TWIN OPPOSING ECCENTRIC MOUNT FOR A ROLLING PISTON COMPRESSOR

摘要

An eccentric mount apparatus for a rolling piston compressor (10) includes a casing (12) having an inner radius (25). A rotary shaft (14) is mounted within the casing. A first eccentric (16) has a first greatest eccentric distance (28) and is rotationally fixed relative to the rotary shaft (14). A second eccentric (18) has a second greatest eccentric distance (34). A rolling piston (22) has a bore (36) formed therein, the second eccentric (18) being rotationally encased within the bore. The second eccentric is formed with an inner radial aperture (30), the inner radial aperture (30) being mounted to concentrically rotate about the first eccentric (16). Any opposing angular rotation between the first eccentric and the second eccentric results in an outward radial displacement of the rolling piston (22) thereby initiating contact between the rolling piston and the casing (12). A plurality of rolling elements (40) are disposed between said bore (36) and the second eccentric (18).
