The compressed gas discharge orifice of the first phase 12 in the chamber of the first impeller 15 is in communication with the injection port of the compressed gas of the second stage 21 in the chamber of the second impeller 25.

The diameter of the first impeller 20 of the compressed gas motor of the first stage 1 is smaller than that of the second impeller 26 of the compressed gas engine of the second stage 2, in order to increase the surface of the blade of the motor teeth of compressed gas from the second stage 2.

The compressed gas engine of the first stage 1 not only has functions of decompression and stabilization, but also allows full use of the energy generated in the process of release of the compressed gas, as well as provides part of the power to the Same time. The compressed gas engine of the second stage 2 provides main power.

Example 2: Another compressed gas motor is provided as shown in the figure. 4, comprising a two stage compressed gas engine on the left side and a two stage compressed gas engine on the right side. The two stage compressed gas engine on the left side is a compressed gas engine of the first stage 100, while the two stage compressed gas engine on the right side is a compressed gas engine of the second stage 200. The compressed gas engine of the first stage 100 and compressed gas engine of the second stage 200 have the same structure, and are placed symmetrically on the left and right. The compressed gas motor of the first stage 100 and the compressed gas motor of the second stage 200 are coaxially installed on an axis 1 18, and connected with a fluted sleeve 17 through a bearing 108. The power generated by the Two-stage compressed gas engines (100 and 200) on the left and right sides exit through the shaft 1 18 to drive the drive shaft of the motor vehicle.

By taking the compressed gas motor of the first stage 100 by way of example, the compressed gas motor of the first stage 100 includes an impeller chamber 103, as well as a first impeller 104 and a second impeller 102 installed in the impeller chamber. 103 through the shaft 118. The impeller chamber 103 has different internal diameters coinciding with the diameters of the first impeller 104 and the second impeller 102 installed therein., so that the inner surface of the impeller chamber 103 relatively compacts the compressed gas in the working chambers 109 of the first impeller 104 and the compressed gas in the working chambers 16 of the second impeller 102. The impeller chamber 103 is provided respectively with a compressed gas injection hole of the first stage 106 for the injection of compressed gas to the first impeller 104, a discharge hole of the compressed gas of the first stage 11 for the injection of compressed gas from the first stage. impeller 104, a compressed gas injection orifice of the second stage 1 14 for the injection of compressed gas to the second impeller 102, and a compressed gas discharge orifice of the second stage 101 for discharging the compressed gas from the second impeller 102 The discharge orifice of the compressed gas of the first stage 11 is in communication with the compressed gas injection orifice 114 of the second stage through s a pipe 112, to inject the compressed gas from the first impeller 104 in the second impeller 102 to continue performing the work.

The first impeller 104 is provided on its circumferential rotating surface with a plurality of uniformly distributed teeth 1 10 and side plates 107 located on the right side of the teeth 1 10; the second pusher 102 is provided on its circumferential surface with a plurality of teeth uniformly distributed 1 15 and the side plates 105 located on the left side of the teeth 1 15 as well as the side plates 113 located on the right side of the teeth 1 15. The gas circuit of the first impeller 104 is isolated from that of the second impeller 102 through the side plates 113. The structures of the teeth 1 10 of the first impeller 104 and the teeth 115 in the second impeller 102 are similar to those of Example 1. A plurality of working chambers 109 are formed by the teeth 110 on the circumferential surface of the first driver 104 and the side plates (107 and 113) on either side between the front and rear teeth 110, and a plurality of gas chambers that allow the relative sealing of the injected compressed gas are formed by the inner surface of the impeller chamber 103 where the p drive impeller 104 and each of the work chambers 109. A plurality of work chambers 116 are formed by the prongs 115 on the circumferential surface of the second pusher 102 and the side plates (105 and 113) on both sides between the teeth front and rear 1 15, and a plurality of gas chambers that allow the relative sealing of the gas injected from the injection port of the compressed gas of the second stage 1 14 is formed by the inner surface of the impeller chamber 103 where the second impeller 102 and each of the work chambers 116.

The first impeller 104 is smaller in diameter than the second impeller 102, in order to increase the tension area of the teeth in the second impeller 102. In order to make the flow of gas more fluid, the discharge orifice first stage compressed gas 119 has a diameter 2-10 times greater than that of the compressed gas injection orifice of the first stage 106, while the compressed gas discharge orifice of second stage 101 has a diameter of 2. -10 times greater than that of the compressed gas injection orifice of the second stage 121. The times can be configured flexibly.

In particular, due to the high rotational speed requirement of the compressed gas motor (from 3,000 to 15,000 rpm), if the first impeller 104 and the second driver 102 are processed separately, it is difficult to guarantee the concentricity of the two (coaxial performance) ) due to precision machining errors, as well as complex processing technique and high processing cost. In order to improve the concentricity of the impeller and simplify the processing technique, the first impeller 104 and second impeller 102 are designed to have an integral structure processed as a whole.

The compressed gas engine of the second stage 200 includes an impeller chamber 205, a third impeller 204 and a fourth impeller 202. Apart from the difference in the compressed gas engine marks of the first stage 100, the compressed gas engine of the second stage 200 has a structure similar to the structure of the compressed gas engine of the first stage 100 (which will not be repeated here).

During operation, the compressed gas is first injected into the compressed gas motor of the first stage 100, and then enters the compressed gas engine of the second stage 200 after being decompressed and stabilized by the compressed gas engine of the first stage 100. The compressed gas engine of the first stage 100 not only has decompression and stabilization functions, but also allows full utilization of the energy generated in the compressed gas release process, as well as provides part of the power at the same time. The compressed gas engine of the second stage 200 provides the main power. More particularly, the compressed gas injected from the compressed gas injection port of the first stage 106 to the teeth 110 of the impeller 104 pushes the first impeller 104, and simultaneously, it is temporarily stored in each of the work chambers 109; and when the working chamber 109 temporarily containing the compressed gas is rotated to a position where the discharge port of the compressed gas of the first stage 11, the compressed gas in the working chamber 109 is expelled to the outside to do the work through the compressed gas discharge orifice of the first stage 11 1, further pushing the first impeller 104 to rotate. Meanwhile, because the discharge port of the compressed gas of the first phase 11 1 in the impeller chamber 103 is in communication with the injection port of the compressed gas the second stage 1 14, the compressed gas discharged from the orifice Discharge of the compressed gas from the first stage 11 1 continues to push the teeth 115 of the second impeller 102 to rotate to do the work through the injection port of the compressed gas of the second stage 1 14. The injected compressed gas is temporarily stored simultaneously in each of the working chambers 116, and when the working chamber 1 16 which temporarily contains the compressed gas is rotated to a position where the discharge hole of the compressed gas of the second stage 101 is located, the compressed gas in the working chamber 116 is ejected outward to do the work through the discharge port of the compressed gas of the second stage 101, pushing n over the second impeller 102 to rotate to do the job.
