Abstract
An apparatus includes a motor with an output shaft. A solitary air compressor is linked to the output shaft so as to be driven by the output shaft. The compressor contains a piston in a cylinder. A first fan is mounted on the output shaft to direct cooling air to the motor. A second fan is mounted on the output shaft to direct cooling air to the compressor.
Claims9
An apparatus comprising:
- an air compressor having a cylinder;
- a motor having an output shaft;
- a flywheel;
- a drive belt extending between said output shaft and said flywheel so as to rotate said flywheel upon rotation of said output shaft;
- and
- a piston structure connected to said flywheel, said piston structure having an end portion received in said cylinder so as to reciprocate in said cylinder upon rotation of said flywheel;
- wherein said output shaft extends through an opening in said piston structure and moves around an ovate path of movement relative to said piston structure upon rotation of said flywheel, and said opening in said piston structure has an ovate periphery surrounding an open space which, in turn, surrounds said ovate path of movement.
4 more elements
An apparatus for use with a compressor cylinder and a motor output shaft, said apparatus comprising:
- an elongated piston structure having an end portion with a circular periphery configured for reciprocation in the cylinder;
- said piston structure further having an opening configured to provide clearance for the output shaft to extend through said piston structure and to move relative to said piston structure along an ovate path of movement within said opening upon reciprocation of said end portion in the cylinder, with said ovate periphery of said opening surrounding an open space which, in turn, closely surrounds said ovate path of movement.
