The trunnion of the crankshaft is coaxially fixed by shaft coupling with the output shaft of motor or air motor.
The upper end sealing of the delay casing guarantees that driving slider can withstand delay casing and open valve.
Use process and principle of the invention:
Power is provided for crankshaft by motor or air motor, is conducted by shaft coupling, when air motor generates power, crankshaft
Start to rotate around trunnion, the connecting rod neck band piston rocker motion of crankshaft, piston rocker arm pulls piston to make it along cylinder barrel
Wall moves up and down, and crankshaft, piston rocker arm and piston just form a simplest slider-crank mechanism, the revolution of crankshaft at this time
Movement has ultimately become limit linear reciprocating motion of the piston in cylinder barrel, and does not have quickreturn characteristics.
Simultaneously, while crank up campaign, another section of connecting rod neck of crankshaft drives connecting rod rocker motion, and connecting rod shakes
Armband is moved driving slider and is up and down reciprocatingly slided in limit sleeve first along the generatrix direction of cylinder barrel, crankshaft, connecting rod rocker arm and drive at this time
Moving slide-bar also forms a simplest slider-crank mechanism, and the rotary motion of crankshaft becomes driving slider in limit sleeve first
On limit linear reciprocating motion, equally without quickreturn characteristics.
The hinged valve of delay casing is being delayed because the limitation of the limit plate on cylinder barrel can only carry out lateral linear movement
Under the power conduction of casing and the pulling force effect of tension spring, the up-and-down movement for the casing that is delayed becomes the transverse shifting of valve, real
It is an orthogonal dual link slide block structure in matter, the cross spacing that the rotary motion of final crankshaft is changed into valve is reciprocal
Linear motion.
The principle of valve delayed start-up,
The upper end of driving slider is always positioned at the inside of delay casing, without departing from, when the pressurization of piston upwards air-breathing, this
When driving slider upper end be in idle stroke state in delay casing, valve is in close state, and installs and resets on the valve of top
Tension spring, it is ensured that valve, which is in, when driving slider is detached from delay casing closes state；
Piston continues up pressurization, and when driving slider also continues up, driving slider is still in idle stroke state,
But the locking hook and press head in stopper have knocked strip bulge, so that locking hook is pressed into advance, prevent locking hook pair
It cannot be detached from time both when delay casing generation friction causes delay casing to rise and pull down in advance, driving slider continues up
The mobile upper end that delay casing is withstood up to the upper end, and locking hook is just corresponding with the card hole on delay casing at this time, simultaneously
The press head of stopper is not entered in delay casing and is still pressed by strip bulge, and driving slider is further continued for moving up and support
Delay casing moves upwardly together, and then gradually makes two pieces of split valves mobile to both sides, is gradually opened gas vent, and at this time
Pressurization is had been carried out in cylinder barrel, as driving slider continues to move up, the press head in stopper progressively disengages strip bulge,
Locking hook is ejected under the action of the spring and protrudes into card hole, and driving slider gradually moves to the upper limit, and valve also fully opens
Realize exhaust；
Then driving slider starts to move oppositely downward, while also movement carries out air-breathing to piston oppositely downward, engages hook card at this time
The firmly card hole of delay casing drives delay casing to move downwardly together, in the guiding force and tension spring that casing moves downward that be delayed
Pulling force gradually close valve, driving slider moves gradually downward and the press head of stopper is made to knock strip bulge, makes card
Only hook is pressed into and then progressively disengages card hole and exits delay casing, and valve is fully closed rear driving slider and is in idle stroke shape
State, subsequently into subsequent cycle.
