Bypass passageways 12.The bypass passageways 12 are concurrently formed on hydraulic with the throttling passage 10.Here, the bypass passageways 12 are at least
Generally extend on the longitudinal direction L of the hydraulic bearing 2.In order to ensure the desired length of the bypass passageways 12, the bypass
One section in channel 12 can protrude into the operating room 4.The bypass passageways pass through this point from the end side tip of the aforementioned section
Next door 8 extends in the region of the balance cylinder 6.At the end segments 32 towards the balance cylinder of the bypass passageways 12, by this
Circulation passage 12 has the cross section bigger than in the rest part of the bypass passageways 12.In other words, the cross of the bypass passageways 12
It is expanded in the associated end segments 32 in section.The flowing velocity of the hydraulic fluid reduces as a result, which can be with
Flow through the bypass passageways 12.
The end side tip 34 towards the balance cylinder 6 of the bypass passageways 12 is closed.Here, the end segments 32 are at least
A part can be made of valve 16 associated with the bypass passageways 12.That is, the valve 16 may be constructed the whole of the bypass passageways 12
Body portion.If opening the valve 16, hydraulic fluid can flow between the operating room 4 and the balance cylinder 6.It should if closed
Valve 16, then this is equally applicable to the bypass passageways 12.In other words, with locking or the bypass passageways 12 can be opened.For this purpose, the valve 16
With a cylindrical locking device 18.Here, the locking device 18 includes a cylindrical circular segments 52, the annular
One longitudinal axis end of section is closed by a cladding element 50.The locking device 18 is fastened on the rolling with the cladding element 50
At the radial inside edge 28 of dynamic diaphragm 26.Here, as shown in Figure 1, in the radial inside edge 28 and the (rolling of flange 44
Diaphragm 26 is tightly attached on the flange) between the region of rolling diaphragm 26 be used as reset spring 20, so as to by the locking device 18
It is offset in the position.This position of the locking device 18 is 18 lock position of locking device, should by the lock position
Valve 16 and thus the bypass passageways 12 can be locked up.Because the cylindrical circular segments 52 of the locking device 18 are closed herein
These cover sides of the valve 16 pass through window 22.These by window 22 be separated from each other on a ring or circular segments simultaneously
Row arranges.At these by forming contact pin 42 between window 22, these contact pin are by the valve 16 or the cover side wall of the bypass passageways 12
Portion is connect with the end side tip 34.
In order to open the valve 16 or the bypass passageways 12, (especially in the balance on the longitudinal direction L of the hydraulic bearing 2
On the direction of room 6) deviate the locking device 18.The locking device 18 release passes through the opening that window 22 is constituted by these as a result,
24, allow hydraulic fluid to flow through the bypass passageways 12 on the longitudinal direction L of the hydraulic bearing 2 first by the operating room 4,
Until hydraulic fluid hits the end side tip 34 (carrying out the deflection on transverse direction Q at the end side tip) so that the liquid
Press liquid then flows into the balance cylinder 6 by the opening 24 of window 22 by these on transverse direction Q.That is it realizes
The deflection of the flow direction.That is, the hydraulic fluid flows on transverse direction Q at valve 16 associated with the bypass passageways 12
Out.Transverse direction Q refers at least one direction of the longitudinal direction L transverse to the hydraulic bearing.In other words, which exists
It is flowed out in the radial direction by the bypass passageways 12.As previously mentioned, deviating the lock device on the longitudinal direction L of the hydraulic bearing 2
Part 18 is to open the valve 16.That is, deviating the locking device 18 by direction at the valve 16 transverse to the bypass passageways 12.For
Realization this point has a corresponding Linear guide by means of bearing with the associated valve 16 of bypass passageways 12.?
This, which refers preferably to the radially inner side surface of cylindrical circular segments 52 and passing through for the valve 16 in the locking device 18
Sliding bearing between the radial outside wall portion of the end segments 32 of the radial outside wall portion or bypass passageways 12 of window 22.
By deviating the locking device 18 by direction at the valve 16 transverse to the bypass passageways 12 to open or lock
Only bypass passageways 12, even if the valve 16 can also be opened or closed under the high-pressure situations in the operating room 4.Because acting on
Power (these power are caused by the hydraulic fluid in the bypass passageways 12 under pressure) on the locking device 18 transverse to
The direction orientation that the locking device 18 can deviate.Therefore, it only needs to overcome through the supporting member to deviate the locking device 18
Caused frictional force.For this purpose, small power is enough.Thus, it is proposed that the locking device 18 can be at least auxiliarily by being somebody's turn to do
Rolling diaphragm 26 is offset to the lock position.In order to open the valve 16 or the bypass passageways 12, can be set one it is unshowned
Actuator, the actuator and the locking device 18 are mechanically connected and can be on the longitudinal direction L of the hydraulic bearing 2 controllably
Deviate the locking device.
In order to further mitigate the resistance for the offset for resisting the locking device 18, the cladding element 50 of the locking device 18 exists
It can have multiple holes on longitudinal direction L, can be realized that (space is at this in the balance cylinder 6 and a space by this some holes
Constituted between cladding element 50 and the end side tip 34) between fluid communication.
