Such as Fig. 2, third flow path 19 is additionally provided in main casing 2, third flow path 19 is for being connected to when piston 8 is advanced (to the right
Advance) 8 forward and backward side inner cavity 7 of piston.
19 right end of third flow path has a locating aperture 20, and the left-right position of locating aperture 20 is preset.
Second flow path 15 and third flow path 19 have the part being overlapped, to make door closer more miniaturization.Flow path coincidence part
Lease making crosses pinion gear 10 to lubricant transfer pinion 10.
There are three communication port 21, three communication ports 21 exist for the left end setting of 19 intersection of second flow path 15 and third flow path
Distribution (being distributed in the front and rear direction that piston 8 is advanced) on left and right directions, for changing open and close door speed.
Such as Fig. 3, door is manually opened.Door by coupling mechanism 3(referring to Fig. 1) in the first arm 4 act on gear shaft 11, tooth
Wheel shaft 11 drives pinion gear 10 to rotate clockwise, and pinion gear 10 drives the rack gear 18 engaged with pinion gear 10 to move right, thus
Piston 8 is set to move right.At this moment check valve 12 is in the open state, and hydraulic oil passes through first flow path 13 from 8 direction of travel of piston
The first chamber 26 of front side flows into the second chamber 27 on rear side of 8 direction of travel of piston.When piston 8 is advanced, main spring 9 is persistently pressed
It contracts and accumulates shutdown energy.
Such as Fig. 3, if piston 8 not yet blocks the locating aperture 20 of third flow path 19 after advancing to the right.Such as Fig. 4, if at this moment
Enabling power is removed, the shutdown energy release that main spring 9 is accumulated applies active force to the left to piston 8.Check valve 12 will be first-class
Road 13 blocks, and 26 hydraulic oil of first chamber flows to second chamber 27 by third flow path 19.Piston 8 is fallen back to the left until initial bit
It sets and (corresponds to door completely closed state), since the current limliting of third flow path 19 makes a slowly closing.
Such as Fig. 5, if piston 8 blocks the locating aperture 20 of third flow path 19 after advancing to the right when opening the door, third flow path 19
It is blocked.If at this moment remove enabling power, main spring 9 accumulate shutdown energy have releasing trend to piston 8 apply to
Left active force, check valve 12 block first flow path 13, and first chamber 26 is not connected to second chamber 27, shape in first chamber 26
At negative pressure, positive pressure is formed in second chamber 27, the differential pressure action of first chamber 26 and second chamber 27 is formed to the right in piston 8
Active force is opposite with to the left active force of the main spring 9 to piston 8 anti-, to keep piston 8 static, so that a holding be made to stop determining shape
State.And main spring 9 is greater than to the active force to the left of piston 8, to fight slightly to the active force to the right that piston 8 is formed by pressure difference
The interference of external force such as wind-force on the door.
Such as Fig. 6, the pressure difference of first chamber 26 and second chamber 27 is pushed away to the right by 15 pairs of formation of shutdown valve 16 of second flow path
Power, thrust and the abutting power of 17 pairs of shutdown valves 16 of little spring to the left are in conflicting mode.If applying door closing force on the door, first chamber
26 and the pressure difference of second chamber 27 further increase, differential pressure action is further increased in the thrust to the right that shutdown valve 16 is formed, directly
The abutting power of 17 pairs of shutdown valves 16 of little spring is overcome to thrust and shutdown valve 16 is removed that (shutdown valve 16 moves right from position is pushed against
It is dynamic), second flow path 15 is switched on and forms access, and first chamber 26 is connected to by second flow path 15 with second chamber 27, and passes through pressure
Difference effect makes in second chamber 27 hydraulic oil flow to first chamber 26 by second flow path 15.Piston 8 is fallen back to the left, and door is closed.
When piston 8 is fallen back to the left to releasing to locating aperture 20 when blocking, such as Fig. 4 state, at this moment shutdown valve 16 is multiple again
Second flow path 15 is blocked, if removal shutdown power, hydraulic oil flow to first chamber from second chamber 27 by third flow path 19
26, piston 8 is slowly mobile to the left under 9 push effect of main spring, door slowly closing.
In this example, adjusting block 28 is installed on main casing 2, little spring 17 is pushed against between adjusting block 28 and shutdown valve 16.It adjusts
The left-right position of locking nub 28 is adjustable setting, for example adjusting block 28 is threaded in main casing 2, so that little spring 17 be made to push against
The dynamics of shutdown valve 16 is adjustable namely the abutting power of 17 pairs of shutdown valves 16 of little spring is adjustable setting.Door adjustable in this way
Required door closing force after stopping surely.And door closer can also be further converted to and close door with what automatic time delay closed a function
Device: as shown in figure 14, further turning the abutting power that little spring 17 pushes against shutdown valve 16 down (adjusting block 28 further moves to right), when
When piston 8 moves to right end after enabling (Men Kaizhi amplitude peak), enabling power is removed, and do not apply shutdown power, make to press
The main spring 9 of contracting generates active force to the left to piston 8, and pressure difference forms to the right shutdown valve 16 in fluid locating for shutdown valve 16
Motive force overcomes the abutting power of little spring 17, and the very little distance so that shutdown valve 16 only slightly moves right, hydraulic oil is with small
Flow flowed on the left of shutdown valve 16 right side, door slowly closing.The abutting power for adjusting little spring 17 makes by shutdown valve 16
Flow it is sufficiently small so that piston 8 fallen back to the left from least significant to release to locating aperture 20 block experience it is enough when
Between, so that door is it slowly enough closed, achieve the effect that automatic time delay closes door.
The left-right position of locating aperture 20 is by setting, when piston 8 marches to the right the moment for blocking locating aperture 20,
The corresponding angle that door is opened is 75 ° ~ 85 °, and at this moment removing enabling power rear door can stop to determine, and piston 8 continues to right lateral
