider 50.

During high engine speed scope under arriving Fig. 1 state, when the first output pin 105 was consistent with the position of the first protuberance 54 with respect to the circumferential position of slider 50 along slider 50 circumferencial directions, the driver element 100 of actuator 70 gives coil 102 energisings so that fixed core 101 magnetization.Therefore, the first removable pin 80 is attracted to this axial sidepiece, is fixed core 101 sides by magnetic force, and therefore latch lever 90 is rotated on the first rotational position, as shown in Figure 9.On the first rotational position, latch lever 90 engages with the second output pin 110 and throws off with the first output pin 105.When the first output pin 105 was thrown off with latch lever 90, the thrust of the first delivery spring 109 made the first output pin 105 move axially towards slider 50 sides.Therefore, the first output pin 105 is installed in the engaging groove 51.

Under the first output pin 105 was accommodated in Figure 11 state in the engaging groove 51, when slider 50 was rotated with camshaft 11, the first inclined surface 55 of the first protuberance 54 of slider 50 engaged the first output pin 105.Therefore, the axial position of slider 50 is restricted, and slider 50 slides on the high engine speed position, shown in the arrow A 1 of Figure 11 like that.When slider 50 slided on the high engine speed position, the first rise surface 64 of engaging groove 51 was along promoting radially outwardly the first output pin 105, and therefore the first output pin 105 removed from engaging groove 51.When the first rise surface 64 of slider 50 when promoting the first output pin 105 radially outwardly, the first slidingsurface 108 of the first output pin 105 is directed in the first circular groove 106 in latch lever 90 enterprising line slips and latch lever 90.

Be positioned under the locational Figure 12 state of high engine speed at slider 50, when camshaft 11 rotation, rotatablely moving of high engine speed cam 30 is passed in the intake valve 44 by roller Rocker arm 40, and therefore is converted into the linear reciprocating motion of intake valve 44.Be converted into rotatablely moving of high engine speed cam 30 in the situation of linear reciprocating motion of intake valve 44, the lift of intake valve 44 has increased than the situation of the linear reciprocating motion that rotatablely moving of low engine speed cam 25 is converted into intake valve 44.

When arriving the low engine speed range of Figure 12 state, when the first output pin 105 is consistent with the position of the second protuberance 58 with respect to the circumferential position of slider 50 along the circumferencial direction of slider 50, thereby actuator 70 drives the first output pin 105 the first output pin 105 is arrived in the engaging groove 51.

Slide in state moving device 50 when being rotated with camshaft 11 when be accommodated in Figure 13 in the engaging groove 51 at the first output pin 105, and the second inclined surface 59 of the second protuberance 58 of slider 50 engages with the first output pin 105.Therefore, the axial position of slider 50 is restricted, and reaches slider 50 and slides on the low engine speed position, and is such shown in the arrow A 2 of Figure 13.When slider 50 slided on the low engine speed position, the first output pin 105 was by the second rise surface 66 of engaging groove 51 and along being pushed radially outwardly, and therefore removed from engaging groove 51.

During low engine loading scope under arriving Fig. 1 state, when the second output pin 110 was consistent with the position of the second protuberance 58 with respect to the circumferential position of slider 50 along slider 50 circumferencial directions, the driver element 100 of actuator 70 gives coil 104 energisings so that fixed core 103 magnetization.Therefore, the second removable pin 83 is attracted to this axial sidepiece, is fixed core 103 sides by magnetic force, and therefore latch lever 90 is rotated on the second rotational position, as shown in Figure 10.On the second rotational position, latch lever 90 engages with the first output pin 105 and throws off with the second output pin 110.When the second output pin 110 was thrown off with latch lever 90, the thrust of the second delivery spring 114 made the second output pin 110 move axially towards slider 50 sides.Therefore, the second output pin 110 is installed in the engaging groove 51.

