1. A hose bend bleeder in combination with first and second hoses, comprising:
- the hose bend bleeder being located at the bottom of a bend in a flow path established by the hoses;
the hose bend bleeder including a main passageway to establish a flow path from ends of the hoses through the hose bend bleeder;
the hose bend bleeder including a bleed passageway communicating with the main passageway and extending to an exit passageway, the exit passageway extending to an opening located at a lower elevation than the main passageway; and
a bleed valve interposed between the bleed and exit passageways to selectively open and close communication between the bleed and exit passageways.

9. A hose bend bleeder in combination with first and second hoses, comprising:
-
a first hose with an end connected to a first hose fitting, the first hose fitting being at a vertical elevation lower than the first hose, and a second hose with an end connected to a second hose fitting, with the second hose fitting being at a vertical elevation lower than the second hose; a hose bend bleeder having first and second openings connected to the first and second hose fittings, respectively, such that the hose bend bleeder is located at the bottom of a bend in a flow path established by the hoses; the hose bend bleeder including a main passageway between the first and second openings, the main passageway being collinear with the first and second openings and first and second hose fittings to establish a linear flow path from the ends of the hoses through the hose bend bleeder; the main passageway, first and second openings and first and second hose fittings being substantially equal in cross-sectional area to minimize resistance to flow through the fittings and hose bend bleeder; the hose bend bleeder including a bleed block offset in a downwards direction from the main passageway, the bleed block including a radial bleed passageway communicating with the main passageway and extending radially from the main passageway in a downwards direction, the bleed block further including a horizontal bleed passageway communicating with the radial bleed passageway and extending horizontally from the radial bleed passageway, and the bleed block further including a vertical exit passageway in communication with the horizontal bleed passageway and having an exit opening at the bottom of the bleed block; and a bleed valve interposed at a connection between the horizontal and vertical exit passageways to selectively open and close communication between the horizontal and vertical exit passageways.

10. A hose bend bleeder, comprising:
-
a hose bend bleeder having first and second; the hose bend bleeder including a main passageway between the first and second openings, the main passageway being collinear with the first and second openings to establish a linear flow path through the hose bend bleeder; the main passageway, first and second openings being substantially equal in cross-sectional area to minimize resistance to flow through the hose bend bleeder; the hose bend bleeder including a bleed block offset radially from the main passageway, the bleed block including a radial bleed passageway communicating with the main passageway and extending radially from the main passageway, the bleed block further including a parallel bleed passageway communicating with the radial bleed passageway and extending parallel to the main passageway from the radial bleed passageway, and the bleed block further including a perpendicular exit passageway perpendicular to and in communication with the parallel bleed passageway and having an exit opening at a surface of the bleed block; and a bleed valve interposed at a connection between the parallel bleed passageway and perpendicular exit passageway to selectively open and close communication between the bleed and exit passageways.
