Abstract
An apparatus for providing bleed air to exit an air outlet fitting where an air hose is connected to a turbine housing to cool the turbine and outlet fitting. The bleed air is directed through longitudinal channels outside the air hose and to an air diffuser collar where it is deflected to exit the apparatus radially.
Claims12
An air bleed apparatus for cooling an air supply turbine and hose in portable spray painting equipment comprising:
- (a) a generally cylindrical air outlet fitting having:
- (i) a first end having a shallow conical tapered surface for providing a relatively air tight connection to a housing of the air turbine,
- (ii) a second end having a bore adapted to receive an air hose,
- (iii) an intermediate region between the first and second ends having fastening means exterior of the fitting for securing the fitting to the housing, and
- (iv) a plurality of air passageways interior of the fitting extending from the intermediate region to the second end of the fitting for allowing air to exit the fitting exteriorly of an air hose received in the fitting.

A method of cooling a portable paint sprayer air supply turbine hose fitting comprising:
- (a) passing pressurized air into an air outlet fitting having inlet and outlet ends and mounted on a turbine housing;
- (b) bleeding a portion of the pressurized air axially along an interior bore of the fitting and exteriorly of an air hose received in the fitting, the bleed air traveling in a plurality of longitudinal passageways between the hose and the fitting;
- and
- (c) directing the bleed air generally radially outwardly from the fitting by deflecting the bleed air outward along a radially extending wall axially spaced apart from the outlet end of the fitting.
