Compressors

Abstract

Compressors are provided which include a motor having a drive shaft; a compression chamber, having an inlet and an outlet; a diaphragm, disposed within the compression chamber such that when the diaphragm is deflected back and forth between a first position and a second position air is drawn in through the inlet and forced out through the outlet; a crankshaft, operatively connected to the drive shaft; a shuttle, configured to be displaced transversely by rotational movement of the crankshaft, and positioned to deflect the diaphragm by its transverse movement; and a guide configured to inhibit non-transverse motion of the shuttle. In some implementations, the compressor occupies a total volume of less than about 15 cubic inches.

1 . A compressor comprising:
 a motor having a drive shaft;   a compression chamber, having an inlet and an outlet;   a diaphragm, disposed within the compression chamber such that when the diaphragm is deflected back and forth between a first position and a second position air is drawn in through the inlet and forced out through the outlet;   a crankshaft, operatively connected to the drive shaft;   a shuttle, configured to be displaced transversely by rotational movement of the crankshaft, and positioned to deflect the diaphragm by its transverse movement; and   a guide configured to inhibit non-transverse motion of the shuttle;   the compressor occupying a total volume of less than about 15 cubic inches.   
   
   
       2 . The compressor of  claim 1  wherein the guide includes a guide pin. 
   
   
       3 . The compressor of  claim 2  wherein the guide pin extends from a guide disk positioned adjacent the diaphragm opposite the shuttle.
