Abstract
A filter for an oil catch apparatus is provided. The oil catch apparatus is capable of efficiently extracting oil from air flowing through the oil catch apparatus while being of compact size. The filter includes a cylindrically wound main filter unit, a first keep member for keeping one end of the main filter unit, and a second keep member for keeping the other end of the main filter unit. Air flowing into the main filter unit from an opening formed in the first keep member is cleared of impurities upon passing through the main filter unit, and exits out of the main filter unit.
Claims6
A filter, comprising:
- a cylindrically formed main filter unit,
- a first keep member configured to keep one end of the main filter unit,
- a second keep member configured to keep the other end of the main filter unit;
- and
- a muffler,
- wherein
- the muffler is located in the main filter unit and includes a muffler member located on the first keep member side inside of the main filter unit,
- the muffler member includes a surface member and a back-surface member, each formed of a mesh sheet, and a coupler member configured to couple the surface member and the back-surface member,
- the surface member and the back-surface member are arranged apart from one another in the axial direction such that air entering from an opening formed in the first keep member passes in the axial direction through the surface member, the coupling member and the back-surface member into an inner region of the main filter unit prior to passing radially outward through a cylindrical side of the main filter unit, and
- the air entering from the opening formed in the first keep member is cleared of impurities upon passing through the main filter unit and exits from a peripheral surface of the main filter unit.
