As shown in (b) of Fig. 4, clutch CL is completely cut through when being loaded using the pressing formed by electric hydraulic pump 21
When, that is, when the 2nd release plunger 32 and the 1st release plunger 31 are in the state of against each other and in the figure of clutch release cylinder 33
When axial right part abuts, stop electric hydraulic pump 21.In this case, since the 2nd switching valve 23-1 is in close state, because
This, hydraulic (the 2nd hydraulic PO2) of the 2nd space R2 is maintained at constant.As a result, being pressed using what is formed by the 2nd hydraulic PO2
Pressure load is to maintain clutch dissengaged positions.
When user's let slip the clutch 11, by the oil compression in clutch master cylinder 14, thus by compressed oil via the 1st
Hydraulic supply line 16 is supplied to the 1st space R1.So that hydraulic (the 1st hydraulic PO1) of the 1st space R1 increases.The situation
Under, the pressing load that is formed by the 1st hydraulic PO1 and the pressing load that is formed by the 2nd hydraulic PO2 by the 2nd release plunger 32 and
Interaction.
(the 1st hydraulic PO1) shape is operated by the clutch pedal of user when the pressing load formed by the 2nd hydraulic PO2 is greater than
At pressing load when, the load difference absorbed via the 1st switching valve 17-1 and hydraulic suction line 17 by accumulator 18.
Also, as shown in (c) of Fig. 4, when the clutch pedal of user, which operates, to be completed, that is, when main piston 13 and clutch
The figure axis of device master cylinder 14 to the right end abutment when, make the 1st switching valve 17-1 become closed state and the 2nd switching valve 23-1 becomes
Opening state.
By being in close state the 1st switching valve 17-1 so that oil from accumulator 18 be released and via bypass
Pipeline 19 is supplied to the 1st space R1 for hydraulic.Make the 2nd release plunger 32 towards figure using being loaded by the pressing of the hydraulic formation
Axis moves to the left.In this case, since the 2nd switching valve 23-1 is in the open state, oil is passed through from the 2nd space R2
Fuel outlet valve 25 is expelled to by the 2nd switching valve 23-1 and recovery pipe 23.In addition, using released from accumulator 18 hydraulic and by
1 release plunger 31 maintains the state with the figure axis of clutch release cylinder 33 end abutment to the right.As a result, using by from
The press load for the hydraulic formation that accumulator 18 is released maintains clutch dissengaged positions.
As shown in (d) of Fig. 4, user starts to return to clutch pedal 11.In this case, main piston 13 is stepped on by clutch
Plate 11 pulls.Thus make hydraulic as negative pressure in clutch master cylinder 14.As a result, make oil in the 1st space R1 and from
The oil that accumulator 18 is released is inhaled into clutch master cylinder 14 via the 1st hydraulic supply line 16.As a result, making the 1st sky
Between hydraulic (the 1st hydraulic PO1) of R1 reduce, the pressing load formed by the 1st hydraulic PO1 is lower than coming from clutch case CLC (Fig. 1)
Elastic force.Thus the 1st release plunger 31 is pushed back to the left towards figure axis.Thus clutch CL is engaged.Then, work as clutch
When pedal 11 restores completely, so that the 2nd switching valve 23-1 becomes closed state.Finally, become with it is initial shown in (a) of Fig. 2
State is the same.
In this way, when electric hydraulic pump 21 cut off clutch CL after make user clutch pedal operate intervention when, by with
