CS245295B1 - Air cleaner for internal combustion engines - Google Patents

Abstract

The solution belongs to mechanical engineering. The aim is to increase the reliability of the air cleaner. The stated aim is achieved by providing an air cleaner for internal combustion engines, comprising a cylindrical housing and a noise-damping attachment, cantilevered relative to the cylindrical surface and bent in a plane perpendicular to the axis of the housing. The attachment consists of an engagement part, the geometric axis of which is on a circle with a radius of R-j = /1.2 - 2.5/ Rc, where Rc is the radius of the cylinder and the connected part, connected directly to the housing, the geometric axis of which is on a circle with a radius of Rn, the center of which is on the cylindrical surface of the housing and the size is equal to the shorter distance between the surface of the housing and the geometric axis of the engagement part.
