Liquid cooling of a scroll device with liquid supply through integrated rotary unions

A co-rotating scroll device, comprising:

• a housing extending a length from a first end of the co-rotating scroll device to a second end of the co-rotating scroll device;
• a first scroll comprising a first involute disposed in the housing;
• a first scroll shaft comprising a first shaft axis, wherein the first scroll shaft is rotationally fixed to the first scroll, wherein the first scroll is configured to rotate about the first shaft axis relative to the housing;
• a second scroll comprising a second involute disposed in the housing;
• a second scroll shaft comprising a second shaft axis, wherein the second scroll shaft is rotationally fixed to the second scroll, wherein the second scroll is configured to rotate about the second shaft axis relative to the housing, wherein the first involute and the second involute are enmeshed with one another, wherein the first shaft axis is parallel to and offset from the second shaft axis;
• a first integrated rotary union arranged between the housing and the first scroll shaft, wherein the first integrated rotary union is configured to transmit a first coolant through a first sealed fluid flow path running from an inflow channel of the housing to a shaft inflow channel of the first scroll shaft, through a scroll coolant channel of the first scroll, through a shaft outflow channel of the first scroll shaft, and to a first outflow channel of the housing;
• and
• a second integrated rotary union arranged between the housing and the second scroll shaft, wherein the second integrated rotary union is configured to transmit a second coolant through a second sealed fluid flow path running from a second inflow channel of the housing to a shaft inflow channel of the second scroll shaft, through a scroll coolant channel of the second scroll, through a shaft outflow channel of the second scroll shaft, and to a second outflow channel of the housing.

A co-rotating scroll device, comprising:

• a housing;
• a first scroll positioned in the housing and having a first involute;
• a second scroll positioned in the housing and having a second involute;
• and
• one or more integrated rotary unions configured to transmit coolant from the housing to the first scroll and/or the second scroll.
