1. A scroll device comprising:
an orbiting scroll operably connected to a fixed scroll;
a crankshaft operably connected to the orbiting scroll, wherein the crankshaft extends a total length along a longitudinal axis from a first end of the crankshaft to a second end of the crankshaft, and wherein the first end is arranged opposite the second end;
a first seal positioned about a first circumferential portion of an outer surface of the crankshaft to form a seal with the first circumferential portion;
a second seal positioned about a second circumferential portion of the outer surface of the crankshaft to form a seal with the second circumferential portion, wherein a first volume is at least partially defined by the first seal, and wherein a second volume is defined between the first seal and the second seal;
a first channel extending along a first channel axis completely through the crankshaft from a first opening disposed in a first portion of the first end to a second opening disposed in a first portion of the second end, wherein the first opening and the second opening are arranged in a line coincident with the first channel axis, wherein the first channel axis is parallel to the longitudinal axis, and wherein the first opening is in fluid communication with the first volume; and
a second channel extending along a second channel axis completely through the crankshaft from a third opening disposed in a second portion of the first end to a fourth opening disposed in a second portion of the second end, wherein the third opening and the fourth opening are arranged in a line coincident with the second channel axis, wherein the third opening is disposed within a periphery of the first end, wherein an entirety of the second channel axis is parallel to an entirety of the first channel axis, and wherein the third opening is in fluid communication with the second volume.
