As shown in Figure 3, this valve shaft 16 is provided with one first fluting, 26 and 1 second fluting 28.This valve shaft 16 also is provided with one first ring seat 30, one second ring seat 32 and one the 3rd ring seat 34.Be provided with three Teflon rings 36,38 and 40 on first ring seat 30, second ring seat 32 and the 3rd ring seat 34, it is used to prevent take place fluid and reveals between valve shaft 16 and hollow cylinder 14.
As shown in Figure 2, a rotor 42 is fixed on this valve casing 12, and it operationally links to each other with the key 44 that extends out from valve shaft 16 as shown in Figure 3.This rotor 42 can be little electric motor or any similar rotating machinery commonly known in the art.
As shown in Figure 3, first of valve shaft 16 fluting 26 and second fluting 28 is arranged on the opposite side of valve shaft 16.Therefore, as shown in Figure 1, when this valve shaft 16 is arranged in the hollow cylinder 14 of valve casing 12, second fluting, 28 fluid passages of opening between second fluid input 22 and second fluid output 24.As shown in Figure 1, when fluid passage that second fluting 28 is opened between second fluid input 22 and second fluid output 24, first fluting 26 is covered (Fig. 1 and 3) fully by valve shaft 16.Therefore, the part at first fluting, 26 opposite sides seals the fluid passage between first fluid inlet 18 and the first fluid outlet 20 in the valve shaft 16.
Equally, when axle rotor 42 during with valve shaft 16 Rotate 180s °, first fluting 26 is opened the fluid passage between first fluid inlet 18 and the first fluid outlet 20, and the part at first fluting, 26 opposite sides seals the fluid passage between second fluid input 22 and second fluid output 24 in the valve shaft 16.In the preferred embodiment, fluting 26,28 and enter the mouth 18,22 and export 20,24 size and design like this, so that the fluid passage between first fluid inlet 18 and first fluid outlet 20 is open-minded, the fluid passage sealing between second fluid input 22 and second fluid output 24.Equally, when open the fluid passage between second fluid input 22 and second fluid output 24, the fluid passage sealing between first fluid inlet 18 and the first fluid outlet 20.
As shown in Figure 1, a drive shell 46 is fixed on the valve casing 12, and it forms one and drives cylinder body 48.In the preferred embodiment, drive shell 46 is made by stainless-steel seamless pipe.Preferably, this drive shell 46 is fixed on the transmission case 50, and this transmission case 50 is preferably made of aluminum.In driving cylinder body 48, be provided with a piston 52.This piston 52 preferably is made of an aluminium lid 54 and an aluminium seat 56.Because this piston 52 is (stroke is indefinite) oscillating-type, this piston 52 is provided with a plastic sealing ring 58, pivots 2 ° from the position vertical with the central axial line that drives cylinder body 48 to allow piston 52, keeps the sealing between seal ring 58 and the drive shell 46 simultaneously.
One piston rod of preferably being made by hardened steel 60 is fixed on (Fig. 1) on the piston 52 by a set screw 62.As shown in Figure 3, piston rod 60 is provided with eyelet 62, and it is assemblied in the yoke 64 of a swing arm 66.In this eyelet 62, be provided with a needle bearing 68 or similar bearing well known in the prior art, to reduce friction.Needle bearing 68 is positioned at eyelet 62, and this eyelet 62 is arranged in locating stud 70 that this yoke 64, one made by heat-treated steel and passes first eyelet 72, needle bearing 68 and one second eyelet 74 of this yoke 64 and arrange.This locating stud is preferably made by heat-treated steel, to bear the immense pressure that produces when piston rod 60 activates.This swing arm 66 is preferably made by hardened steel, and is provided with a big hole 76, to hold a pair of driving back-up ring 78.This drives back-up ring 78 and links to each other with a live axle 80 by this way, in driving stroke, the energy of rotation of swing arm 66 is passed to live axle 80, and in recovery stroke, allow live axle 80, thereby make live axle 80 not rotate in the opposite direction with respect to swing arm 66 " idle running ".As shown in Figure 2, live axle 80 extends through transmission case 50, but to drive a vehicle or other any driving arrangement.
One fluid pressure generator 82 operationally is communicated with (Fig. 2) with first fluid 18 fluids that enter the mouth.In the preferred embodiment, this fluid pressure generator 82 is a steam generator, but natural, this fluid pressure generator 82 also can be any other similar devices.This fluid pressure generator 82 links to each other (Fig. 2,3) with first fluid inlet 18 by a delivery pipe 84, and in the preferred embodiment, second fluid output 24 also links to each other with this fluid pressure generator 82 by an additional delivery pipe 86.
As shown in Figure 2, this variable stroke motor 10 also is provided with an additional valve and piston assembly 88.The structure of this additional valve and piston assembly 88 is substantially the same with aforementioned components.But, as shown in Figure 3, this valve shaft 16 with first fluting, 26 and second fluting, 28 opposite positions on be provided with one the 3rd fluting, 90 and 1 the 4th fluting 92.As mentioned above, this arrangement of fluting 26,28,90,92 causes piston 52 drivings when the piston 94 of additional valve and piston assembly 88 is replied, and piston 52 is replied when the piston 94 of additional valve and piston assembly 88 drives.The complementary drive of this piston 52,94 causes live axle 80 to be driven continuously basically by two pistons 52,94.
