Abstract

A blade for a stator in a torque converter including: a first blade segment connected to first inner and outer circumferential sections; a second blade segment, separately formed from the first blade segment, connected to second inner and outer circumferential sections, and including first and second portions; and a channel disposed between the first and second blade segments. In a circumferential direction, the first and second portions are separated by the channel.

Claims (49)

1. A blade for a stator in a torque converter, comprising:

a first blade segment connected to first inner and outer circumferential sections;

a second blade segment, separately formed from the first blade segment, connected to second inner and outer circumferential sections, and including:

first and second radially disposed sides connected to the first inner and outer circumferential sections;

a first radially disposed end connecting the first and second radially disposed sides; and,

a second radially disposed end connecting the first and second radially disposed sides; and,

a channel, wherein:

a first line, oriented only in a circumferential direction:

passes through the first radially disposed end or is co-linear with the first radially disposed end;

passes through in sequence: the channel, the second radially disposed side, and the first radially disposed side; and,

a second line, oriented only in the circumferential direction, passes through in sequence: the first radially disposed side, the second radially disposed side, the channel, the second radially disposed side and the first radially disposed side.

2. The blade of claim 1 wherein for a speed ratio of 0.0 for the stator, the blade is for enabling a flow of fluid for the stator through the channel.

3. The blade of claim 1 wherein for a speed ratio of 0.9 for the stator, the blade is for disabling a flow of fluid for the stator through the channel.

4. The blade of claim 1 wherein when an angle between a flow of fluid in the stator and an axial direction is less than a flow angle, the blade is for blocking a flow of fluid for the stator through the channel.

5. The blade of claim 1 wherein when an angle between a flow of fluid in the stator and an axial direction is greater than a flow angle, the blade is for enabling a flow of fluid for the stator through the channel.

6. The blade of claim 1 wherein:

the first blade segment includes a third radially disposed end connecting third and fourth radially disposed sides; and

a third line, oriented only in the axial direction, passes through the second radially disposed end and is off-set from the third radially disposed end in the circumferential direction.

7. A blade for a stator in a torque converter, comprising:

a first blade segment connected to first inner and outer circumferential sections and including first and second radially disposed sides connected to the first inner and outer circumferential sections;

a second blade segment, separately formed from the first blade segment and connected to second inner and outer circumferential sections; and,

a channel disposed between the first and second blade segments, wherein a first line oriented only in a circumferential direction passes through in sequence: the first radially disposed side, the second radially disposed side, the channel, the second radially disposed side and the first radially disposed side.

8. The blade of claim 7 wherein:

the first blade segment includes first and second radially disposed ends connecting the first and second radially disposed sides;

the second blade segment includes a third radially disposed end connecting third and fourth radially disposed sides;

a second line, oriented only in an axial direction, passes through the first radially disposed end and is off-set from the third radially disposed end in a first circumferential direction;

a third line, oriented only in the axial direction, passes through the second radially disposed end and is off-set from the third radially disposed end in a second circumferential direction opposite the first circumferential direction; and,

an entirety of the third radially disposed end is circumferentially located between the second and third lines.

9. A blade for a stator in a torque converter, comprising:

a first blade segment connected to first inner and outer circumferential sections and including first and second radially disposed sides and a first radially disposed end connecting the first and second radially disposed sides;

a second blade segment:

separately formed from the first blade segment:

connected to second inner and outer circumferential sections by third and fourth radially disposed sides: and

including:

a second radially disposed end connecting the third and fourth radially disposed sides; and

a third radially disposed end including a surface:

connecting the third and fourth radially disposed sides;

facing the second radially disposed side in an axial direction;

axially aligned with the second radially disposed side; and,

forming a straight edge beginning at the third radially disposed side and extending in a straight line to the fourth radially disposed side;

a channel disposed between the first and second blade segments, wherein:

a first line, oriented only in an axial direction passes, through the second radially disposed end and the second radially disposed side;

a second line, oriented only in a circumferential direction, passes through the third radially disposed end and the first and second radially disposed sides;

the straight edge is co-linear with the second line; and,

a third line, oriented only in the circumferential direction, passes through in sequence: the third radially disposed side, the fourth radially disposed side, the channel, the fourth radially disposed side and the third radially disposed side.

10. The blade of claim 9 wherein:

a fourth line, oriented only in the axial direction passes, through the second radially disposed end and is off-set from the first radially disposed end in a first circumferential direction;

a fifth line, oriented only in the axial direction, passes through the third radially disposed end and is off-set from the first radially disposed end in a second circumferential direction opposite the first circumferential direction; and,

an entirety of the first radially disposed end is circumferentially located between the fourth and fifth lines oriented only in the axial direction.
