Technical Field

[0001] The utility model relates to the technical field of engines, in particular to a respirator structure of an engine valve chamber cover. Background Art

[0002] The diversification of vehicle functions requires the engine breather structure to be more and more compact, but the requirements for breather oil-gas separation are getting higher and higher. In the engine manufacturing process, there are many problems that the breather volume needs to be increased, but there is no fixed space around the breather. Rearrangement of the breather and surrounding parts requires many changed parts, which requires increased mold and development costs. In addition, there are many changes in parts and the quality risk is greater. Therefore, how to minimize the development of parts, reduce development costs and reduce quality risks based on the small space for the existing breather layout is an urgent problem to be solved in the current engine technology field. Utility Model Content

[0003] The utility model aims to provide an engine valve chamber cover breather structure, which solves the problem that the existing breather is difficult to install when using additional installation space on the engine valve chamber cover due to the increase in volume.

[0006] A steel screw sleeve is embedded on the base of the respirator, and the steel screw sleeve is located between the glue sol groove and the air inlet of the respirator. This solves the problem of increased cost and increased quality risk due to the small space around the respirator of the valve chamber cover, which requires rearranging the respirator and surrounding parts. During installation, glue is applied to the glue groove of the respirator base, and then bolts are passed through the through holes of the valve chamber cover mounting surface from the inside of the valve chamber cover and tightened into the screw holes of the screw sleeve of the respirator base to complete the installation without occupying other space of the valve chamber cover.

[0007] As a further preferred embodiment of the present invention, a bolt through hole matching the steel screw sleeve is provided at a position on the top surface of the engine valve chamber cover corresponding to the steel screw sleeve, and the bolt through hole and the steel screw sleeve are connected by bolts.

[0008] As a further preferred embodiment of the present invention, there are more than two steel threaded sleeves.

[0009] Ensures the stability of the installation.

[0010] As a further preferred embodiment of the present invention, there are three steel screw sleeves, and the three steel screw sleeves are evenly distributed around the air inlet of the respirator.

[0011] The three steel screw bushings ensure stability while keeping the number as small as possible.

[0012] Compared with the prior art, the utility model can achieve at least one of the following beneficial effects:

[0013] 1. A steel screw sleeve is embedded on the base of the respirator, and the steel screw sleeve is located between the sol groove and the air inlet of the respirator. This solves the problem of increased cost and quality risk of rearranging the respirator and surrounding parts due to the small space around the valve cover respirator. During installation, glue is applied to the glue groove of the respirator base, and then bolts are passed through the through holes of the valve cover mounting surface from the inside of the valve cover and fastened to the screw holes of the screw sleeve of the respirator base to complete the installation without occupying other space of the valve cover.