As shown in Figure 4, two returning springs 96,98 are set, so that the swing arm 100 of aforesaid swing arm 66 and additional valve and piston assembly 88 returns back to initial position.When each swing arm 66,100 alternately moved to initial position, this swing arm 66,100 also moved to its initial position with their pistons 52,94 separately.This returning spring 96,98 is fixed on the transmission case 50 round live axle 80.Each returning spring 96,98 is provided with one and replys an arm 102,104 and a fixed claw 106,108.In case this returning spring 96,98 is fixed on this transmission case 50, this fixed claw 106,108 just is arranged in the hole 110,112 that is arranged on the swing arm 66,100.As shown in Figure 4, live axle 80 was connected on the interior week of a pair of driving back-up ring 114, and this driving back-up ring 114 is connected on the periphery of swing arm 100 conversely.This drives back-up ring 114 and is orientated like this, so that when swing arm 100 was driven by piston 94, this driving back-up ring 114 passed to live axle 80 with rotatablely moving of swing arm 100.In recovery stroke, moving back-up ring 114 " idle running " returns back to its initial position to allow returning spring 96 with swing arm 100, and big energy of rotation is not passed to live axle 80.
One anti-backlash back-up ring 116 is fixed on the live axle 80 between the swing arm 66,100, with the energy of rotation transmission between further reduction swing arm 66,100 and the live axle 80.As shown in Figure 4, this anti-backlash back-up ring 116 is fixed on the transmission case 50 in a drive shaft openings 118, and this drive shaft openings 118 is arranged in the transmission case 50 and between swing arm 66,100.
This anti-backlash back-up ring 116 is fixed on the transmission case 50 by weldment or other similar device.This anti-backlash back-up ring 116 adopts and drives back-up ring 114 similar structures, but is connected on the live axle 80 with opposite direction with respect to driving back-up ring 114.Therefore, when swing arm 100 was in its driving stroke, driving back-up ring 114 passed to live axle 80 with the energy of rotation of swing arm 100, drives in stroke at this, and anti-backlash back-up ring 116 is in its " idle running " direction, rotates freely to allow live axle 80.Drive stroke in case swing arm 100 finishes it, returning spring 96 just returns back to its initial position with swing arm 100.When returning spring 96 pendulum rotating swing arms 100, drive back-up ring 114 and be in its " idle running " direction, its restriction passes to live axle 80 with the energy of rotation of swing arm 100, and is reduced in the resistance on the returning spring 96.
Anti-backlash back-up ring 116 is used to prevent that live axle 80 is along being further rotated on the answer direction of swing arm 100.If the frictional force that drives between back-up ring 114 and the live axle 80 is enough big, in the recovery stroke of swing arm 100 a part of energy of rotation is passed to live axle 80 from driving back-up ring 114, then anti-backlash back-up ring 116 can prevent the rotation of live axle 80.Because anti-backlash back-up ring 116 is welded on the transmission case 50, therefore this anti-backlash back-up ring 116 passes to transmission case 50 with any " backward " energy of rotation of live axle 80, to prevent the rotation of live axle 80 along the answer direction of swing arm 100.
Anti-backlash back-up ring 116 continues to stop the rotation backward of live axles 80, and in swing arm 66 or 100 one drives in stroke till the beginning rotating driveshaft 80 at it.In this way, this anti-backlash back-up ring 116 can guarantee that live axle 80 is only along a single direction rotation.
In order to operate variable stroke motor 10 of the present invention, axle rotor 42 is driven, and is positioned at the valve shaft 16 of hollow cylinder 14 with rotation.Fluid pressure generator 82 is activated, with to first fluid inlet 18 and additional valve and piston assembly 88 accommodating fluids, for example steam.Thereby valve shaft 16 is with constant speed rotation.When with lower pressure when first fluid enters the mouth 18 accommodating fluids because first fluting 26 is opened the fluid passages between first fluid inlet 18 and the first fluid outlet 20, thereby have only a spot of fluid to enter in the driving cylinder body 48.Entering the fluid that drives cylinder body 48 forces piston 52 away from valve casing 12.Because the rotation of swing arm 66, the eyelet 62 of piston rod 60 is along with the to-and-fro motion of swing arm 66 pivots slightly.The pivot of piston rod 60 causes whole piston 52 with respect to driving cylinder body 48 slight inclination.Be to reduce inclination, piston 52 arranges like this, so that when its initial position and end position, and piston 52 equal slight inclination.So just, reduced the inclination of piston 52 when piston is in whole midstroke.Swing arm 66 and piston rod 60 are preferably designed so that its length is enough to piston 52 is placed an initial position, tilt 2 ° from upright position with respect to the central axial line that drives cylinder body 48 at this initial position upper piston 52.
