A scroll compressor, comprising: a housing defining an internal cavity; a separator within the internal cavity of the housing separating a high pressure chamber from a low pressure chamber, the separator including a port fluidly communicating with the high pressure chamber; a fixed scroll body positioned within the low pressure chamber including a base, a scroll rib axially extending from a first side of the base, and an axially extending circular hub axially on a second opposite side of the base, the circular hub (172 defining a compression outlet extending through the circular hub and fluidly communicating with the high pressure chamber through the port; a floating seal arrangement interposed between the fixed scroll body and the separator, the floating seal arrangement sealing the compression outlet to the port and being axially moveable relative to the circular hub, the floating seal arrangement including: a floating seal; a first seal interface between the separator and the floating seal; a second seal interface between the floating seal and the circular hub, the second seal interface including a first seal member interposed between the circular hub and the floating seal; characterized in that a seal retaining ring limiting axial movement of the first seal member relative to the circular hub in an axial direction extending away from the base of the fixed scroll body is provided and that the first seal member is a spring energized seal including a resilient seal jacket and a seal spring positioned within the resilient seal jacket, that the resilient seal jacket is generally U-shaped in cross-section defining opposed seal surfaces, the seal spring positioned between the opposed seal surfaces and wherein in particular the opposed seal surfaces are a radially outer leg portion and a radially inner leg portion facing generally radially away from one another, that the circular hub includes a stepped outer radial profile having a first outer surface portion with a first diameter, and having a second outer surface portion with a second diameter greater than the first diameter, the radially inner leg portion seals against first outer surface portion and the radially outer leg portion is positioned radially outward from the second outer surface portion. a housing defining an internal cavity; a separator within the internal cavity of the housing separating a high pressure chamber from a low pressure chamber, the separator including a port fluidly communicating with the high pressure chamber; a fixed scroll body positioned within the low pressure chamber including a base, a scroll rib axially extending from a first side of the base, and an axially extending circular hub axially on a second opposite side of the base, the circular hub (172 defining a compression outlet extending through the circular hub and fluidly communicating with the high pressure chamber through the port; a floating seal arrangement interposed between the fixed scroll body and the separator, the floating seal arrangement sealing the compression outlet to the port and being axially moveable relative to the circular hub, the floating seal arrangement including: a floating seal; a first seal interface between the separator and the floating seal; a second seal interface between the floating seal and the circular hub, the second seal interface including a first seal member interposed between the circular hub and the floating seal; characterized in that a floating seal; a first seal interface between the separator and the floating seal; a second seal interface between the floating seal and the circular hub, the second seal interface including a first seal member interposed between the circular hub and the floating seal; characterized in that a seal retaining ring limiting axial movement of the first seal member relative to the circular hub in an axial direction extending away from the base of the fixed scroll body is provided and that the first seal member is a spring energized seal including a resilient seal jacket and a seal spring positioned within the resilient seal jacket, that the resilient seal jacket is generally U-shaped in cross-section defining opposed seal surfaces, the seal spring positioned between the opposed seal surfaces and wherein in particular the opposed seal surfaces are a radially outer leg portion and a radially inner leg portion facing generally radially away from one another, that the circular hub includes a stepped outer radial profile having a first outer surface portion with a first diameter, and having a second outer surface portion with a second diameter greater than the first diameter, the radially inner leg portion seals against first outer surface portion and the radially outer leg portion is positioned radially outward from the second outer surface portion.
