Abstract
An air compressor includes a valve plate with cooling fins and a piston also having cooling fins. The valve plate includes an integral and angled valve plate outlet. The angling of the valve plate outlet reduces turbulence and improves compressed air flow. The pump frame of the gas compressor includes a lipless bearing bore, decreasing the distance between the portion of the frame supporting the bearing and the piston. The pump frame is flat such that a portion of the cylinder is over a portion of the motor. The flatness of this arrangement increases the strength of the pump frame. The piston bearing bore includes two clamping structures having screw holes. Each screw hole is formed from a series half-cylinder or barrel portions, which individually do not form the complete circumference of a hole. Such a screw hole does not require a core pull on casting, lowering manufacturing costs. The piston includes a piston seal which is angled with respect to the piston. The piston head is machined at an angle to lower the amount of dead space near the top of the cylinder. The compressor includes a fan which operates efficiently at different speed settings. The fan is a radial fan including …
