Scroll machine with injection and refrigeration system

A scroll machine (2) with an injection for a medium, having a machine housing (10) with a longitudinal axis (X), wherein a first scroll unit (100) with scroll channel (120) formed by a scroll rib (110), a second scroll unit (200) with a first side (201) and a second side (202) opposite the first side (201), wherein a scroll channel (220) formed by a second scroll rib (210) is provided on the first side (201), and a high-pressure chamber (30) which is arranged on the second side (202) of the second scroll unit (200) and connected with the scroll channel (220) via a passage (260) in the second scroll unit (200), are arranged in the machine housing (10) along the longitudinal axis (X),

• wherein the first scroll unit (100) and the second scroll unit (200) engage with each other to form pressure chambers,
• wherein the first scroll unit (100) can be moved relative to the second scroll unit (200) along an orbital path,
• wherein an intermediate base (50) is provided along the longitudinal axis (X) between the second scroll unit (200) and the high-pressure chamber (30),
• wherein a line (70) is provided for injecting the medium, which line connects a housing port (13) with an injection port (270) in the scroll channel (220) of the second scroll unit (200), and
• wherein the line (70) is routed from the housing port (13) past the high-pressure chamber (30) through the intermediate base (50)
• characterized in that
• the high-pressure chamber (30) is connected to an outlet (12) via a pressure connection (40), the pressure connection (40) being arranged in a plane transverse to the longitudinal axis (X) offset from a passage (260) comprising an outlet port (262).
