[0002] A supercharger is a device by which a low calorific value gas engine increases the intake air pressure of a cylinder. The air before entering the engine cylinder is first compressed by the supercharger to increase the density of the air, so that more air can be filled into the cylinder, thereby increasing the power of the engine.

[0003] At present, the supercharger announced in the Chinese patent with the publication number of CN105723069A includes: an impeller for pressurizing the intake air of the engine E; a supercharger rotating shaft on which the impeller is fixed; and a supercharger housing that rotatably supports the supercharger rotating shaft. Inside the supercharger housing, a supercharger lubricating fluid passage for guiding the lubricating fluid OL to the bearing housing is formed, and an oil filter for removing foreign matters in the lubricating fluid OL is provided in the supercharger lubricating fluid passage. The oil filter is detachably installed on the supercharger housing by an operation from outside the supercharger.

[0004] In actual use, it is found that the supercharger is fixedly installed on the low calorific value gas engine by bolts. However, when the low calorific value gas engine works, it is easy to generate vibration, resulting in the loosening of the bolts, which affects the stability of the supercharger. Therefore, we propose an installation structure of a supercharger for a low calorific value gas engine to solve the above problems. Summary of the Utility Model

The relaxation mechanism includes a rotating rod and a limiting pressing plate. The rotating rod is rotatably installed on the mounting seat, the limiting pressing plate is fixedly installed on the rotating rod, and the limiting pressing plate is in contact with the top of the fixing bolt.

[0008] Preferably, a rotating groove is opened on the mounting seat, and the rotating rod is rotatably connected with the corresponding rotating groove.
