1. 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), and an intermediate base (50) 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) so as to bypass the high-pressure chamber (30) through the intermediate base (50),
wherein the intermediate base (50) is held supported on the machine housing (10) on the side facing the second scroll unit (200) by means of an axial lock (58) or a shoulder of the machine housing (10),
and wherein the intermediate base (50) encloses the high-pressure chamber (30) together with the machine housing (10).
