US 2014/0369873 A1 · Compressor for Pressurized Fluid Output

Abstract

A compressor moves a fluid from an inlet to an outlet and provides a pressure differential there between due to respective pistons moving in and out of a plurality of piston chambers via a piston rod. A rotating shaft extends through a grooved end plate, and the rotating shaft is connected to either the grooved end plate or the piston rod. The grooved end plate defines an off center or eccentric groove. A bearing extends from the piston rod and fits within the groove such that when the rotational motion of the shaft rotates either the piston rod or the grooved end plate, the piston rod slides back and forth relative to the rotating shaft. Each position of the bearing within the groove determines a corresponding position of the piston rod relative to the rotating shaft. Each pair of pistons may extend from a single, continuous piston rod.

A compressor for moving a gas from an inlet to an outlet and providing a pressure differential between the inlet and the outlet due to respective pistons moving in and out of a plurality of piston chambers, wherein a rotating shaft extends in a first direction through a grooved end plate extending across the compressor in a second direction substantially perpendicular to the rotating shaft, wherein the rotating shaft is connected to either the grooved end plate or the piston rod, wherein the grooved end plate defines a substantially circular groove positioned off center with respect to the shaft, and wherein a piston rod extends through the compressor substantially perpendicular to the rotating shaft, the piston rod sliding back and forth relative to the rotating shaft such that the respective pistons are alternately closer to and farther from the rotating shaft, the compressor comprising:

a bearing extending from the piston rod and fitting within the groove in the first end plate such that when the rotational motion of the shaft rotates either the piston rod or the first end plate, the bearing traverses the groove in the first end plate, wherein each position of the bearing within the groove determines a corresponding position of the piston rod relative to the rotating shaft.

A compressor for moving a gas from an inlet to an outlet and providing a pressure differential between the inlet and the outlet, the compressor comprising:

a rotating shaft extending in a first direction through the compressor;
a piston rod extending through the compressor in a second direction substantially perpendicular to the rotating shaft and connecting respective pistons at opposite ends of said piston rod, wherein said piston rod slides back and forth relative to said rotating shaft such that said respective pistons are alternately closer to and farther from said rotating shaft;
a bearing extending from said piston rod;
a grooved end plate extending substantially parallel to said piston rod and defining a groove that receives said bearing therein, wherein the groove within said grooved end plate is off-center with respect to said shaft;
wherein said bearing traverses the groove when the rotational motion of the shaft rotates either said piston rod or said grooved end plate;
and
wherein each position of the bearing within the groove determines a corresponding position of the piston rod relative to the rotating shaft.