How to tilt for detecting piston 52, hope detects in the whole stroke of piston 52, promptly, when fluid is applied in the first fluid inlet 18 with whole pressure, begin to charge into fluid along with driving cylinder body 48, piston 52 moves towards swing arm 66, and causes piston 52 away from valve casing 12, begins rotation thereby promote swing arm 6.Along with the rotation of swing arm 66, piston rod 60 pivots in the yoke 64 of swing arm 66.Piston 52 continues rotation, and is vertical with the central axial line of driving cylinder body 48 up to piston 52, when this occurs in piston 52 and is in 1/4 place of its whole stroke.
Along with entering into, more fluid drives cylinder body 48, piston 52 continues to pivot away from live axle 80, up to as shown in Figure 1, piston 52 is in 1/2 place of its whole stroke, in this position, piston 52 tilts 2 ° with respect to the vertical line of the axis that drives cylinder body 48, but the true dip direction of this true dip direction during with the initial point place is opposite.Continue to charge into fluid along with driving in the cylinder body 48, swing arm 66 is further rotated, and is in 3/4 place of its whole stroke up to piston 52, and in the fully rotation of this position swing arm 66, thereby piston 52 is vertical with the central axial line that drives cylinder body 48 once more.Along with continue to charge into fluid in driving cylinder body 48, swing arm 66 continues rotation, and piston 52 towards is with respect to tilt 2 ° the position motion of the vertical line of the central axial line that drives cylinder body 48.True dip direction herein and piston 52 true dip direction when initial position is identical.Under perfect fluid pressure, when opened between first fluid inlet 18 and first fluid outlet 20 each fluid passage, this whole stroke just took place once.
Therefore, with make when the initial position piston 52 perpendicular to the central axial line that drives cylinder body 48 and in its periodic process along with will the pivot mode of a very big angle of the rotary-piston 52 of swing arm 66 is different, this piston 52 is being started working with the position of 2 ° of the perpendicular direction inclinations of the central axial line that drives cylinder body 48.In this way, piston 52 begins with tilt 2 ° position of Vertical direction with one, through a vertical position, in opposite direction with tilt position, another vertical position of 2 ° of Vertical direction, and identical and Vertical direction 2 ° the position that tilts when finally turning back to, thereby finish a cycle period with initial position.In whole stroke, remain in the very little value with respect to the side-play amount of vertical position.
Although this variable stroke motor 100 fully can be as previously mentioned in whole stroke cocycle, this whole stroke is to realize under the situation of complete (maximum) hydrodynamic pressure.When having only less pressure to be applied in the first fluid inlet 18, piston 52 will move in the cycle at short stroke.Along with the increase of the hydrodynamic pressure that provides by fluid pressure generator 82, in each rotation of valve shaft 16, will there be more fluid to enter and drive in the cylinder body 48 by first fluid inlet 18, first fluid outlet 20.These enter the fluid that drives the bigger quantity in the cylinder body 48 makes piston 52 move rapidlyer, thereby produces more and more longer stroke.Swing arm 66 stroke that this is longer changes into more rotations of live axle 80.Because axle rotor 42 rotates valve shaft 16 with constant speed, no matter the hydrodynamic pressure that applies how, each circulation will take the same time.Therefore, in the same time, more rotations of live axle 80 will convert the bigger speed of live axle 80 to.
For each rotation of valve shaft 16, be located at the fluting of second on the valve shaft 16 28 fluid passages (Fig. 1) of just opening between one time second fluid input 22 and second fluid output 24.During this period of time, the power of returning spring 96 causes swing arm 66 to push piston rod 60 to piston 52, and then by second fluid input 22 and second fluid output 24 fluid is discharged driving cylinder body 48.This fluid turns back in the fluid pressure generator 82 by additional delivery pipe 86 subsequently, thereby can be pressurized once more and by motor 10 circulate (Fig. 2).Along with piston 52 is driven, additional valve and piston assembly 88 are worked in complex way, to drive live axle 80 when piston 52 is in its recovery stroke.As mentioned above, in the time of in recovery stroke, anti-backlash back-up ring 116 can prevent that swing arm 66,98 from passing to live axle 80 with energy of rotation.
To cause piston 52 to have different strokes because valve shaft 16, therefore changes the hydrodynamic pressure that enters first fluid inlet 18 with the rotation of constant speed, thereby and in the same time lag with bigger speed driving live axle 80.Fluid pressure generator 82 can be provided with a heating and adjust controller 120, a propane valve for example passes to the heat of fluid pressure generator 82 with change, thereby and change hydrodynamic pressure, therefore, this variable stroke motor 10 can directly change into a bigger heat energy the faster rotation of live axle 80.
The present invention is described and explained to above accompanying drawing and explanation only in the mode that exemplifies.But obviously, except the situation that claims limited, the present invention is not limited thereto.For those of ordinary skill in the art, can also make various improvement and variation to the present invention, these do not depart from the scope of the present invention.For example, the additional valve and the piston assembly of any number can be connected on the live axle 80; The size of the fluting of the fluid input of valve casing and fluid output and valve shaft can change in very wide scope etc.