Be accommodated under the state of the Figure 14 in the engaging groove 51 at the second output pin 110, when slider 50 was rotated with camshaft 11, the second inclined surface 59 of the second protuberance 58 of slider 50 engaged the second output pin 110.Therefore, the axial position of slider 50 is restricted, and slider 50 slides on the low engine loading position, shown in the arrow A 3 of Figure 14 like that.When slider 50 slided on the low engine loading position, the second rise surface 66 of engaging groove 51 was along promoting radially outwardly the second output pin 110, and therefore the second output pin 110 removed from engaging groove 51.When the second rise surface 66 of slider 50 when promoting the second output pin 110 radially outwardly, the second slidingsurface 113 of the second output pin 110 is directed in the second circular groove 111 in latch lever 90 enterprising line slips and latch lever 90.

Be positioned at slider 50 under the state of low locational Figure 15 of engine loading, when camshaft 11 rotation, roller Rocker arm 40 is not swung.Therefore, do not produce the opening and closing campaign of intake valve 44.In this mode, respective cylinder has stopped, and therefore fuel consumption improves.In addition, in the situation that hybrid vehicle, regeneration of energy efficient has improved.

Under the state of Figure 15, when outside low engine loading scope, driving motor, when the second output pin 110 is consistent with the position of the first protuberance 54 with respect to the circumferential position of slider 50 along the circumferencial direction of slider 50, thereby driving the second output pin 110, actuator 70 make the second output pin 110 enter into engaging groove 51.

Under the second output pin 110 was contained in Figure 16 state in the engaging groove 51, when slider 50 was rotated with camshaft 11, the first inclined surface 55 of the first protuberance 54 of slider 50 engaged the second output pin 110.Therefore, the axial position of slider 50 is restricted, and reaches slider 50 and slides on the low engine speed position, and is such shown in the arrow A 4 of Figure 16.When slider 50 slides on the low engine speed position, along promoting radially outwardly the second output pin 110, and therefore, the second output pin 110 is removed from engaging groove 51 by the first rise surface 64 of engaging groove 51.

As discussed above such, in the first embodiment's actuator 70, joint between the first output pin 105 and latch lever 90 is released, thereby when the first removable pin 80 is shifted to this axial sidepiece, make the first output pin 105 shift to slider 50, and make the second removable pin 83 shift to this another axial sidepiece.In addition, in actuator 70, joint between the second output pin 110 and latch lever 90 is released, thereby makes the second output pin 110 shift to slider 50 when the first removable pin 80 is shifted to this another axial sidepiece, and makes the second removable pin 83 shift to this axial sidepiece.

Here, it should be noted, when the first removable pin 80 and the second removable pin 83 owing to having applied external vibration and/or exterior vibration and during along its axial vibration, the first removable pin 80 and the second removable pin 83 can move towards common axial sidepiece.Therefore, if be not to shift to separately disalignment to sidepiece at the first removable pin 80 and the second removable pin 83, in the latch lever 90 non-rotary situations, the same with the present embodiment so, it is possible avoiding carrying out wrong rotation by the latch lever 90 that application external vibration and/or exterior vibration cause.

In addition, in the first embodiment, the first output pin 105 and the second output pin 110 are so arranged, so that the first output pin 105 axially and the second output pin 110 axially be substantially perpendicular to imaginary plane, this imaginary plane comprises the sense of rotation (this sense of rotation and this another sense of rotation) of latch lever 90.Therefore, owing to using external vibration and/or exterior vibration and when moving axially, be applied to rotation that power latch lever 90 on can not cause latch lever 90 from the first output pin 105 and the second output pin 110 when the first output pin 105 and the second output pin 110.Therefore, avoiding latch lever 90 is possible by the mistake rotation that application external vibration and/or exterior vibration cause.

Consequently, under the state that driver element 100 is stopped restriction the first output pin 105 and/or the second output pin 110 to move towards slider 50 sides be possible.Therefore, prevent that caused damage is possible on the first output pin 105 and the second output pin 110 by excessive load is applied in actuator 70, wherein this excessive load is owing to following reason causes, and namely the first output pin 105 and the second output pin 110 touch and be different from diverse location engaging groove 51, slider 50.

