| 12 | Air compressor | US3779672D | 1971-03-01 | US3779672A | 1973-12-18 | SCHROEDER W |
| A compressor which is adapted to operate in a dry condition without any lubricant. The compressor has a cylinder which defines a compression chamber in its interior and which is provided with a gas intake and a gas outlet. A piston which is made substantially entirely of plastic reciprocates in the cylinder and defines a gap with the inner surface thereof, the gas inlet being in the form of nozzle-shaped openings extending through the cylinder wall and inclined with respect to the cylinder axis. In addition to the latter openings there are balancing bores which extend through the cylinder wall to provide a stable reciprocation of the piston, and the axes of these bores not only are inclined with respect to the cylinder axis but they are also inclined with respect to the axes of the inlet openings in a manner according to which air entering through the latter will retard any tendency of air or other gas to leak out through the balancing bores. Preferably there are a pair of pistons which are directly opposed to each other so that one reciprocates along its suction stroke while the other reciprocates along its compression stroke. According to the method the pistons are reciprocated at a speed of at least 1500 strokes per minute, so that in this way compressed air or other gas can be supplied to chemical, food, or other industries in large quantities for such purposes as the pneumatic operation of bulk material conveyors and the like.
