Filter-and-throttle unit for a scroll compressor, and scroll compressor for a refrigerant circuit

A scroll compressor includes a compressor housing, a high-pressure chamber, a low-pressure chamber, an oil return channel having an oil return throttle arranged therein, a driven eccentric unit, a fixed scroll, an orbiting displacement scroll arranged on the driven eccentric unit which interacts with the fixed scroll, a sliding disk arranged between the orbiting displacement scroll and the compressor housing, a back-pressure chamber arranged adjacent to the orbiting displacement scroll, and a gas connecting channel having a gas connecting throttle arranged therein. The oil return channel fluidically connects the high-pressure chamber with the low-pressure chamber. The gas connecting channel fluidically connects the back-pressure chamber with the high-pressure chamber. The oil return channel and/or the gas connecting channel extends through the sliding disk. The sliding disk includes the oil return throttle and/or the gas connecting throttle.
