The specific embodiment
Schematically describe the intraware 10 of peashooter in the accompanying drawings.
The sealing of storage 11 usefulness lids can supplementing water via said lid.Riser 18 extends upward to storage 11.Riser 18 almost extends to the top of storage 11, so that its outlet is above water level.Riser 18 is connected to joint 17.Filling conduit 16 extends to filler 13 from joint 17.Filler 13 comprises reciprocating type handle 14, and it is connected to the filling piston 15 that is combined with check valve 43.Check valve 43 at the charge pump place prevents that air from flowing backward to the pump from riser 16.
The fluid switch 20 that is triggered by trigger 19 also is attached to joint 17.
Twin-tub 12 is positioned the below of storage 11, and said twin-tub 12 comprises the hydraulic cylinder 25 and large diameter pneumatic linear actuator 23 of minor diameter.Hydraulic piston 24 slides in hydraulic cylinder 25, and seals near interior casing wall 25 through O type circle.Similarly, air rammer 22 slides in pneumatic linear actuator 23, and has O type circle with near the interior casing wall of pneumatic linear actuator 23 and seal.Piston 22 and 24 interfixes through rigid links 26.The surface area of hydraulic piston 24 is less than the surface area of air rammer 22.
In the place ahead of hydraulic cylinder 25 hydraulic pressure bay 30 is arranged.Nozzle 31 extends to open space from hydraulic pressure bay 30.
The pull bar 41 that has brake component (catch) 27 at its far-end is attached to trigger 19, and emission bar 28 runs through brake component 27.
Space between multichannel bar 34 and fluid switch (multichannel pipe) housing forms pneumatic outlet 36.
In the accompanying drawings, water or other hydraulic fluids represented in letter " W ", and the pneumatic gas of letter " A " representative such as air.For simplicity, use word " water " and " air ".
During use, water is injected storage 11 and lid sealing storage 11.The handle 14 of charge pump 13 is moved back and forth in the air with the side waterborne in filling conduit 16, joint 17, riser 18 and storage 11 set up air pressure.
Hydraulic pressure in the water of storage correspondingly rises.Because inlet valve 29 is check valves, so water flow in the hydraulic pressure bay 30 and in the hydraulic cylinder 25 in hydraulic piston 24 the place aheads from storage 11.The air that accumulates between piston 22 and the conduit 21 will drain in the atmosphere through outlet 36 via the gap between the annular recess 39 on O type circle 37 and the multichannel bar 34.Nozzle group valve 32 cuts out, and hydraulic pressure and air pressure are set up in the reciprocating motion that continues of handle 14 in system.
When triggering trigger 19, trigger 19 moves past position to the position shown in Figure 3 of Fig. 2.The brake component 27 of pull bar 28 is pulled to abuts stop 40.In view of the above, emission bar 28 is opened the nozzle group valve 32 near back-moving spring 33.Simultaneously, annular recess 39 is forming runner around the O type circle 38 so that the compressed air at joint 17 places gets in the pneumatic linear actuator 23 through launch tube 21 rapidly.
If the air pressure behind the piston 22 such as be 50psi, then piston 22 and 24 diameter proportion will produce the hydraulic pressure that correspondingly increases in the water of hydraulic cylinder 25.Such pressure maybe be for about 90psi.Connecting rod applies between piston and equates and opposite power.Because it is dynamic (dynamical) that said motion comes down to, so it is inefficacious when nozzle is opened, to certainly exist some that cause owing to slight frictional dissipation and leakage losses.Clean power on connecting rod 26 left.Therefore, piston 22 and 24 as one man moves to the left side and passes the quick injection of nozzle 31 to cause water.
When releasing trigger 19 as shown in Figure 5, piston 22 and 24 is stuck in the left side and nozzle group valve 32 seals once more.As shown in Figure 6, the air pressure in the storage 11 will be shifted water onto in the hydraulic pressure bay 30 via inlet valve 29 once more.Under this configuration, multichannel bar 34 has moved to left so that annular recess 39 forms runner around O type circle 37, thereby under atmospheric pressure, escapes in the atmosphere via outlet 36 basically at the air at air rammer 22 rears.
System returns back to the configuration that Fig. 7 describes subsequently, so the remaining water yield has reduced the amount of overflowing via nozzle 31 in the storage 11.When the entity part of multichannel bar 34 sealed near O type circle 38, system can continue filling.
Should be appreciated that for a person skilled in the art, conspicuous improvement and replacement are regarded as the scope that does not exceed the utility model.
