Abstract
Scroll devices with cooling fluid supplied through a crankshaft are provided. The device may comprise an orbiting scroll operably connected to a fixed scroll and a crankshaft operably connected to the orbiting scroll. A first seal may be positioned about an outer surface of the crankshaft to form a seal with the outer surface. A second seal may be positioned about an outer surface of the crankshaft to form a seal with the outer surface. A first channel and a second channel extend through the crankshaft and are in fluid communication with the orbiting scroll and a fluid source and a fluid reservoir.
