Bar I 10, extension bar I 10 connect the distribution valve rod I 9 on cylinder I 25.
Cylinder I 25 is identical with II 26 internal structure of cylinder, specific structure are as follows: the side on I 25 top of cylinder is equipped with air intake duct I
3, exhaust duct I 2, the other side are equipped with air intake duct II 8, exhaust duct II 7, and two air intake ducts are located on the outside of two exhaust ducts, two into
Air flue and two exhaust ducts respectively symmetrically, are equipped with exhaust outlet I 5 along cylinder axis among two exhaust ducts；II 26 top of cylinder
Side is equipped with air intake duct IV 22, exhaust duct IV 23, and the other side is equipped with exhaust duct III 16 and air intake duct III 17, and two air intake ducts are located at
Respectively symmetrically along cylinder axis, two exhaust ducts centres are equipped with row for two exhaust ducts outsides, two air intake ducts and two exhaust ducts
Port II 21；
Cylinder I 25 and II 26 two air intake ducts of cylinder and exhaust duct upper end are respectively equipped with the identical distributing valve I 4 of structure and match
Air valve II 20, the distributing valve I 4 and distributing valve II 20, valve seat section are symmetrical zigzag shape, distributing valve I 4 and distributing valve II
20 upper ends are all provided with fluted 27；Slider I 6 and sliding block II 19 are set on distribution valve rod I 9 and distribution valve rod II 18, it is sliding
The bottom of affixed two limited blocks 28 on the distribution valve rod at II 19 both ends of block I 6 and sliding block, slider I 6 and sliding block II 19 is placed in
In the groove 27 of distributing valve upper end, i.e., distribution valve rod I 9 and distribution valve rod II 18 are connected by slider I 6 and sliding block II 19 respectively
Connect distributing valve I 4 and distributing valve II 20；When distributing valve is in the center of cylinder side inlet and exhaust duct, distributing valve valve
The two sides of seat are covered each by the air intake duct of cylinder two sides and the outlet (see figure 4) of exhaust duct upper end.
The specific work process of the utility model: when piston and distributing valve are in the position Fig. 1, cylinder I left part in top is empty
Between steam through exhaust duct I 2, be discharged by exhaust outlet I 5, high steam enters the right space of cylinder I 25 from air intake duct II 8.This
When, piston I 1 drives piston rod I 12 under high steam promotion, and rocking bar II 14 moves downward.Meanwhile extension bar II 15 is also hauled,
Distribution valve rod II 18 and distributing valve II 20 move right.Distribution valve rod II 18 passes through sliding block II 19 and II 20 phase of distributing valve
Even.The mutual alignment of adjusting slider II 19 and distribution valve rod II 18 can control sliding block II 19 and II 20 back side groove of distributing valve
Gap.
When piston is in the position Fig. 1, distributing valve II 20 just starts to move right soon, following II left part space of cylinder
Air intake duct IV 22 is just opened, and high steam enters this space from air intake duct IV 22, forces piston II 24 to move right, and by vapour
The steam of II 26 right space of cylinder is arranged to exhaust duct III 16.
Since piston II 24 moves right, then piston rod II 13 is driven, rocking bar I 11 moves.The distributing valve of top cylinder I 25
Pull rod I 9 is identical as II 24 direction of motion of piston, and the slider I 6 of distributing valve I 4 is driven to move right together.
In sliding block 6 not in contact with before arriving 4 back side groove of steam distributing valve, steam distributing valve 4 is not moved.Sliding block 6 moves to contact and matches
After the groove of steam valve 4, steam distributing valve 4 starts to move right.
Mobile, this process moved together without hauling steam distributing valve, the referred to as null of steam distributing valve slider I 6 with vapour pull rod
Journey.Using this idle stroke, piston I 1 just closes exhaust duct I 2, stops steam discharge, forms steam cushion, so that piston is slowed down, until complete
Full cut-off gets off.At the same time, the distributing valve II 20 for the cylinder II 26 connecting with piston I 1 also reaches the position of bottom dead centre shown in Fig. 2
It sets.
When piston II 24 continues to move right, distributing valve I 4 also does equidirectional movement.Until distributing valve I 4 just covers
Until when living in I 25 left part space air intake duct I 3 of side cylinder and right part cylinder exhaust duct II 7, piston I 1 remains motionless.This
The mutual alignment of moment, each component are indicated in Fig. 2.
When piston II 24 continues to move right, air intake duct I 3, the exhaust duct II 7 of cylinder I 25 are opened, piston I 1 start to
It moves right, by rocking bar II 14, extension bar II 15 drives the sliding block II 19 of distributing valve II 20 to move, until idle stroke of passing by, sees figure
3.Piston II 24 closes exhaust duct III 16 using the idle stroke of steam distributing valve sliding block II 19, forms steam cushion, finally stops.Meanwhile
The steam distributing valve of cylinder I 25 has fully opened air intake duct I 3, exhaust duct II 7.
The pause of piston II 24 will continue to that always the distributing valve II 20 being moved to the left opens air intake duct III 17, exhaust duct IV
Until 23.It begins to move up later, sees Fig. 3.In later movement, the mutual alignment of each valve actuating mechanism repeats above-mentioned dynamic again
Make.
