Abstract

An air-admitting guide member comprises an inflow end; an outflow end disposed on an inlet of a mechanical device; an elongated straight flow hole defined between the inflow and outflow ends; a plurality of rotational flow holes spaced apart respectively and each being defined between the inflow end and the outflow end, a diameter of the rotational flow hole being more than that of the straight flow hole and a bottom end thereof flushing with an end surface of the outflow end, the outflow end including a plurality of annular bores arranged on the end surface thereof and formed in a swirl shape toward the inflow end, an inner wall of the inflow end being formed in a tilted arc shape and including a stream-line sector end portion, the rotational flow hole including two openings arranged on two ends thereof individually, and projected shadows of the openings overlapping each other.

Claims

1. An air-admitting guide member being formed in a post shape and comprising:

an inflow end;

an outflow end opposite to the inflow end disposed on an inlet of a mechanical device;

a straight flow hole formed in an elongated hole shape, defined between the inflow end and the outflow end and located at an axial center of the post;

a plurality of rotational flow holes spaced apart respectively and each being defined between the inflow end and the outflow end, and a diameter of each rotational flow hole being more than that of the straight flow hole, a bottom end of each rotational flow hole flushing with an end surface of the outflow end, and the outflow end including a plurality of annular bores arranged on the end surface thereof and formed in a swirl shape toward the inflow end, and an inner wall of the inflow end being formed in a tilted arc shape and including an end portion formed in a stream-line sector shape, each rotational flow hole including two openings arranged on two ends thereof individually.

2. The air-admitting guide member as claimed in claim 1, wherein the number of the plurality of rotational flow holes is four.

3. The air-admitting guide member as claimed in claim 1, wherein the diameters of the rotational flow holes are of different sizes.

4. The air-admitting guide member as claimed in claim 2, wherein the diameters of the four rotational flow holes are of different sizes.
