Claims11
A combined motor and compressor device for use in a refrigerant recovery or recycling apparatus, said device comprising
- a housing, said housing having a motor section and a compressor section;
- an elongated shaft rotatably disposed in said housing and extending from said motor section to said compressor section and extending from said motor section in a direction opposite said compressor section;
- a motor disposed in said motor section, said motor having a disc armature disposed on said elongated shaft and rotatable therewith,
- a compressor cylinder disposed on the outside of said housing in said compressor section, said cylinder having an axis which is perpendicular to the axis of said elongated shaft,
- a piston disposed in said cylinder for axial movement therein,
- a crank arm, having means connecting one end of said crank arm to said piston and means connecting the other end of said crank arm to said elongated shaft;
- and
- fan means connected to said elongated shaft at an end of said shaft opposite said crank arm whereby rotation of said shaft by said disc armature reciprocates said piston in said cylinder and spins said fan means.
