Steam-cylinder piston 29 has end face 53,54 each other backwards.First end face 53 limits first chamber 31, second end face
54 limitation second chambers 32.End face 53,54 has been carried out various sizes of effective cross section 53,54.Horizontal stroke based on action bars 30
Section (it is determined by the diameter 55 of action bars 30), the having relative to first end face 53 of effective cross section 54 of second end face 54
Effect cross section 53 reduces.(it is equal to initial pressure to the pressure of pressure fluid in chamber 31,32 under idle state
Power), the tensile force 56 synthesized, the tensile force of the synthesis is applied on piston 29.The tensile force 56 of synthesis is in this implementation
Pointed to straight down in example, because it works along vertically-oriented axis of movement 46.The tensile force 56 of synthesis is added to counterweight 20
On, wherein, the power and tension balance rope 5.
Therefore, Hydraulic Elements 26 are designed to, the pressure fluid default, under initial pressure in chamber 31,32
38 load steam-cylinder piston 29 with the tensile force 56 of synthesis, and the tensile force of the synthesis passes through steam-cylinder piston 29 and at least one deflecting roller
14th, 15 (together with counterweight 20) tension balance rope 5.Therefore, (wherein, lived in an initial condition or under poised state in cylinder
The passage of obvious steam-cylinder piston is not produced in the casing bore 28 of plug 29), balance rope 5 is tensioned by power, and the power is more than counterweight

Choke valve 60 and reversal valve 62 be directed into chamber 32.When pressure fluid 38 is extruded from chamber 32, pressure fluid
38 are directed into chamber 31 by choke valve 63 and reversal valve 64.Here, coordination can be realized by adjustable choke valve 60.
On the contrary, when by balance rope 5, by deflecting roller 14,15, by pulling force, (its size, which is that the pulling force may result in, does not wish
The regulation of deflecting roller 14,15 motion hoping, making balance rope 5 relax) when being applied on steam-cylinder piston 29, valve gear 34 prevents chamber
The exchange of pressure fluid 38 between room 31,32.Here, it is further assumed that, also it is not reaching to maximum system pressure.It is such
The bounce that larger pulling force can be for example by counterweight 4 or the rope by balance rope 5 are segmented 16,17 obvious horizontal rolling
It is dynamic to cause.Here, when upstream direction is operated steam-cylinder piston 29 in quick motion, then produced in chamber 31 larger
Boost in pressure.Thus, the distributing valve 61 for being designed to the distributing valve 61 of pressure operation is switched to blocked state 65.Thus, pressure
The outflow of fluid from first chamber 31 is prevented from.On the contrary, if steam-cylinder piston 29 is downwardly applied to, (this corresponds to pressure fluid 38
It is extruded from second chamber), then pressure fluid is pressed through choke valve 63 and commutation from second chamber 32 to first chamber 31
Valve 64 is still possible.The regulation motion of the tension balance rope 5 of deflecting roller 14,15 also keeps being possible.Therefore,
The unilateral prevention of steam-cylinder piston 29 has been obtained in this case, wherein, steam-cylinder piston 29 and and then also deflecting roller 14,15
It can only be adjusted downwardly.Therefore, following function has been obtained：The bounce of counterweight 4, the rope of balance rope 5 are segmented 16,17
Excessive horizontal jitter and similar motion are prevented from.