In addition, in the first embodiment, thereby the first spring 98 promotes the first removable pin 80 latch lever 90 is rotated along this another sense of rotation (clockwise direction of Figure 10).In addition, the second spring 99 promotes the second removable pin 83, thereby latch lever 90 is rotated along this sense of rotation (counter clockwise direction of Fig. 9).Therefore, when driver element 100 makes latch lever 90 along this sense of rotation (counter clockwise direction of Fig. 9) when being rotated, the Driving force of the second spring 99 is applied in to make latch lever 90 to be rotated along this sense of rotation.Consequently, can reduce the working load of driver element 100.In addition, when driver element 100 makes latch lever 90 along this another sense of rotation (clockwise direction of Figure 10) when being rotated, the Driving force of the first spring 98 is applied in to make latch lever 90 to be rotated along this another sense of rotation.Consequently, can reduce the working load of driver element 100.Therefore, the size of driver element 100 can reduce, and therefore the size of actuator 70 can reduce.

In addition, in the first embodiment, under latch lever 90 was positioned at state on the neutral position, the flange 82 of the first removable pin 80 was pushed against on a part of inwall of engaging groove 94 (top of Fig. 7), and this part inwall is positioned on this another axial sidepiece (upside of Fig. 7).Therefore, between the flange 82 of the first removable pin 80 and a part of inwall of engaging groove 94 (bottom of Fig. 7), form the gap, wherein should be positioned on this axial sidepiece (downside of Fig. 7) by part inwall.In addition, when latch lever 90 was on the neutral position, the flange 85 of the second removable pin 83 was pushed against on a part of inwall of engaging groove 95 (top of Fig. 7), and this part inwall is positioned on this another axial sidepiece (upside of Fig. 7).Therefore, form the gap between a part of inwall (bottom of Fig. 7) of flange 85 and engaging groove 95, this part inwall is positioned on this axial sidepiece (downside of Fig. 7).

Therefore, when the first removable pin 80 or the second removable pin 83 are shifted to this axial side (downside of Fig. 9 or Figure 10), owing to existing above-mentioned respective clearance to limit that latch lever 90 is caught (prevention) first removable pin 80 and the second removable pin 83 is possible.In addition, when the first removable pin 80 is shifted to this axial sidepiece (downside of Fig. 9) owing to there being above-mentioned respective clearance so that the travelling speed of the first removable pin 80 can be accelerated be contiguous to time of latch lever 90 at the first removable pin 80 before.Consequently, latch lever 90 can rotate rapidly.In addition, when the second removable pin 83 is shifted to this axial sidepiece (downside of Figure 10) owing to there being above-mentioned respective clearance so that the travelling speed of the second removable pin 83 before the second removable pin 83 is contiguous to time on the latch lever 90, can be accelerated.Consequently, latch lever 90 can fast rotational.

In addition, in the first embodiment, when when the first output pin 105 is thrown off with latch lever 90, the first output pin 105 is when axially shifting to slider 50 side, and the first taper protuberance 107 of the first output pin 105 has formed surface-p-Surface Contact with the first conical surface 77 of housing 71.In addition, when when the second output pin 110 is thrown off with latch lever 90, the second output pin 110 is when axially shifting to slider 50 side, and the second taper protuberance 112 of the second output pin 110 has formed surface-p-Surface Contact with the second conical surface 78 of housing 71.

Consequently, the first output pin 105 and the second output pin 110 each springback capacity from slider 50 can be reduced or minimize after abutting slider 50.Therefore, the first output pin 105 and the second output pin 110 each can be inserted into reliably in the engaging groove 51 of slider 50.

In addition, in the first embodiment, the fixed core 101 of driver element 100 and fixed core 103 form one with the support 72 of housing 71.Therefore, the quantity of part can reduce or minimize.

When the first output pin 105 and the second output pin 110 move with respect to housing 71, enter into the oil of housing 71 inside from slider 50 sides as oiling agent (lubricant oil) by the first supported hole 790 and the second supported hole 795.But under the temperature environment of cold (for example cold winter) condition, because the oil viscosities in the housing 71 increase, therefore the first and second output pins 105, the 110 and first and second

removable pins

80,83 each travelling speeds can adversely reduce.In the first embodiment, in order to solve this shortcoming, therefore switch on simultaneously (can switch on simultaneously) for coil 102 and coil 104 at driver element 100, thereby coil 102 and coil 104 have produced heat and have therefore heated the interior oil of housing 71.Therefore, can prevent that the oily viscosity in the housing 71 from increasing, and therefore can prevent the first and second output pins 105, the 110 and first and second

removable pins

80,83 each travelling speeds reduce.
