Problems solved by technology

[0002] In the traditional X-rotor engine, in order to prevent the gas from leaking out of the cylinder due to the high pressure in the cylinder, the end face sealing groove is installed on the cylinder block to install the sealing strip, while the end face seal of the traditional X-rotor engine only considers the leakage from the cylinder to the outside environment. Mutual blow-by caused by different pressures caused by different strokes in adjacent combustion chambers is ignored, so it is necessary to improve the structure of the end sealing strip

[0027] combined with figure 1 And attached figure 2 Explain the gas blow-by of the combustion chamber of the traditional X-rotor engine. The rotor 2 rotates counterclockwise in the direction of the arrow. At this time, the combustion chamber 4a is in the combustion stroke and the combustion chamber 4b is in the intake stroke. Figure II The direction of the arrow is leaking, and the traditional end face sealing strip and radial sealing sheet cannot prevent gas leakage.

[0028] combined with image 3 And attached Figure 4 It illustrates the blow-by of the combustion chamber of the improved X-rotor engine. The improved end face sealing strip and sealing plunger can effectively prevent the leakage of gas and greatly improve the blow-by of the engine.

[0029] combined with Figure 5 The schematic diagram illustrating the assembly of the sealing plunger and the roller, the sealing plunger 9b is installed in the semi-cylindrical groove reserved on the cylinder body, the roll...

Abstract

The invention relates to a sealing system for a rotor engine, and belongs to the field of engines. The sealing system comprises an end surface sealing strip, a sealing plunger piston and a pin roller. Compared with a traditional end surface sealing strip, the end surface sealing strip used by the sealing system has the advantages that with the sealing plunger piston is additionally arranged; and mutual blow-by of gas in a combustion chamber is effectively prevented, and the problem of mutual blow-by of gas of three combustion chambers is effectively solved. The pin roller is adopted to replace a traditional radial sealing piece and single spring structure, rolling friction between the pin roller and a rotor replaces traditional sliding friction, and abrasion of radial sealing is reduced. The sealing device can solve the abrasion problem of the engine, improve the efficiency of the engine and prolong the service life.

Description

technical field [0001] The invention designs a sealing system for a rotary engine and belongs to the technical field of the rotary engine. Background technique [0002] In the traditional X-rotor engine, in order to prevent the gas from leaking out of the cylinder due to the high pressure in the cylinder, the end face sealing groove is installed on the cylinder block to install the sealing strip, while the end face seal of the traditional X-rotor engine only considers the leakage from the cylinder to the outside environment. Mutual blow-by caused by different pressures caused by different strokes in adjacent combustion chambers is ignored, so the structure of the end sealing strip needs to be improved. [0003] In the traditional X-rotor engine, the radial sealing plate and the rotor are in sliding contact, and the frictional resistance coefficient is large and easy to wear. Changing the sliding friction with a large frictional resistance coefficient into rolling friction wi...
