An air inlet is reserved on the upper lateral wall in the middle of the cylinder body, a radial inlet valve is installed on the air inlet, an inlet valve spring is matched with the inlet valve, a vertical inlet valve rocker arm is installed at the outer end of the inlet valve, and an inlet valve cam shaft is assembled at the other end of the inlet valve rocker arm. An air exhaust opening is reserved on the lower lateral wall in the middle of the cylinder body, a radial exhaust valve is installed on the air exhaust opening, an exhaust valve spring is installed on the exhaust valve opening, a vertical exhaust valve rocker arm is installed at the outer end of the exhaust valve, and an exhaust valve cam shaft is assembled at the other end of the exhaust valve rocker arm. The multi-crankshaft synchronous compression engine solves the problem of low utilization rate of output power of an internal combustion engine and is of an optimal structure of the internal combustion engines.

Description

Many bent axles are synchronously to hydraulic motor

Technical field

The utility model relates to the dynamic power machine field, specifically a kind of structure of explosive motor.

Background technique

Present single axle explosive motor through fuel acting outputting powers such as burning vapour, diesel oil, has also consumed a part of kinetic energy in running, make the power utilization rate of actual output on the low side.

Summary of the invention

The utility model is for solving explosive motor, and the power utilization rate problem of lower of actual output provides a kind of motor that two pistons are made move toward one another of in a cylinder, installing.

The technological scheme of the utility model is that a kind of many bent axles comprise cylinder block, piston, connecting rod, bent axle, flywheel, casing synchronously to hydraulic motor; Its special way is; In the cylinder block in casing two pistons in opposite directions are housed, leave the firing chamber between two pistons, external connecting rod is equipped with in the outside of piston; Bent axle is equipped with in the outer end of connecting rod, and synchronous flywheel is housed on the bent axle; Leave suction port on the upper side wall of cylinder block middle part, intake valve radially is housed on the suction port, be furnished with inlet-valve spring on the intake valve, vertical inlet valve rocker is equipped with in the outer end of intake valve, and the other end of inlet valve rocker is fitted with inlet camshaft; Leave relief opening on the lower wall of cylinder block middle part, exhaust valve radially is housed on the relief opening, the exhaust valve spring is housed on the exhaust valve, vertical exhaust valve rocker arm is equipped with in the outer end of exhaust valve, and the other end of exhaust valve rocker arm is fitted with exhaust camshaft.

During work; By synchronous flywheel two bent axles are rotated synchronously; Through connecting rod two pistons are pulled to outer dead point synchronously by inner dead point, bent axle drives inlet camshaft through transmission device simultaneously, and inlet camshaft is stirred inlet valve rocker compress inlet air door spring and opened intake valve; The firing chamber of air in the suction port inspiration cylinder block, simultaneously fuel oil be atomized or straight spirt firing chamber in.

IC Intake Valve Closes when the piston arrives outer dead point, bent axle continues rotation promotion piston to inner dead point motion compresses air and fuel oil synchronously.

Ignition mechanism begins igniting or HTHP is lighted atomized fuel after compression arrives inner dead point, and the gas of expansion is pushed piston to outer dead point.

When the piston arrives outer dead point, bent axle drives exhaust camshaft through transmission device synchronously, stirs exhaust valve rocker arm compression exhaust door spring and opens exhaust valve, and high-temp waste gas is got rid of through relief opening.

The utility model can design synchronous bent axle more than two as required; Under the drive of synchronous flywheel or alternate manner; Make the piston on two bent axles or a plurality of bent axle, do move toward one another work in same firing chamber through the single piston that connecting rod drives on per two bent axles.

The technique effect of the utility model is, adopts above-mentioned technological scheme, can realize that a kind of effective raising Engine torque power increases power output, reduces many crank-axle engines of wearing and tearing and oil consumption.

Description of drawings

Fig. 1 is the structural front view of the utility model, and the accompanying drawing that makes an abstract.

In the drawings, 1 casing, 2 connecting rods, 3 exhaust camshafts, 4 exhaust valve rocker arms, 5 exhaust valve springs, 6 exhaust valves, 7 relief openings, 8 synchronous flywheels, 9 firing chambers, 10 cylinder blocks, 11 suction ports, 12 intake valves, 13 inlet-valve springs, 14 inlet camshafts, 15 inlet valve rockers, 16 pistons, 17 bent axles.

Embodiment

Below in conjunction with accompanying drawing embodiment, the utility model is further specified.

As shown in the figure, the cylinder block in casing 1 is equipped with between 16, two pistons 16 of two relative pistons for 10 li and leaves firing chamber 9, and external connecting rod 2 is equipped with in the outside of piston 16, and bent axle 17 is equipped with in the outer end of connecting rod 2, and synchronous flywheel 8 is housed on the bent axle 17; Leave suction port 11 on the cylinder block 10 middle part upper side walls; Intake valve 12 radially is housed on the suction port 11; Be furnished with inlet-valve spring 13 on the intake valve 12, vertical inlet valve rocker 15 is equipped with in the outer end of intake valve 12, and the other end of inlet valve rocker 15 is fitted with inlet camshaft 14; Leave relief opening 7 on the cylinder block 10 middle part lower wall, exhaust valve 6 radially is housed on the relief opening 7, exhaust valve spring 5 is housed on the exhaust valve 6, vertical exhaust valve rocker arm 4 is equipped with in the outer end of exhaust valve 6, and the other end of exhaust valve rocker arm 4 is fitted with exhaust camshaft 3.

During work; By synchronous flywheel 8 two bent axles 17 are rotated synchronously; Through connecting rod 2 two pistons 16 are pulled to outer dead point synchronously by inner dead point, bent axle 17 drives inlet camshaft 14 through transmission device simultaneously, and inlet camshaft 14 is stirred inlet valve rocker 15 compress inlet air door springs 13 and opened intake valve 12; The firing chamber 9 of air in the suction port inspiration cylinder block 10, simultaneously fuel oil be atomized or straight spirt firing chamber 9 in.

Intake valve 12 is closed when piston 16 arrives outer dead point, and bent axle 17 continues rotation promotion piston 16 to inner dead point motion compresses air and fuel oil synchronously.

Ignition mechanism begins igniting or HTHP is lighted atomized fuel after piston 16 compression arrives inner dead points, and the gas of expansion is pushed piston 16 to outer dead point.

When piston 16 arrived outer dead point, bent axle 17 logical transmission devices drove exhaust camshaft 3 synchronously, stir exhaust valve rocker arm 4 compression exhaust door springs 5 and open exhaust valve 6, and high-temp waste gas is discharged to outside the casing 1 through relief opening 7.
