The circular spiral piston motor or the engine achieves the advantages of low energy consumption, high speed and big torque of a motor or an engine by adjusting the relationship values of the diameters of the circular spiral grooves, the pitches of the circular spiral grooves and the diameters of a piston, is bigger in torque in the same speed, is higher in speed in the same torque, and saves more energy in the same speed and the same torque.
Description
[technical field]
The utility model relates to a kind of energy saving device, is applicable to air pressure motor, oil hydraulic motor and fuel type piston engine, refers in particular to circulation helical groove and adds air pressure motor, oil hydraulic motor or the explosive motor that piston forms.
[background technique]
There is contradiction state in current common air pressure motor and oil hydraulic motor: fast torsion is little between speed and torsion, the speed that torsion is large is low, the internal volume of its basic reason and piston cylinder has direct relation, the few speed of infusion time of internal volume hour gas or liquid is just fast, but torsion is very little, reason is that volume is little, lifting surface area is little, so working pressure is little, torsion is just little; Otherwise internal volume is large, the infusion time of gas or liquid is long, and speed is just slow, but torsion can increase thereupon, and reason is that the diameter of piston increases lifting surface area and strengthens volume and thereupon increasing, increased pressure and internal volume.In sum, it is high-speed that current air pressure motor and oil hydraulic motor are wanted, and torsion just diminishes, and wants large torsion to underspeed.
There is equally contradiction in current crank-axle engine, the motor that speed is high, torsion is large is all to realize by high energy consumption between speed, torsion and energy consumption.Its speed of motor and torsion that energy consumption is little are little, and its basic reason is also to have direct relation with the internal volume of piston cylinder, and the running radius of internal volume and bent axle also has direct relation.Crank throw is larger, and internal volume is larger, and energy consumption is just larger, and speed will be higher, and torsion is larger.Otherwise crank throw is less, internal volume is less, and energy consumption is just less, and speed will be lower, and torsion is less.
In sum, current air pressure motor, oil hydraulic motor, the piston-engined shortcoming of bent axle all embody a concentrated reflection of in the contradiction between internal volume, speed, torsion three.
