The shape of described working cylinder inner carrier upper-end surface can for being conducive to increasing and the arbitrary shape such as extraneous wedge shape, waveform or zigzag fashion of carrying out heat exchange.
The upper-end surface of described working cylinder inner carrier is zigzag fashion upper-end surface.
The described ecp motor through piston type air compressor transformation, is characterized in that: the described bent axle the other end is provided with flywheel, the foreign steamer limit of described flywheel and the meshed transmission gear of starter motor.
The top of described working cylinder piston will be no longer a plane, but be designed to zigzag upper surface, the i.e. piston of " zigzag fashion ", object is to allow high-pressure air can carry out heat exchange with the external world fully when expansion work in cylinder at different levels, make gas isothermal expansion as far as possible, contribute to the power that raising air motor externally exports like this.In described two-stage working cylinder, the cylinder bore of the second level is larger than the cylinder bore of the first order.Reason is that pressurized gas are after first order cylinder expansion work, pressure energy can reduce, the pressurized gas entering second level cylinder through heat exchanger will continue expansion work, the pressure energy of gas is discharged to greatest extent, just require that the volume of second level cylinder or cylinder diameter are all large than first order cylinder, only in this way guarantee waste gas pressure close to and atmospheric pressure, thus make pressurized gas expansion work among cylinder as much as possible, improve air pressure energy utilization ratio.
Advantage of the present invention is:
One, the thinking that breaks traditions of unique innovation, air compressor retrofit is become the air-powered motor compared with forward position, and simplify the distribution device of air motor, structure is more simple, light, and the tightness of air motor is improved, and indicated power improves.
Two, improve greatly owing to utilizing double expansion acting to make air pressure energy utilization ratio obtain, reduce the energy contained by weary gas, make air motor power character better.
Three, electronic control is carried out to air motor, make air motor Power output more steady, adapted to the performance requirement under different operating mode, ensure that the isothermal expansion characteristic of high-pressure air as much as possible.
