Abstract
A separator arrangement including a tubular member extending along a longitudinal axis and a toroidal blade arrangement disposed within the tubular member in a fixed position. The toroidal blade arrangement can include a plurality of blade members, each being looped from a first end to a second end with a radially distal portion located between the first and second ends to define a radially bounded passageway extending along a second axis disposed at an oblique angle to the longitudinal axis. In one aspect, each of the blade members is looped such that an inner side surface presents both a leading face and a trailing face.
Claims20
A separator arrangement comprising:
- a) a tubular member extending along a longitudinal axis between an inlet end and an outlet end;
- b) a separation tube extending at least partially into the outlet end of the tubular member such that an annulus is formed between the separation tube and the tubular member;
- and
- c) a toroidal blade arrangement disposed within the tubular member between the inlet end and the separation tube, the toroidal blade arrangement including a plurality of blade members defining an inlet side and an outlet side, each of the plurality of blade members:
- i) extending from a first end to a second end and between an inner side surface and an opposite outer side surface;
- and
- ii) being looped such that a first portion of the inner side surface defines a leading face that at least partially faces the inlet side, and such that a second portion of the inner side surface defines a trailing face that at least partially faces the outlet side.
A separator arrangement comprising:
- a) a tubular member extending along a longitudinal axis;
- and
- b) a toroidal blade arrangement disposed within the tubular member in a fixed position, the toroidal blade arrangement including a plurality of blade members, each of which extends from a first end to a second end with a radially distal portion located between the first and second ends to define a radially bounded passageway extending along a second axis disposed at an oblique angle to the longitudinal axis.
A pre-cleaner for an air cleaner assembly, the pre-cleaner comprising:
- a) a housing extending along a longitudinal axis and between an inlet end for receiving an unseparated airflow stream and an outlet end for delivering a separated airflow stream, the housing including an ejection port for discharging contaminants removed from the unseparated airflow stream;
- and
- b) a separator arrangement disposed within the housing and configured to separate the contaminants from the unseparated airflow stream, the separator arrangement including at least one toroidal blade arrangement mounted in a fixed, non-rotatable position.
